Dropbox Hits 25 Millions Users, 200 Million Files Per Day

Wow, the most impressive thing here is the exponential growth: 2 million users in late 2009, 4 million mid 2010, 25 million now.
- tzs 16y ago
  Looks like O(n^2) growth to me. If we take month 0 as being in late 2009, then it looks like at month n they have about 19x^2/162-5x/6+2 million subscribers.
  - anonymoushn 16y ago
    This is true of any function if you evaluate it at only 3 points.
    - tzs 16y ago
      That was the point.
  - tzs 16y ago
    Sigh My point was that calling their growth exponential based on three points is silly, because with only three points you can fit a wide variety of curves.

  I imagine word of mouth has been a big factor for Dropbox. Who here has not at some point sung the holy gospel of Dropbox to someone else? Especially study groups.

Very anecdotal..it would be interesting to note paying vs free users, which could be (very lightly) related to layman / techie usage (VERY lightly).

I know it will probably end up being the first $1 billion+ exit for YC but I'm really hoping it's the first IPO. It'd really put an end to the myth that YC startups are "dipshit companies" once and for all (not that Heroku didn't do a decent job of that).
- sahillavingia 16y ago
  Nobody says that.

    Yes, they do: http://www.avc.com/a_vc/2010/07/lead-investors-dipshit-companies-and-funding-every-entrepreneur.html http://www.avc.com/a_vc/2010/07/lead-investors-dipshit-compa... http://venturebeat.com/2010/07/29/angelconf-ron-conway-michael-arrington/ http://venturebeat.com/2010/07/29/angelconf-ron-conway-micha...

      1. No, he says other VCs think that the funding landscape in general creates dipshit companies. Not that YC companies are dipshit companies. 2. It's Arrington talking. ;)

  Your comment makes me wonder if Dropbox has an exit strategy. Or if they're going to do like Digg and sit there until the entire industry moves on. With anything cloud-related being big busines right now, Dropbox should quit winners and either sell-out or go public.
  - shadowsun7 16y ago
    I don't believe Dropbox has an exit strategy, at least not for the time being. From what Drew Houston has to say about the company[1], the big vision is to give everyone universal access to their files, regardless of where they are or what platform they're on [2]. That's something that they seem willing to commit to for the long haul. [1]http://youtu.be/eaJKPCdimLA http://youtu.be/eaJKPCdimLA - actual quote being (21:16 mins): 'I'm completely dedicated to Dropbox ... I mean we're starting with files but there's all kinds of other directions we can go ... we're a long long way away from you being able to sit down in front of any computer, device, and have access to all your stuff.' [2]The analogy that Drew used was Athena, which apparently is this infrastructure at MIT that gives you access to your stuff no matter which workstation you're on, on campus.

It'd be really interesting to see how many of their users are paying subscribers. Most of the heavy Dropbox users I know do have pro accounts, and for me, it's the best spent SaaS money I've every spent!
revorad 16y ago
A hockey stick made of money! Thanks Dropbox for setting such a kickass example of a great technology product and company.
citizenkeys 16y ago
Proving that dreams sometimes do come true, the Dropbox Y Combinator application from 2007: http://files.dropbox.com/u/2/app.html http://files.dropbox.com/u/2/app.html Google never got around to releasing the "G Drive". None of the other competitors for Dropbox ever caught on, either.
RK 16y ago
Maybe I should send an unsolicited job application to Dropbox for a (sexy) data scientist position. 25 million users is pretty crazy.
- jswanson 16y ago
  If you have the chops, you probably should. I'm pretty sure that until recently they had a position listed for a data analyst type.

    Do you even need UI designers especially that there is basically just no UI/Interaction?

      have you ever seen the web interface?
      - tuhin 16y ago
        Yes, but I honestly believe it suffers neglect and a lot can be done to improve it. I have never seen a posting for a UI Designer hence wondering. Also the major USP is that Dropbox behaves just like a folder on the OS and not a seperate entity.
        roc 16y ago
        I was just pointing out that there definitely is a UX piece and plenty of room for designer contributions. Not to mention the installers and the rarely-used menus and preference windows. Just because you don't see them very often doesn't mean they wouldn't benefit from thoughtful design.
edanm 16y ago
Dropbox is the best startup to rise in the last few years. In terms of startups I use that have actually changed the way I use computers in a huge way, it is right up there with Facebook. It is one of the services that I simply could not imagine living without, now that I know it exists. If you haven't used it, or are still on the free plan, you really should try it out and buy at least 50gb. Stick all your most important files in there, and forget about that annoying thing called "backups".
- kjbekkelund 16y ago
  That's what I've done. And it's amazing having access to all the files from my iPad, iPhone and generally, for those few times I need it, from everywhere through the website. It's made my life a little simpler, that's for sure.
- JonnieCache 16y ago
  >Stick all your most important files in there, and forget about that annoying thing called "backups". Good luck with that, when dropbox has its first inevitable data loss incident. If you don't have physical control over the hardware, it doesn't count as a proper backup.
  - ladon86 16y ago
    I care less about the backups because I have Backblaze covering my whole Dropbox folder anyway, but I can forget about that annoying thing called "USB sticks" - for me the real benefit is file transfer and access across devices, not backup.
  - TillE 16y ago
    The neat thing about Dropbox is that your files get automagically mirrored to all your computers with Dropbox installed. So unless the client blows up too, odds are good that a data loss incident on their servers wouldn't be catastrophic. This isn't an enterprisey backup solution by any means, as I don't believe previous versions are stored locally. But it's a whole lot of really convenient redundancy.
stef25 16y ago
Dropbox worked great for me for quite a while. Then my Keypass password.kdb file got corrupted. This file contained all the passwords to my personal / freelance and office projects. Impossible to retrieve the data. Major PITA. So now I just use it for funny pictures and music but I don't trust it with really important things anymore.
- ssebro 16y ago
  I'm pretty sure dropbox does file versioning, so you should be able to revert to an earlier (uncorrupted) version of your file. Tell me if that works for you, b/c I use dropbox+truecrypt for hosting my super important docs...
  - stef25 16y ago
    Can't seem to find a mention of file versioning anywhere. When I login into Dropbox I find the file via search, clicking on it just downloads it. When I try to open the file it says The following error occured while opening the database: Hash test failed. The key is wrong or the file is damaged.

