Tomorrow's medicines should be designed with the precision and scale of modern engineering. I'm thrilled that @chaidiscovery has raised a $400M Series C at a $3.8B valuation from @IndexVentures @kleinerperkins @sequoia @_DimensionCap to accelerate progress towards that goal.

Our bet from day one: this is how most future drugs are going to be discovered. My co-founder @Mattmcpartlon1 and I sat down with @gradypb from @sequoia to talk about how drug discovery is becoming an engineering discipline

To date, finding a drug has been a process of guess & check… screening millions of molecules hoping one binds. @chaidiscovery is changing the paradigm… describe the molecule you want, and the model designs it. @joshim5 and @Mattmcpartlon1 took antibody hit rates from roughly

Great to sit down with @BrianSozzi on Opening Bid Unfiltered in New York to talk about why AI in drug discovery is finally moving from promise to deployment. For years, expectations outpaced reality. That’s changed. What’s possible in molecular design today wasn’t possible just
