Video transcript

so excited to have drew house in here you know very well known figure amongst kind of our team out here and for those who are maybe watching this video later a founder of Dropbox how many how many billions of people do have news yeah no it's more like hundreds of millions only 309-347-1728 or becoming and how did you try to set that up so my path started I was really little so my parents had a PC Junior so very first computer and I was really little and my dad so first I would just play computer games on it but a couple years later by my dad got it showed me how there's this thing on the computer called basic and so I was lucky they showed me how to write so my first lines of code and I was like really really little like how little I was five that's good yeah yeah I think I saw those two get in line and so as you can imagine and it you know turns out when you're in your when you're little like that you have a lot of free time on your hands and so I was always like playing on the computer and I really loved playing games and so that was actually why I wanted to learn programming to learn how to make games how these things worked and and like I'm going to insert of my exploration about the computer work that would figure out like how there's like just you know there's like files and like okay then when I save a game like I can go into that file might give myself like 32,767 lives you know like it's so like it would be all these little things like that and if only I could access this file from home and kindergarten I'm moving this floppy drive around yeah so I thought I was going to computer games that was those what I that would does what I was interested in beginning I was then as far as a job I start out babysitting really so I was very good at like like watching I was like 12 may 11 and like how the parents would leave I put the kids to bed and I like I was very good at watching like HBO and like [ __ ] this is like a requirement I got only like babysit for like families that had like good TV and like Pringles and things like that and I'm gonna do that as a red flag you're know your focal point was her cable exactly yeah and then like trying to like and then sometimes I'd be like watching something probably like shouldn't be watching there'd be like you know shooting or like bad words and you know I was very good at like listening from when the lock went there the key when in the lot oh yes anyway this has nothing to do with starring company but sometimes but then I got a little bit of an upgrade on the job front I was beta testing a game and an online game was maybe 14 and they were taking forever to build the game and so I started getting restless and curious and started poking around under the hood of this game and and I found all these security holes mmm I found all these vulnerabilities anyway first you discover these things you're like oh my god oh my god you know you I started impersonating like the developers and things like that and sort of making a little like a little bit of trouble but then I'm like Gaea send them an email and my guys you really should fix this you should fix this and you should have done this this way you shoulda done this way and I'm like you know really getting into it and they're like well do you want to work here yeah and so I end up working remotely as an engineer or like they're like do you want to fix those bugs and I'm like okay and then you know is the first kind of startup adventure first experience of many where my stock options were worth nothing and this is 14 14 14 years and that so is part-time remote and but it was like a cool thing to talk about in like biology class and and you know like I had to get my dad to sign all the employment paperwork and things like that so but that was the path this is literally working on a game but then fortunately there you know as you learn there's a lot of other things in life beyond like Unreal Tournament which are really interesting beyond what Unreal Tournament or Starcraft tournament yes and so does a little later on like PC PC eras like more like this Sierra games like yes quest for something that you guys work for me it was for me it was pong okay yeah that was our timeline that work we're losing it a little bit we have a little overlap me and then and then and then you go to MIT we had you know I met many of us have been there as well and you know I watched your commencement speech I watched your commencement speech which was great you know it helped that the guy before you really set a new low in terms of commencement speech quality but your speech was really I thought a really powerful speech and I think it kind of hit this issue of like you know you didn't plan on being you know drew Houston Dropbox founder but you did think you were going to be an entrepreneur I mean it seems like while you were in college you were constantly thinking about starting a business of some kind yes and your speech was great - I mean you I was like going for the no know what it feels good though you know you're sort of like there's no instruction manual for these things I'm like what am i split you start like googling excessively for like every commencement speech ever given before anyway so but no I I did plan to be I always was excited about doing something that was my own thing whether I was making a computer game and eventually as I learned more about business and starting a company I was always I just turned out that I had joined startups as an engineer or like an intern when I was little and then just didn't never really laugh did you keep doing that while you were in college I mean you already had that kind of experience yeah starting stuff like even your freshman year sophomore year were you doing stuff so the the game company unfortunately folded pretty quickly but that that then gives me that experience and