CellType

CellType is a Y Combinator W26 biotech startup building an 'agentic drug company' that simulates human biology to de-risk drug discovery. Founded by Yale professor David van Dijk and ML engineer Ivan Vrkic, it pairs Cell2Sentence, a 27-billion-parameter biological foundation model built with Google DeepMind, with AI agents that run the discovery pipeline from hypothesis to compound screening. The goal is to replace animal models and cell lines with computational simulations of human biology and cut preclinical failure rates.
