AI-guided antibody Development

Make your complex biologics happen.

Cradle helps scientists get to clinically viable candidates that meet every property in your TPP, with fewer programs lost along the way.

The next generation of biologics needs more than affinity

Your team is being asked to deliver biologics with binding profiles, formats, and developability constraints that single-property optimization can't reach. Bispecifics that hold both arms together at temperature. ADCs that survive payload conjugation without aggregating. Multispecifics with humanness, low immunogenicity, and clean PK. Hard targets where binding is only step one.

From hit to clinical-ready antibody, in fewer rounds.

Fewer rounds

Reach your full target product profile 2-12x faster.

Cradle optimizes binding, stability, developability, and manufacturability in parallel — not sequentially. Bring immunogenicity, toxicity, and functional assay data into the loop from round one.

Better antibodies

Explore sequence space your intuition wouldn't reach.

Diverse panels of candidates with non-intuitive mutations rational design and display campaigns wouldn't surface. Sequences close to germline, free from immunogenic motifs and PTM liabilities. Across VHH, scFv, Fab, IgG, bispecifics, and antibody-drug conjugates.

Built for biologists

An intuitive workbench for antibody scientists

Scientists run campaigns directly through the UI. Computational teams extends the platform via API with their own predictors and scoring. Your sequences and model weights stay yours.