let me get a job at a local company there's another startup actually but it was kind of an MIT MIT founders so there's kind of relation there but yeah in the summers I take classes and then every summer I would go work at first couple years it was the company that I worked at in high school so they were like maybe you know half hour away half hour outside of Boston yeah and the one thing that I think is mysterious for everyone and even sometimes when people ask me I don't have a clear answer because it's it's still a little bit mysterious is you know how do you stumble on this thing that you know just kind of takes off like wildfire that just just and you have an interest or I mean you actually started kind of a little bit closer to kind of what we do here at KY your first startup which I think you started your junior year was was was was around SAT was called accolade right so my you never know where these things are going to go because I mean I think anybody who grows up programming or whether it's programming or something else like there's always tinkering with things there's always just one project after another and four and then the first time I want to start a company I took I had was I took my junior year off from MIT so I took it I took a year leave which end up being was a really great experience and I promised my parents I would come back and I did but but so the SAT at the time was changed there was like all this all this change happening right there merging in the writing section it's gone from 1600 points out of 24 to from from 1600 to 2400 now I know there's all kinds of other stuff happening but this was back in the day where you know to study for the SAT you'd have to show up at some like horrible classroom and like 8:00 in the morning on a Saturday to listen to some like seventeen-year-old who didn't want to be there either and all those just reading out of a book like this was the state of the art in like SAT prep and we're like guys like the Internet it's not the Internet's been here for like a little while it's like it's been here for a long time like why are we still was like how my parents study for the SAT and so and so I teamed up with actually one of my former teachers from my high school and we started building a new kind of course or an online course for that for the what was then the new SAT and what's your less I mean what caused you to I guess not do that at some point you worked out for some time you do it was interesting as a so I started working on cuz I'm like here's here's like an opportunity here's something that my co-founder and I knew really well I mean I just you know I did I don't know I've I treated the SAT like one of things I really like to do is like reverse engineer like how things work take things apart so whether that's you know more typical stuff like the kind of tinkering that kids do or like you know one of my so I like or the finding all the security problems in that in that in that game I when I start working on the SAT II like I also had to study for it I was I was like how does this thing work and so you can as you know they're always like little tricks and little patterns you can take advantage of and I I'm like okay the only really hard thing about the verbal section is is the vocab because like you can in general you can teach someone how to do a sentence completion without even really teaching him it's taught words that are that are hard so I when I was 16 I wrote all this software to do kind of flashcards and adapt and remember which ones I was getting right and which ones I was getting wrong and things like that because I didn't why it was too lazy to like cut out all the paper flashcards and like this is so stupid and so I'd done that and that code actually was kind of on the shelf for five years and then and then I when the SAT changed and I had a friend of mine who was a teacher who had his own SAT course and then we had this whole shtick going I was at MIT he had graduated from Harvard like you know through as a result of all this like reverse engineering the SAT and studying a lot for I got a 1600 so I was like we had all like that boxes checked for the parents and we're like we know how this works so that it was really just seeing an opportunity and being like you know you don't attach too much of an outcome around it like I didn't have a goal like I need to make this much money or whatever sort of like another interesting project and probably the best party that was really just having an excuse to learn about business in like a rigorous way so and what I mean a rigorous way I mean like like I didn't know anything about sales or marketing or finance or like any of these subjects and they all seem very like remote and mysterious and so to combat this I would just go on Amazon and type in like sales and then like find like the top three rated or most popular sales books and just like read them and repeat that if you found that valuable and its really pursue release 'fl like the reading is like one of probably the most important reading about business is probably most important thing that's prepared me for running for running Dropbox and then what what was and you talk a little bit about it in the commencement speech but I find this transition is kind of the most interesting one is you know what you were working on this for two years I think in through your graduation what kind of you know it's hard is that you know you're told to persevere and keep working on something don't give up but at some point maybe you are kind of put a good time after but yeah so I it was super interesting the beginning because like you know and when you first get to work you you you you know you get down to such important orders of business of like all right you know I got a Photoshop a logo and print out business cards as a founder on them another very important