We're an ~80-person team (SF, Barcelona, Budapest, and remote) with a mission to help developers build software quickly and painlessly. We help tens of thousands of developers find and fix errors faster. Our backend handles billions of errors with low latency and high reliability. Our front-end allows developers to discover and drill down across millions of errors in real-time. Our open source libraries are used by some of the best engineering teams in the world, including Twilio, Affirm, Salesforce, and Twitch.
