About us

We're based in San Francisco with physicians across the country. Our team has built clinical-reasoning RL environments for AI labs, evals for surgical robotics cameras, and robust segmentation masks for geometry detection.

We're a team researchers, engineers, and physicians from Jane Street, WashU Med, Moon Surgical, NASA, Duke, and Eko Health. We're flexible in the data we can offer — including bespoke annotations for niche targets.