thing and then hand them out to people so that so they so that they know that I'm a founder now you know it's like this is like the stuff you know I still do that yes but then you know what you realize is after that kind of you know after you're like incorporated and you get your like fax back from the Delaware Secretary of State and these things all seem very official and important you're like after your like day number 74 of like I got to take out the trash like you know we got to erase the whiteboard and like all is a it's like you're like actually this is a lot of work and which was it was good but so I think with my first company the I didn't none of neither of us knew what we were doing at all and so we're bootstrapping it there's just a lot of kind of manual labor around like I was you know we were too cheap to get like employees so have any any money so you know who's going to write the math questions is like me and that I just still remember having to like force myself to like write these math questions and draw these diagrams and be like alright so where did the train leave from last time okay so the train this train leaves you know Sacramento at data and like and so I'm like God at some point I'm just like I can't yes we have people who do that so it's actually quite fun yeah I seriously I find that I didn't and so but but to you know super feel your pain no is it no in but but the problem wasn't really the work it was just more like we were putting a lot of effort into it and not seeing a lot of return so it was for me it was it wasn't you know I it's kind of lost some of the variety of the work and and so I just got kind of it just became harder and harder I felt like I had to push myself like so much like it and you know I'm like this is it just became something I dreaded it became something right up like tricked myself into like making progress and I'm like and then I'd start like it's just like negative spiral right because you're like you start resenting the work you start getting mad at yourself cuz you're like why am I not more disciplined likewise like why and it's just like then which makes you resent it even more and thinks there's something wrong with your site it's like all stuff all this like stuff in your head and and then what happened was I had a friend of mine who started a company and did things a little bit more properly like he had a co-founder who was like really good friends with they raised money you know they could just set up the company like a good normal company and then they were just having a blast they were working would just every waking hour but like they was having fun like every minute is what it looked like and felt like and so I was like at first I'm like oh man maybe I'm really defective like look these guys are having no problem with this but then what happened was I actually started I would find these little side projects and I start working on a pokerbot again reverse engineering like three people said this is impossible alumni get as possible and so I was really good at the security encounter reverse engineering part of it and could do enough of the AI but you know and there's like this I was just possessed like I would be like dragging my computer's around everywhere like my parents would ask like what had me come up to New Hampshire because we like a little place like this place on a lake where you're like supposed to get away from technology you next thing I'm like putting like three monitors on like the kitchen stove because there's not enough room and like working on this thing and so it but it turned out I mean you never know how these things are gonna sort of all line up but then when I was working on I was still working on the SAT prep company and my friend Adam who I mentioned moved out to San Francisco next thing I know he's he's two years younger than me but the next phone call I get from he's like hey I've raised five million dollars and like I I was like that's a lot of money like that number has like two commas in it like what the hell and this is like my you know my little brother in our fraternity I'm like oh my god and so but it just turned out that you know in part it was sort of the setup was there like I really loved algorithms and distributed systems and I studied computer science and like these are my favorite things and so was sort of sort of fertile ground and then you know one time I lost I left my thumb drive at home and so I couldn't get any work done for my company and the sort of non PR like the Director's Cut version of sort of the Dropbox origin story you know so I was riding taking a ride on the Chinatown bus the Fung Wah from from Boston to New York and I left my thumb drive vine and I'm just like I hate I'm like you know what are you doing these situations you're like you know like oh I hate my thumb drive I'm like I hate myself so like stupid I'm sorry I'm so disorganized I keep doing this why can't I be better and you know just the self flagellation and that's like there's nothing else to do for like four and a half hours but but I had this three gigabyte Linux virtual machine image that I need to keep in sync across all these computers because I worked on with laptop sometimes sometimes a desktop sometimes another computer and like nothing there are a million things that claim to solve this problem and none of them actually did and so it was really personal frustration that led me to open up the editor and start right some code that eventually turned into a Dropbox although I had no idea that would be the case at the time you know I mean I think this is an important moment because you know a lot of times when you read about Dropbox you said oh yeah he had the idea of having you know sharing files across multiple devices and all that but you know whenever I realize like no that did what what's amazing isn't the