Polyphron raises $20 million in seed funding to test AI's biological predictions

Polyphron announced $20 million in seed financing to build a verification layer for AI-driven biology—a system where models can test predictions and learn against living human biology. The company argues that AI's ability to generate hypotheses, therapeutic candidates and experimental designs is advancing faster than the ability to test them. Its bet is that tissue offers the fastest, cheapest, most parallelizable testing ground that still contains the biology that matters.
