Announcing the Stack Overflow Series A Financing

We’ve been growing quite a bit lately: We’re now #709 on Quantcast. In less than two years, we’ve grown from zero to 7.1 million unique people visiting our network of sites every month.

Quantcast visits chart for Stack Overflow Network

We’re now #709 on Quantcast. In less than two years, we’ve grown from zero to 7.1 million unique people visiting our network of sites every month.

This growth makes us happy, because it means millions of people are getting quality answers to their questions. As Jack Marchetti describes it, “It’s a Q&A site where the right answer isn’t buried on page fifty, it’s almost always at the top.” Here’s what a few random people on Twitter said recently:

Stackoverflow is such a valuable service. Lately I have observed developers don't search Google, they go directly to Stackoverflow!

has nuttin but love for these people rock ;-) quick answers fast ...

Stackoverflow is dangerous as its faster than thinking

StackOverflow is totally delivering for me today...

In Jon Stewart voice... Oh Stackoverflow, how I love thee... Lots of good questions and answers.

The more I do with javascript the more I find the most useful google search results are on is replacing google for me as the goto for nerd questions: much higher signal to noise ratio.

The problem is that, golly gee, why just programmers? Surely there are people out there in different professions — you know, candlestick makers, robotics engineers, and designers of favicons — who could use a site much like Stack Overflow to get answers to their hard questions. And some of these people must have questions, themselves, about candlesticks, positronic brains, and teeny tiny pixels, and they must be frustrated when they go to a bulletin-board site and the right answer is buried on page 50.

So we created Stack Exchange to bring the technology behind Stack Overflow to a much wider variety of sites. We tried charging for Stack Exchange, and that didn’t work so well. So we asked ourselves, “How would the people of 1999 solve this problem?”

And the best answer we could come up with was, let’s make the damn thing free, and get some VC somewhere to pay for it.

The first VC we asked thought this was a pretty good idea. So did the second, and the third, and in fact I spent two weeks driving around Sand Hill Road and pretty much all of them thought that this was just a BOFFO idea.

One of them, Brad Burnham, suggested that we don’t hard code our revenue model too early. If the platform creates value for a lot of people, he told us, we’ll have plenty of opportunities to make money that actually make the site better.

That reminded us of Stack Overflow Careers, where great programmers can leverage all the good work they do on Stack Overflow to get great jobs. It gives us an opportunity to make money and it actually makes the site better.

Hey Presto!

THUS: I’m excited to announce that Stack Overflow has raised $6MM from a group of investors lead by Union Square Ventures and including Ron Conway, Chris Dixon, Caterina Fake, Naval Ravikant, Nirav Tolia, Joshua Schachter, Micah Siegel, and Bob Pasker. Brad Burnham from Union Square Ventures will join the board of directors.

That’s an amazing list of investors. Bernard Lunn described Union Square Ventures as “The Best of the Valley in New York” — right now you’d be hard pressed to find anyone who didn’t think they’re the best VC in the city if not the best VC period. In addition, we have #1, #2, #20, and #22 on Business Week’s list of the top 25 angels in tech. All-in-all, I’m in awe of this group of people we’ve brought together.

We’re also announcing the formation of a board of advisors for Stack Overflow, including some of my favorite thinkers, who have already helped us immeasurably as we built the company: Clay Shirky, Anil Dash, Marco Arment, Miguel De Icaza, Rich Skrenta, and Micah Siegel.

The money we’ve raised means that, for the next ($6m / monthly burn rate) months, we can take on new projects, hire new people, and build new expert Q&A sites on a wide variety of new topics. Instead of opening sites in exchange for money, we’re about to launch a new, democratic system where anyone can propose a Q&A site, and, if it gets a critical mass of interested people, we’ll create it.

We do need to hire a few people right away. We need top notch programmers (mostly in the office in New York). We need a world class VP of Sales and more salespeople. I need a sidekick, someone to help me with, you know, CEO stuff. The only way to apply for these jobs, of course, is to make a CV on Stack Overflow Careers and email the URL of that CV to

The Loop #2: Understanding Site Satisfaction, Summer 2019

We’re excited to share research highlights about the work we’ve been doing to understand how satisfied people are with Stack Overflow. We’ve been working hard to explore what users like best about Stack Overflow and what their top pain points are, with the goal of improving the overall experience of using the site. To this end, we’ve launched a site satisfaction survey, in which we continually survey users about their experiences using Stack Overflow.

The Loop, May 2020: Dark Mode

We received a bunch of requests to share how we use our feedback framework on specific features. We got excited about this, and given that we just released Dark Mode (and “Ultra Dark Mode”), we thought this was a great opportunity to show how we arrived at our solution.