idea is actually very old idea in fact you know almost anyone who's worked on data storage or anything has for the last 40 years has been trying to do this and so to me the power of almost the audacity of what is like this was like a big problem that a lot of really smart people had kind of tried to do as you mentioned maybe even launch companies on it didn't have really complete solutions what what was kind of going on in your head that convinced you that not like I think the past that I'm about to take on this problem is going to be the one that works well it was just so clear from trying all the other things that like all they're like a hundred things that claim to solve this on paper but in like in practice they never really worked and they're you know at school at MIT they have that you sometimes you like a campus network or a sort of hard core UNIX II kind of way of solving this problem but like for a Windows computer or like a Mac Book like there's you you know you're stuck carrying around a thumb drive and emailing yourself stuff and and that was your point I was more just amplify the frustration I'm like guys this is not a new idea we've thought about this is like the 60s all right like why the hell am i forced to do it like really made me upset and then I you know there's some conviction I would like a look you know that the problem with like the all the on line drives is like these very specific technical things where it's like you know it's all a big hack where the way the on line drive the eye drives and X drives and for every letter there's men a drive for all of them they all worked on the same basic principle which is like okay we're going to make we're going to trick your applications and operating system into thinking that instead of like when you're when a program write something to the disk instead of writing it to the disk on that inside the laptop it actually intercepts it sends it over to the Internet to server somewhere and gets it back so at first glance like this is a great idea we'll work with everything it's you know it's not that hard but the problem is you're set like if the server is 100 milliseconds away instead of five milliseconds away like your hard drive or less then you get all these inexplicable problems because like all ever like millions millions millions lines of code we're all written with assumption that this thing is like five ten milliseconds away and I'm going I'm going into detail on this example it's like this there's like no way you can ever make that work like you know it's just like laws of physics and so you need a completely different approach and sort of a hybrid we're like okay what you know you have big and cheap and fast storage locally and on a server that's but it's like two swimming pools connected by a straw right and so use the straw first use the straw well and to like make it so that you know you're not waiting for the swimming pool to make it back and forth like use it efficiently do that in the background sinking right so and then it it just turned out no one had gotten the technical part right but then there's also like a user there's like a design piece of like you know how do you design the interface how do you make this what's a metaphor that people can understand and then there's kind of it there's like an academic piece of which like the algorithms and you know how do you move the files around and things like that and store them but then there's like a lot of grungy kind of operating systems work where you know how do you make it so that you work in the oh the fat32 file system every other file system one it stores you know next to the name of the file it stores like when the file was modified and it's a timestamp and it's a resolution of one second it's actually more detailed map alyssum and then any bikes just randomly on some random operating sub sum random hard drive you can have a fat32 file system that stores that modification time with a resolution to two seconds and it's like none of the other ones do that but that one does and so there's all this weird complexity to the code or like you know windows xp service pack 3 there be bugs where like the swedish version of that not the norwegian version the swedish version of this light and would just like cause dropbox to crash and so you know part is those two things like one is you know a fundamentally different approach from what some of the other guys are doing and then two is the lot of just like that kind of obsession like the same thing the same way I was like obsessed with like making a very well-crafted like you know SAT question about quadrilaterals and making the diagram look like the actual list it was like then obsessing over making it really fast reliable and fixing that obscure bug with Swedish windows and and what did you realize you start on this you see a problem you start tackling it and it is an audacious problem to tackle when did you say this is real this is like I have a solution here like this is already better than what's out there in industry so first was when I just made something that worked for myself and I'm like I could actually I could actually use it like I would put save something and it would like show up on my other computer and I'd be like finally and then but but it really started to take shape once I made a video a demo video of Dropbox like three minute little it's it's still online somewhere or you can find it and and I put it on Hacker News there's this new site for startups and it just got a ton of it was like top a hacker news for like two days like if these were the old days so it was easier to do that but but that gave me like a ton of I mean I already decided to quit my job because I was is complicated so I just graduated I was working as an engineer at a start-up and I was moonlighting on my SAT brother thing that was the other thing so