General information

Xaira Therapeutics is a biotechnology company that uses artificial intelligence for drug discovery and development. Its core product, X-Cell, is a virtual cell model that predicts the outcomes of genetic perturbations. The company is led by CEO Marc Tessier-Lavigne and is based in South San Francisco, California.

Xaira Therapeutics launched with more than $1 billion in capital. That is an unusually large amount for a new biotech company, and it lets Xaira fund both its AI research and its drug pipeline without needing to raise money again soon. Historically, the median salary is ~$162,500. Xaira Therapeutics is an H-1B sponsor.1
