Y Combinator Backed by Y Combinator

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

Biology

We work with a network of biology and life science postdocs to create realistic scientific tasks and solution trajectories in the style of benchmarks like LifeSciBench, GeneBench-Pro, and BioMysteryBench.

About us

We're three ex-Stripe staff engineers that have built financial infrastructure powering millions of businesses.

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