I you're asking why like why did I kind of get frustrated it's like we my co-founder wasn't going to quit his job I wasn't really either this thing was never really going to succeed but it wasn't it also wasn't going to die so like it just got kind of frustrating but anyway so Dropbox really the first real turning point was when I put the video up and then Arash my co-founder saw it on accra news like we got that later like a week later we got introduced through mutual friend I'm sorry from it Paul Graham I was over rosh my co-founder and then our first investor paul graham saw the video and emailed me saying because we just i just applied solo to Y Combinator with the idea and so so that's one is your second interaction with Paul Graham I had a complicated series of interactions before so Paul so Y Combinator is kind of like a plan College right lots of people want to get in not enough spots you have this very competitive dynamic and so actually the sort of admission system was how I thought about getting to Y Combinator and so I had actually been flown out to California to hang out with some other Y Combinator founders I also wanted to pitch Paul on Dropbox and so I showed up at Y Combinator a little early before one of the dinners and walked into in his office and asked if if I could show him Dropbox and he was very angry about that he did not visitors were not welcome so II but the problem with that it's like imagine you know we all remember applying to school imagine having like five minutes with like the Dean of Admissions and the one thing that they learn is that like you're an [ __ ] hey um know if I'm supposed to pay let's just keep it real sorry it's all the 12 year olds watching that's don't say that yes but um but but that first video was like huge in terms of getting started yeah and then you get started and I mean and I mean and this what year was this was 2007 2007 2007 and then it's just been kind of oh I mean I actually I don't think I've ever seen it you guys have got to be one of the fastest growing organizations maybe in the history of the valley oh so it's been growing quickly yeah they're all like people are sending all kinds of records these days but but the company in terms of headcount has grown really fast and then the user base has grown from a 2009 we're like a million users an hour over 300 and and we give into it you know we're like what are your you know kind of in hindsight or now that you can look over the last 7 years I mean what would have been and I almost view this if we were talking a little bit about this when before we did this is you know what's kind of your your your what would you've told yourself when you it was an 80 person organization or 90 percent organization that you know kind of like either ease your stress or let you know that something's coming or ways to manage it as you grow well I think there's a lot you know and it's hard to kind of boil it down to like pithy like phrases of like oh this is how you know you build a company it's like you know how do you play basketball like I want to take a while to explain right so but but I think the I don't really know how to play time not very good about that also I ok I'm not good horrible do we look like it alright so what I would say is some of the earliest most helpful advice that we got was really to focus on the people we brought into the company like make sure everybody's like really really talented like so that's probably the best like hack you can do to make everything else easier right because you know put a good person between you and all your problems right and and our angel investors and some of our early folks were like I'm just kept drilling that into our heads like make sure the talent bar is really high be very choosy and and I think just sort of an attitude of of really trying to systematically train to like understand like okay well you know here's what I'm dealing with today but I'm going to talk to people who are maybe 6 months ahead a year ahead five years ahead and like what are they doing well like what would they I asked as quite as I hope those talk another CEO could a thousand person company I'm like all right you know we're approaching a thousand people at Dropbox you know what what am I going to what am I going to see between a thousand two thousand what should i watch out for like what would you put in place now so that as you've done all these things and grown the company you know what do you wish you could do today so a lot of what I do is sort of think it is think about that and sort of all you have to be able to see around corners and one way to do that is reading one way to do that is having mentors and getting advice but and then the other thing that gives you some calm is that you know what you read on TechCrunch or in the press generally you know when someone tells a story of a company they're like oh yeah Dropbox it started out with not a lot of users then later they had a lot of users and they did great you know and they just have this sort of this like this narrative arc that they you just they're like you're like well the real truth is like is that this complicated stuff happened and this was actually really hard they're like yeah I know okay two kids two MIT kids in a dorm room have an idea they just you know and and so the truth is like it's actually very complicated and hard but that all kind of gets glossed over but when you read like profiles there's a lot of books that have been written about there lately that the everything store is a book about Amazon's great book Steve Jobs biography Google Apple Microsoft Facebook all these Intel like Oracle like I've read as much as many kind of profiles on tech companies and other companies as I could get my hands on over you know these companies over the last few decades and you know what you learn is that you know there's