AI-Native Drug Discovery

Antibodies at
picomolar precision,
in weeks.

AINN-P1, our protein foundation model, has produced sub-nanomolar leads on 15 of 40 validated targets — 6 at single-digit picomolar — across 2,872 wet-lab tested molecules.

Our Mission

We are rebuilding drug discovery from the sequence up — making therapeutic design computational, honest, and partner-ready.

Most AI drug-discovery platforms stop at a demo. We go further: our models are trained on industry-grade proprietary data and validated at every stage by wet-lab experiments, so what we deliver to pharma partners is already de-risked.

The result is a different kind of handoff — not a screening score, but a program: patentable, validated, licensable, and ready for your development pipeline.

Sequence-first design Protein foundation model, no 3D structure required
Wet-lab validated Every lead confirmed experimentally
Patentable IP Clean freedom-to-operate on novel compositions
Licensed to partners Programs ready for pharma development
Platform

SentinusAI® — a protein foundation model that produces binders, not scores.

Built on AINN-P1, SentinusAI combines sequence modeling, affinity prediction, and generative design into a single pipeline. Trained on proprietary assay data and continuously benchmarked against wet-lab outcomes.

The Science

Published, benchmarked, and reproducible.

AINN-P1 outperforms finetuned ESM2 on leave-program-out AUC for VHH binders (0.81 vs 0.68) at a fraction of the parameter count. Our methods are peer-reviewed, our benchmarks are external, our failures are published alongside our successes.

0.81

Leave-program-out AUC

AINN-P1 on VHH affinity maturation, vs 0.68 for finetuned ESM2 — parity-plus at 3.9× fewer parameters.
