Dropbox is hands down the best piece of software I've installed in the past few years. It's the first product I've ever been able to recommend to both friends (geeks) and family (categorically not geeks whatsoever) without having to change my explanation of why it's so awesome.

Congrats guys!


I agree and congratulations to the whole team. I have been a huge fan and loved their free service. However, as soon as I moved to the paid service and increased my backed up data to 10GB my computer became extremely slow. Dropbox is using 98% of CPU both on windows XP and Mac. It has been a week and not everything is backed up yet. Moreover, if I move a directory within my dropbox folder, it takes it as a new folder completely and tries to delete and back it up again which is completely opposite to their philosophy. Also, if you want to back up 2-3 computers at the same time everything screws up. So, a word of advice while using dropbox, be patient, dont get too excited after using their free service and jump the gun from 2GB to 20GB, do it slowly and carefully and hopefully things will work out great.


Me too, and I was only on the free version. After trying to copy a couple of thousand tiny text files, I had to force kill explorer repeatedly until I gave up and uninstalled Dropbox.

In the end I just signed up for a $9.99 a year hosting plan with 20 gig of storage and WebDAV. Cheaper, faster, and no funky software to crash my boxen.

Honestly I'm not even really sure how Dropbox ever became so popular.


- Over the summer Dropbox raised a $7.25 million Series A round from Accel, adding to $1.5 million in seed money it brought in from Sequoia Capital and Y Combinator in 2007

- San Francisco-based Dropbox has just 20 employees.

I wonder why they need so much money. If the Freemium model is working, shouldn't they at least be breaking even?


I wonder why they need so much money.

Pretend I have a machine where you insert a quarter and, a year later, a dollar pops out. Do you a) insert the quarter you have in your pocket, wait a year, and then put all four quarters back in or b) go to the bank, borrow as much money as they'll give you, get it changed into quarters, and start stuffing the machine?

A freemium startup which has a good idea of what customer lifetime value is and what customer acquisition costs are is, essentially, a quarter-into-dollar machine.

This factor becomes particularly acute when the ultimate goal of the startup is to sell their quarter-into-dollar machine for some multiple of the number of dollars it has produced in the most recent year.

I appreciate the tone.

That aside, you are assuming growth is constrained in some way that money relieves. IE they need money to promote or they need money to support their free users until they mature into premium users. Either one of those is a sufficient answer.


What he's saying is that perhaps Dropbox can buy a user for $1 (via adsense, whatever) and make $2 off them. In that case, it makes sense to take all the money you can and plow it into customer acquisition.

At some point the law of big numbers becomes a limiting factor, but probably not at any point that would make it unwise to take $7m.


Not to mention that there is a lot more that can be done in that space from an engineering perspective. Files syncing could be just the beginning. What about consumer MVC from files to web services? Edit a photo on iphoto and it automatically changes on every service that uses it.

The "data keeper" role is like an octopus, big in the middle, tentacles everywhere. I could imagine a world where that role becomes as important if not more than the OS / services.


I understand the principle of taking investment to enable growth. It is not just a principle. It has mechanics to it.

one option A common way this works is putting that money to work acquiring more customers. This can mean sales staff. It might mean advertising. It might mean outlets. etc. It works if you have some way of converting money in to customers in a reliable way. Since dropbox appears to be growing virally through referrals, I don't see how this can be the case here. You cannot easily turn cash in to referrals. If it is a case of putting money to work acquiring customers, there is something I don't understand going one.

The other option I can see is funding the free accounts while you wait for premium accounts to open. If you are in a fast growth period, you might have a higher ratio of free/paid customers then what you expect the long term average to be. If you are growing very fast or your profit margins are relatively narrow, you might need some funding. IE, you might dip under profitable temporarily while you wait for the many new customers to convert. This kind of a need is short term & marginal. $7.25m is not marginal.


I understand what you're saying and think it is plausible given your assumptions. For example, you think that Dropbox's primary acquisition engine is viral referrals, that the number of referrals it gets over a certain interval is the number of new users times some constant conversion rate, and that you can't just increase that number of referrals by dumping money at it like you could increase the number of new users by dumping money on an effective CPC campaign.

I think your assumptions are likely to be contrary to material fact. In particular, I think that the embedded assumption of "constant conversion rates" is false. For example, I think that inducing a customer to give a referral is a conversion like any other, and that one could spend a non-trivial amount of engineering resources to instrument one's site and then spend engineering/marketing resources to A/B test the "#$#$& out of it, and this process would predictably result in increased conversion rate. (Test the call to action. Test the design of the form. Test integration directly with Facebook. Test how much free space you offer for a signup.)

Do I have to mention that A/B testing in the context of a viral loop is hypereffective because of compounding? You get exponential returns to linear improvements. This is on top of A/B testing tending to give exponential improvements to linear work, because today's improvements compound on yesterday's.

The combination of these two factors means... wow. That's like a repeatable recipe to... wow. Crimety. I think I have to spend some more time thinking about this later, but my snap impression is that you could have Zynga-esque growth in an arbitrary niche (i.e. selling to people who pay money for things) without scamming anyone.


$7m to optimise for more referrals?

BTW, my original comment was not 'what idiots' it was, 'I wonder what they need all that money for?' If they are going to spend it all on split testing their 'refer a friend' system, well that is something of a wonder.


While I'm sure buying online ads will be a large part of their strategy, they may be using this money to start experimenting with other forms of advertising: magazine, radio, etc. I'd assume they are also ramping up to a more aggressive corporate sales strategy.


Let me see what we have on this post so far as ideas:

- adwords

- Advertising experiments

- a/b teting ($7m in split testing. Wow!)