enough there's nothing once you sort of look behind the curtain there's nothing that's that magical and so and that's important for people to understand because you might think like oh I don't know anything about business so I should just go like no I'm never gonna be good at it because I've never been good at it and that's just something I should go get like a business guy or where a person like to to do that stuff because I'll never be good at it but it's actually something you can learn and so I think that mindset of like you know on a in a week you can probably limit it in terms of what you can do but like you know think about playing an instrument or becoming a doctor or like any things it's like all of us can realize like yeah it's a lot of work but I can sort of see a path from A to B turns out like most things you want to learn have that kind of potential like you can you whether it's public speaking or building a company or or any of those things like if you over if you have the attitude that like you know that and you give yourself time like you can actually pick these things up there's nothing that magical about them so and that's one thing from these profiles and then the other thing because you see in the early days they make all these like really crazy stupid mistakes and like do all these things they're like really really wrong and then that's also therapeutic is like you realize all these companies were like a total mess and actually I see Albert and the coroner Albert is an early drop boxer Albert can tell you how what a mess really Dropbox was and say so what you what you read about is actually not reflective of reality it's much Messier and kind of less current less glamorous process yeah and I'm about to open it go into some questions that from from the team but but just took my last question is you know where do you see a kind of Dropbox in 5 10 50 years you know at the end of your life what do you hope Dropbox has has done 50 years what were the I don't know if anybody's made it's like self-driving boats yet but that would be an innovation that's I mean but but in the in it you know you can't really look that far out but what we've realized and what we we talk a lot about is we have this opportunity where now we have a lot of resources a lot of really talented people we can solve these really big problems and then what we're really working on is building this home for everybody's most important stuff right because you think about your house 20 years ago like you'd walk into your house to be like you know mail on the table you'd go in your living room oh your photos are on your you know in your kitchen your photos are on your refrigerator right and you go down the hall and your briefcase has like your documents in like all that stuff is now on servers or in your Dropbox and so we need this like new kind of home so we we think all the time about like you know how can we save hundreds and millions of people from like these things are really painful and annoying about technology like all these little paper cuts like forgetting your thought like the equivalent of like these little thumb drive problems are like everywhere right and so how do we how do we find the biggest ones and solve them at massive scale and so and then specifically you know we started out with this app that you put on your computer or your phone that gives you just like Dropbox folder but really what you want is you know what you're using that folder for is often you're putting photos in there you know you're getting work done you're collaborating with other people and so we're starting to dig into some of those use cases a little more with things like we just launched a photo app called carousel which is like if the gallery on your phone had like every picture you've ever taken and if you could text like a hundred or a thousand photos and videos at a time that's what carousel lets you do yet for some reason that had not really existed or known like everybody has this problem just no one solved it yeah awesome so I'll go into some of these questions the first one this is this is from Marsha you can reach your hand wash if you where's Marsha I don't know where is Marsha well oh she's remotely so what's your typical workday like probably the biggest thing I spent time on is recruiting and so there's you know often there will be some kind of fire drill at night where it's like okay we're acquiring a company or there's some candidate and we're fighting with you know Google or some startup to try to get them you know there's a tug of war so it's like and like I'm often you know myself down here like going on going big-game hunting for people to join Dropbox you know so I'll be like in the Google campus or if you see me if you see me well these companies you know what I'm doing and so recruiting is the biggest thing and then a lot of that probably the next biggest thing is just meetings with small meetings and small numbers with people on my team around certain projects so every six months we pick like you know a dozen things that we really want to get that are really important that we want to get done and then I'll you know I'll be spending time with them be like okay here's this here's new stuff we're going to do in collaboration or here's you know what answering questions like that what is Dropbox like what should it be in five years what will it be in 50 years like how what kind of place do we want to create and so and so it kind of and then there's this very this is much longer tale of all kinds of other stuff with it's like partners or customers or you know just other things yeah it's a hard question to answer succinctly yeah that's pretty good this if I'm to show up at the cottage I had I made something that um downloads my Google Calendar and dude if I wrote Python script that down was my Google Calendar into an