Y Combinator Backed by Y Combinator

We build expert-level training data, benchmarks, and reinforcement learning environments for frontier models, starting with biology.

Biology

We work with a network of biology and life science postdocs to create realistic scientific tasks and solutions, similar to those in LifeSciBench, GeneBench-Pro, and BioMysteryBench.

Who we are

We're three ex-Stripe senior engineers.

Contact us if you're training models that need to reason about the life sciences.
