About the company
Terra is the health operating system. We make it easy for developers and AIs to build on health data. hundreds of wearables, sensors, labs, and health apps — connected, normalized, and made intelligent through a single platform. 1,000s of developers and AI labs build on Terra today. we process 15+ billion health data events per year. and we are just getting started.

The health OS
Health data is fragmented. every device, every app, every sensor speaks a different language. we built the health OS to solve that — a full-stack platform that turns raw, messy, siloed health data into something developers and AIs can reason over, build on, and ship with. Terra was founded in 2021 and operates from London, San Francisco, and South Korea. We are funded by Y Combinator (W21), General Catalyst, Samsung NEXT, NEXT Ventures, and many of the world's finest investors. We are a team of engineers, researchers, builders, and designers. we hire people who get things done, think from first principles, and learn ferociously. we default to yes. we ship fast. we hack. we build. we don't do bureaucracy.