Excel spreadsheet and like triage is my time on websites it's you have to supervise you have to like you have to triage the stuff or you know have someone help you treat other stuff but but then I had these like rolling charts of like how I spent the last week or the last four weeks the last twelve weeks so that can cause a lot of people say like oh I'll use that all right that's interesting you know data analytics on your time it is that's it's it's super so I I did that more a like one of most important things you need to think of it like as your job gets more complicated there's just more stuff competing for your time it's really important to understand where it goes you know that's there's a book called the effective executive by Peter Drucker it's like that's like any book on management will like focus on that so you know but if there's nothing it's like no one's created a tool where you can see where your time goes and it's like everybody you know a lot of people have that problem so but anyway so yeah I have been at times very like about that very cool and so I have a question from Dylan dealership Dylan's right over there so where are some almost interested unexpected fun technical challenges that you and your team have faced in the process of scaling Dropbox to hundreds of millions of users so I think it's just fundamentally the challenge of Dropbox itself and we're building you know we're trying to build like the file system for the internet and so how do you connect you know a billion devices right and so that comes along with all kinds of technical challenges where you know people are saving a billion files every day on Dropbox and so you know that's more than there are tweets on Twitter and this is not like little 140 cases like your like wedding photos right yeah it Canet nothing you can't have a bad day alright so so so even just the core service but then you know as you branch out then there's all these interesting things with you know how do we make a there's more sort of far afield things like computer vision like how do we in for photos or something you might how do we organize your photos for you search you know pretty much every kind of like client software we have big data we have data science we have you know a bunch of infrastructure stuff every permutate every possible platform every if people are like really into like hard core algorithms we need like that if we hard people are like really deep into systems we like unlimited need for that bunch of storage stuff I mean it's just it's really all over the map like it feels like any permutation of technical challenge we have it at least in software yeah yeah absolutely and I think we have timing for one one one more so this from Joel virtual inertial right there so he'd like to hear about hack week and this is where we've had a little bit of we want to do more of this how did it get started and has has any what new stuff has come out of it has anything actually been productized and so hack week is basically something we do every year wherever you guys probably heard of a hackathon or like a one day hacking event but we're like alright let's take this to 11 we'll do a whole week because sometimes you know Dropbox it would've been hard to prove that in a day but actually the first prototype had something reasonably working in a week and and so it's something we do really to sort of get back to the spirit of like where we started where you know there are no constraints a lot of people were telling us that what we were doing was a lot of investors told me that Dropbox is it's a stupid thing to get into have a yet another storage company or all the other ones have failed but like it just doesn't mat like instead of like talking or debating like actually write code and just like and if you do it right like you can change how people think and so a ton of things have made it into the product from having to account having a personal and business account in Dropbox that was a huge project that started out as a hack week project one of my AK week projects was the new and the way you do notifications or like those sort of the menu bar and Dropbox is not like the native and like with you can see like what's changed and and have a different UI around that things like a bunch of security stuff so two-factor authentication was was something that that started there a lot of how you can like rewind your files or undo things that it was at a quick project and then a lot of other stuff which maybe didn't make it one-to-one like you're like make it pound for pound into the product but even just like the when we watch people build like all these apps on top of Dropbox like that informed like someone may like I'm you know a juke box kind of music player that's a separate app and it just sort of like plants a seed that may may manifest itself years later in something like oh well now instead of just having the Dropbox app you have all family of apps like carousel mailbox Dropbox so that it's it's really just a time for a just to work on anything except where you're supposed to be working on be like a Nunley unleash people and remember kind of like lift the constraints as day to day and three it's it's to change how people think about you know if you have an idea like prove it and begin you know you learn as people have like a lot of really this is a pretty amazing group of people we have in the company and then interns like take Dropbox and put put it in a weather balloon and put an Android phone into space where that this phone will be taking pictures of the ride up and down and so it's just crazy you just have this like pictures uploading the drop box of like space well I just want to thank you I think right you know I think I speak for everyone here that you know it's been a real treat to kind of get to know you just now so thank you very much thank you
