Biossil raises $153M, hits unicorn with OpenAI backing

Biossil, a Toronto startup that buys and revives failed drug candidates using AI, just raised $153 million, pushing its valuation to $1 billion. OpenAI's Startup Fund led the all-equity round, with support from Founders Fund and other investors. Biossil plans to use the funding to expand clinical trials and buy more drug candidates, accelerating efforts to turn AI-derived insights into real treatments.

Why it mattersTech companies are betting that AI can rescue drugs that failed in traditional pharma pipelines, and this funding signals growing confidence—and competition—in automated drug discovery. The move could speed up treatments for complex conditions like cancer or Alzheimer's.
