Q&A: Foursquare CEO Dennis Crowley on What He's Learning From Twitter and What's Next

Foursquare, about to celebrate its third birthday, is big but not huge. It has signed up 15 million users, hired over 100 employees and now boasts several million check-ins per day. That is impressive work for three years, but it must keep growing.

To do so, Foursquare co-founder and CEO Dennis Crowley says the company is in the process of redesigning its mobile app for a broader audience, disassembling it and trying to put its features back together in a way that’s more useful and interesting. It has also launched new features on its Web site, such as the neat and powerful “Explore” tool, which can help you find cool places to visit in your neighborhood or in an entirely new city.

As Twitter realized a few years ago, Crowley says Foursquare is seeing a big chunk of its growth from people who want to use parts of Foursquare, but not necessarily broadcast to the world. That means building a service that’s useful to more casual users, and not just early Foursquare diehards.

I recently sat down with Crowley at the company’s brand new, roomy headquarters in New York City, for an idea of what’s next. Here’s a lightly edited transcript of our chat.
