We built Strava because we missed training together. It started as a way for two friends to share workouts across cities. Now 120 million people use it.

Segments changed everything. The moment people realized their daily commute was a leaderboard, indoor trainers gathered dust.

If it's not on Strava, it didn't happen. We didn't invent that phrase. Our users did. That's when we knew we had something beyond a fitness app.

We have GPS data from 120 million people in 195 countries. Cities pay us to tell them where cyclists actually ride versus where they built the bike lanes.

Our heat maps accidentally revealed secret military bases. That was a bad week. But it proved something: our data is more detailed than anything governments have.
