Overview
Absci is a generative AI drug creation company that combines large-scale AI-driven antibody design with an integrated wet-lab validation platform. The Absci Drug Creation Platform uses proprietary zero-shot generative AI models — trained on billions of protein sequences — to design de novo antibodies with desired binding, selectivity, and developability properties, then experimentally validates candidates at scale using high-throughput cell-free expression and binding assays. Pharma and biotech partners use Absci's platform through collaborative drug creation programs targeting oncology, immunology, and infectious disease. A landmark 2023 Nature paper demonstrated that Absci's AI designed functional antibodies from scratch — with no starting sequence — in a process validated by wet lab experiments, marking one of the first demonstrations of zero-shot generative AI antibody design. Absci's core differentiation is the closed-loop integration of generative AI with experimental validation. The company's SoluPro cell-free expression system can produce and screen thousands of AI-designed antibody variants per week, generating training data that continuously improves the generative models. This data flywheel accelerates both the AI platform and partner drug programs simultaneously.
