We are excited to announce that StumbleUpon has just reached 20 million members! We’ve come a long way over the last few years, and I wanted to thank all of our Stumblers for helping us get to this point. What started as a Firefox extension has now become available on any browser, as well as iPhone, iPad, and Android devices. Our userbase – which has more than doubled since last year – now stumbles more than 1,000 times per second at peak times of the day. When I recently came across a magazine clipping from 2003, it struck me that we now serve as many stumbles in a single hour as we did in our first year of existence! So it’s very exciting for us to reach such a milestone, all from the simple idea of “click a button, find cool stuff.”

Key milestones along StumbleUpon’s path to 20 million users.


Along the way we’ve also done some pretty amazing things with your help, including getting a short story discovered that’s now being made into a moviefeeding Kenyan refugees, helping people fall in love across thousands of miles and even helping one couple get engaged. Talk about serendipity.

On behalf of the entire SU staff, I’d like to thank our community for letting us be your guide to the web. Your collective curiosity and passion for discovering new and interesting things is what keeps us going, and we will continue to focus on making your experience as good as possible. :)
