Design binders for your target.

Francis is our in-house generative model for antibody and nanobody design. Academic labs submit a target and get back designed, developability-scored binder sequences to express and test — free. In return, you tell us how they did.

Why it might work on your target

Trained on millions of natural antibody sequences — designs land in the real repertoire, not off-distribution.
Antigen-aware CDR design, conditioned on your target (and your epitope, if you give one).
Every design is screened for developability and scored against the natural (OAS) baseline before it reaches you.

We'll keep you@company.com posted.

Francis is open to academic labs right now while we validate in public.

For commercial use it's a licensing conversation — those take real work on both sides. The fastest way to start is to just see it run on a target you care about.
