Xaira Therapeutics

Xaira Therapeutics is an integrated biotechnology company that brings together advanced AI research, expansive data generation, and robust therapeutic product development to transform drug discovery. Co-founded and incubated by ARCH Venture Partners and Foresite Labs, Xaira's computational core is built on foundational work by Nobel Laureate Dr. David Baker and his team at the Institute for Protein Design at the University of Washington, leveraging AI to design entirely new proteins from scratch. The company develops AI capabilities ranging from fundamental computational methods to molecule design and clinical development, underpinned by a robust data platform generating multidimensional datasets spanning molecular to human scales. In 2026, the company launched X-Cell, its first virtual cell model trained on the largest-ever genome-wide perturbation dataset, with software and model weights released on GitHub.
