CellType is an AI-driven drug discovery company building what it calls "The Biological World Model" — foundation models and autonomous agents that simulate human biology to predict drug responses in human systems before clinical trials, reducing reliance on traditional preclinical models such as mice and cell lines. Its core technology, Cell2Sentence (C2S), teaches large language models to understand cellular biology by converting single-cell gene expression data into a text-like format that models can interpret, and the company reports using it to discover and validate a novel cancer treatment signal targeting tumor immunogenicity. A Y Combinator (Winter 2026) company based in New York City, CellType works with large pharmaceutical partners and currently operates as a B2B research and drug-discovery platform rather than a public developer API.
