Sepal AI

Sepal is a data research company on a mission to advance human knowledge and capabilities through safe AI.

We partner with the world’s leading AI labs and enterprises to help their models get better at the tasks people actually want them to do.

We’ve built a Cloud-Native Agent Dataset Factory which turns the process of generating evaluation and training data from manual, inconsistent, and labor-intensive into something automated, standardized, and scalable.

Sepal AI was founded in 2024 by engineers and operators from Vercel and Turing. We went through Y Combinator, raised several million dollars from leading investors, and already count multiple Fortune 500s and top AI research labs as paying customers.
