The company's most popular open source project, also called sentry, has over 31K stars and lets users monitor and fix crashes in real-time. The server is in Python, but it contains a full API for sending events from any language, in any app.

Sentry has raised $217M from investors including Accel, NEA, and Bond.

In this episode, we talk with David about starting Sentry before open source business models were mainstream, how he's adapted as a leader holding the CEO and CTO seats at different points in time, and his candid advice to open source founders (particularly first-time founders) starting out today.
