Today we're launching Petrichor (YC F26), a wet lab for frontier AI labs

Petrichor (YC F26) launched as a wet lab service for frontier AI labs, running biology experiments in parallel and returning data from every step, the company announced on X. Models submit experiments directly through Petrichor's Python library, writing each experiment as a job, and customers own all resulting data, which Petrichor says it never shares or trains on. The launch drew a public challenge questioning the founders' lack of hands-on experiment experience and whether customers would pay $5,000 to $10,000 for a first-time run.

Petrichor on X: "Today we're launching Petrichor YC F26 , a wet lab for frontier AI labs. We run experiments in parallel and return the data from every step." We think biology is the most important field AI will touch and at the same time the most data-constrained one. Frontier labs are all going after it and need far more experiments than they can run themselves, so we run them. Models use the lab directly through our Python library, writing each experiment as a job and submitting it themselves. We capture as much data as we can from every run, so labs end up with the best possible training data for improving their models. Customers own all the data we produce for them, and we never share it or train on it. If you work on biology at an AI lab, email me at email protected Why would someone choose your CRO over another? You have no experience actually doing experiments and no way your cost is less. People are supposed to pay $5000 or $10,000 for you to run an experiment for the first time in your life and we are supposed to trust the results.