- Engineering. Go past just file syncing (uuilly)

- corporate sales

Each one of these is interesting in a way. I honestly don't think that the first three are likely. The last 2 are a strategic change of direction.


Raising money isn't always a reaction to bleeding money. Maybe they've nailed down their customer LTV and customer acquisition costs. In that case, they'll want a big stack of cash to start buying up customers whereever cost < LTV.


Maybe they did nail down the lifetime value of a customer. But I doubt they nailed down the acquisition cost.

It's not like you can pay to have your customers refer more friends.


Its not as hard as you might think. I'm sure Patrick (patio11/bingocardcreator.com) knows the cost of acquisition for 1 customer. If you're good with AdWords, its pretty doable.

Anecdotally, I've heard Amazon shoots for $23. Thus they'll put basically unlimited money into any system bringing in customers for < $23.

You can run into a problem of volume though, i.e., you overfish the pond. Then you'll need to find new sources of customers (e.g., Facebook ads if you've only done SEM).


George literally stole the words out of my mouth. $12 to $15 via AdWords, incidentally.

Unhappily for me, I'm capable of saturating all of Google's advertising inventory conveniently available at $15 per customer. (Its sort of like oil: the more you are willing to spend, the more exists in the world. I guess if I were an environmentalist I would describe my current state of affairs as Peak Bingo, but with some sustained effort into AdWords I could probably locate more sources of customers between $15 and $30, or alternatively in different mini-verticals.)


Thanks for sharing your customer acquisition cost. Do you ever buy traffic from anywhere else or are you happy with the volume from AdWords?

BTW, still chuckling at Peak Bingo. Well put.


Today is November 25th. A click on November 25th turns into a purchase by, on average, November 27th. I have to pay Google on December 20th, with a credit card. My next statement date is January 7th, and my payment is due somewhere around January 20th. So, basically, if I get N clicks today, I get $30 two days from now and have to pay $15 two months from now.

This is a long way of saying that, while I'm happy with my volume, I'd be more happy with, oh, enough volume to hit the limits on my credit cards. In fact, I'd avail myself of pretty much every source of credit less odious than juice loans from yakuza or opening an account with CapitalOne.

I have paid for advertising elsewhere. The main issue is that a) Google has a de-facto monopoly on it in no small part due to the fact that b) their competitors s<%= "u" * (10 10) %>ck. Microsoft, for example, takes every bit as much work to get right as AdWords does, but you have to do it within their application, and they have less than one tenth the inventory Google does. To add insult to injury, it is at higher prices. I got a note in the email from them that my credit card had expired and could not bring myself to logging in to give them the updated credit card number, that is how useless they are to me.


That makes sense. Since you seem to have found your own quarters-to-dollars machine I've been wondering why you aren't exploiting every possible source of profitable traffic. Sounds like a case of diminishing returns.

I'm surprised prices @ Bing are higher, I'd assumed lower volume would mean lower competition and thus lower prices. But I definitely understand how the volume they can deliver isn't worth the time spent optimizing their system.

Thanks for elaborating.


Sure. With adwords you can know the COC. But not with referrals.


Perhaps not, but you can calculate the chance that a given customer will refer a friend, and factor that into their lifetime value.

Even more interesting, you can see which actions are predictive of referring friends (e.g., leaving a comment on the suggested features list). You can use the same strategy to predict the conversion rate from free to paid.


A referral effectively reduces the cost of acquisition, and you can calculate the extent to which it does that.

I think Dropbox is valuable enough to become ubiquitous but one imagines they need to grow to a certain size before such a feature exactly is rolled into a version of one of the big operating systems. Not that what they've done isn't technically difficult of course, but it just seems like something so valuable it might be on a Chrome wishlist.

Cool thing if the guys who make the software are reading this - started a new job earlier this year at a mostly non-software company managing a few development projects. I doubt most of my colleagues are aware of this startup culture or have heard of .NET much less Y Combinator.

First week "You've got to see this program we have the sales team using, called Dropbox... its tremendous there's about a thousand things we can use it for". Not only are they using it its their "we're showing this off to the new guy" thing.


It's unlikely that one of the big operating systems would come forth with a feature that worked with all of the other big operating systems as well.


Marketing? They could be huge if more people knew about 'em.


I'm betting Dropbox will be the biggest YC exit for quite some time.

Please stop jinxing them.


Dropbox is really awesome. I'm very impressed with how well they execute. Lots of companies big and small have offered the same basic service, but nobody has built a product nearly as good.


What about Live Mesh? (When assumed that all your computers run windows). As I see it, there is basically all the functionality of Dropbox, plus 5GB free space, ability to sync several folders, and remote desktop functionality.


I believe Live Mesh has an OS X client now. I tried it (on both OS X and Windows), and while it has most of same basic functionality as Dropbox, I found the interface off-putting.


"1.3 million gigabytes" - is that correct? If it is .. wow!


"And Dropbox ... says it will offer tools for corporate collaboration in a more formal fashion early next year."

Any Dropbox folks here who could comment on what those tools might be?


It seems that this article is inaccurate:

http://www.techcrunch.com/2009/11/24/dropbox-sequoia-funding...

"Dropbox did close a Series A funding round, but it was for $6 million, and it was back in October 2008. And it was led by Sequoia, not Accel (though Accel did participate in the round)."


Grats guys! Just out of curiosity, how did you come up with $7,252,763? Everyone knows its good luck to end with a 4. You could be $1 away from an IPO there.


Agree, Dropbox is amazing. Cheap version control for the rest of us. Made my USB drives useless.