      To get a previous version of a file, login to Dropbox.com, browse to the file you'd like to get a previous version of, then hover over the file and click the blue arrow on the far right that'll appear beside the file change date. This menu lets you, among other things, restore old versions of the file. Select the "Previous Versions" button to see all of the versions of the file from the past 30 days on any free or paid account, or if you have the packrat upgrade enabled, then you can see unlimited previous versions. Hope that helps!

Has dropbox taken money since the $6M in 2008? Their financials must be incredible. If it costs $2/yr to support a free customer, they must already have 500k paying customers to cover the cost. They could just as easily have 1M paying customers and be wildly profitable. My guess is they are keeping their financials a massive secret, because if they became public it would invite competition from copycats with a budget for TV ads.
- jackowayed 16y ago
  They do have something like 40 employees, so they're spending on the order of $10M/year on salaries + benefits + office + etc. That said, I get the impression (from how PG talks about them, the fact that they seem to have supported this massive growth in users & employees without more funding, etc) that they are doing very well, and improving quickly.
  - roel_v 16y ago
    I don't know - the Backblaze guys did several blog posts on the economics of online file hosting/backups and it came out very expensive in terms of hardware. Plus the custom software and management. Dropbox accounts are generally small, so maybe that's making it easier. I'm not saying they aren't doing fine, just that online backups are low margin (Dropbox is special, they aren't regular 'online backup' providers, I realize; and they operate at a premium price point; but still...

I am massive fan of Dropbox and like to see it doing well. I have talked about its virtues on many Quora posts. I have ussually recommended using a Truecrypt volume within the Dropbox folder to guarantee encryption. Now reading findings like this and the authentication issues exposed in the last few weeks I'm getting quite worried about the security of the whole solution. Going to have to change a lot of my posts to say do not store anything sensitive without Truecrypt: http://paranoia.dubfire.net/2011/04/how-dropbox-sacrifices-user-privacy-for.html http://paranoia.dubfire.net/2011/04/how-dropbox-sacrifices-u...

Thanks to Dropbox my photo sharing site has the world's best uploader. (1) Since it's an ordinary folder, all photo management software (iPhoto, Aperture, Lightroom, etc.) can export to it without installing a plugin. (2) People can queue up photos to upload while traveling even if they're currently without Internet access. (3) Mobile clients are already built, and people can use the same client either to upload to my site or to send to their desktop for post-processing. If you're running a site that people upload files to, I highly recommend integrating with Dropbox. They have an API, but I just did it by letting people share a new folder with box@ourdoings.com and pulling photos from that folder.
- joelhaasnoot 16y ago
  Sounds great for people that already have dropbox, for others that might not work so great. Most savvy computer users understand dropbox, but sometimes (less savvy users) just can't get it to work.
  - brlewis 16y ago
    I wouldn't make it the only upload method, but I highly recommend it at least as an option. And with 25 million users, there's a good chance a lot of your new users already have Dropbox, especially within the early adopter crowd.

Dropbox it's ok, but what I'd really love is a software which does something a bit different: to arrange all the unused space in the hard disks of a LAN as a big virtual folder, with redundancy and all. Every time I think of the Outlook-and-Word users I have at the office with 500Gb hard disks...

Dropbox had helped me accomplished the impossible. Convincing a girly teenage girl to have a habit in backing up her computer regularly. No other service could do that, not even Time Machine.
sdizdar 16y ago
Amazing... One thing I would like to point that even though people claim that systems such as Dropbox are "simple" it is really not so simple to implement. Just ensuring that Windows piece does not mess up your computer (eat all your CPU, bandwidth etc.) is really hard. There are a lot of not-so-sexy work behind the curtains. BTW, we just started private beta for cloudHQ for Dropbox (http://www.cloudHQ.net/dropbox http://www.cloudHQ.net/dropbox). Basically this service provides synchronization of Google Docs and Dropbox files and backup of Google Docs to Dropbox. And we have a cool thing that you can edit Dropbox files directly with Google docs (you need to install our Google Chrome extension). We need some beta testers ....

Just ensuring that Windows piece does not mess up your computer (eat all your CPU, bandwidth etc.) is really hard. There are a lot of not-so-sexy work behind the curtains. BTW, we just started private beta for cloudHQ for Dropbox (http://www.cloudHQ.net/dropbox http://www.cloudHQ.net/dropbox). Basically this service provides synchronization of Google Docs and Dropbox files and backup of Google Docs to Dropbox. And we have a cool thing that you can edit Dropbox files directly with Google docs (you need to install our Google Chrome extension). We need some beta testers ....
