Today we’re announcing we’ve raised $20M in seed financing led by @QuietCapital , with participation from @GradientVC , @haystackvc and @CompoundVC and other amazing folks to build the verification layer for AI-driven biology. We are also delighted to be welcoming @vqctran who is joining us from @GoogleDeepMind as a co-founder. AI is not going to cure all diseases without a verification substrate - a scalable environment where models can test predictions and learn against living human biology. AI is becoming increasingly capable of generating biological hypotheses, therapeutic candidates and experimental designs. But generating ideas is advancing much faster than our ability to test what those ideas will actually do in human biology. Existing systems force a tradeoff: the most biologically relevant approaches are slow and expensive, while faster in vitro and computational systems often lack the fidelity needed to capture human response. Polyphron’s bet is that tissue is the fastest, cheapest, most parallelizable verification substrate that still contains the biology that matters and we believe the path to biological superintelligence runs through closed-loop interaction with these living and simulated human systems. Thank you to @axios for covering the announcement. Link to our new website in the thread.

Still amped up from a electric @BoostVC LP Day 🔥🔥🔥 Our goal for the day: have LPs get a glimpse of the future we get to see every day. @DougBernauer shared lessons from 12 years at @SpaceX and how he’s now finishing the multiplanetary mission w/ @RadiantNuclear (and his recent $750m contract!). ☢️ Three bio founders pitched on eliminating genetic diseases, rejuvenating the brain, and personalized cancer vaccines (and the fastest in history to do it!). 🧬 Then @TimDraper on why first-check investing, saying YES first, is the key innovation. 🥇 Will be tough to top this one next year. Thank you to everyone who came out! 🫶
