AI FOR SCIENCE · ON THE RECORD
AI Proteins
Designs miniproteins from scratch with AI, then makes and tests them in a high-throughput lab, as drugs that are smaller than antibodies; its own pipeline starts in oncology.

- 2026-10-28BioGeometrySeries A+ · not disclosed; the A series to date tops $100MBuilds generative models for biology: GeoFlow, an all-atom model that predicts the structures of proteins and their complexes and designs binders, and GeoCell, a virtual-cell model of how cells' gene expression responds to genetic and drug perturbations. An automated lab expresses and tests the designs and feeds the data back. It designs antibodies, vaccines, peptides and enzymes for partners and its own pipeline, including synthetic-biology products.
- 2026-09-24BigHat BiosciencesSeries C · $75MDesigns antibodies with machine learning tied to a fast automated wet lab (Milliner) that makes and tests designs; its lead drug BHB810 is in the clinic.
- 2026-08-11Aureka BiotechnologiesSeries B · $100MDesigns antibodies with its own biological foundation model, AuraIDE (released in open form as OpenDDE), trained and retrained on data from its own single-cell functional screens.
- 2026-07-14Chai DiscoverySeries C · $400MBuilds AI models that predict how molecules bind and design antibodies from scratch, and licenses them to drugmakers as software.
- 2026-06-17MoleculeMindSeries A (extension) · A-series cumulative total over US$100 millionAI protein structure prediction and design (MoleculeOS, MMFold, MMDesign) sold to drugmakers and industrial-enzyme users, with a few in-house early programs.
- 2026-03-20Helixon (Earendil Labs)Round (unnamed) · $787MAI protein modelling plus high-throughput experiments to design antibodies, especially bispecifics, which it licenses to Sanofi and Genentech and develops in-house.
