About Petrichor

YC company profile

Wet lab infrastructure that turns AI experiments into training data.

Real biology requires a wet lab, and building one takes years and a team most AI companies don't have. Petrichor runs their experiments at scale and sends back the dense, clean data their models need to learn from.
