AINN-P1 on VHH affinity maturation, vs 0.68 for finetuned ESM2 — parity-plus at 3.9× fewer parameters.
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.
Validated targets with sub-nM leads
Single-digit picomolar campaigns
Molecules experimentally tested in wet lab

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.
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.
IgG, Fab, scFv, VHH, bispecifics. Picomolar leads on IL-13, IL-25, IL-36R, TSLP.
De novo small molecules, PROTAC design, scaffold hopping. CRBN neosubstrate selectivity panels.
GLP-1 analogs, cyclic peptides, stapled therapeutics. 3.2M-peptide screens with 90%+ accuracy.
CAR construct optimization, activation prediction, persistence modeling.
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.

Methods, benchmarks, and validation studies published across antibody, protein-language-model, and chemistry venues.
Founders bring sixteen-plus years of structure-free affinity modeling and protein engineering to the company founded in 2021 — not a ChatGPT-era pivot.

Our team brings together decades of experience in protein engineering, cheminformatics, machine learning, and pharmaceutical commercialization.
"We report what we found, not what we hoped. We publish failures alongside successes, disclose uncertainty honestly, and correct the record when we are wrong. Metrics are earned, not marketed."
