Alex Karnal - The Trillion-Dollar Health Revolution - [Invest Like the Best, EP.468]
Show notes
My guest today is Alex Karnal. Alex is the co-founder and managing partner of Braidwell, a life sciences investment firm he built after spending 15 years at Deerfield Management. The frame we use throughout the episode is the health stack. Alex talks about how most of the diseases that will claim most of our lives are already addressable with medicines that exist today. We work through the five layers of what a defensive health strategy looks like, why GLP-1 medicines represent the first commercial proof that people are ready to be proactive about their health, and why PCSK9 inhibitors may ultimately be the more important drug class even though they get far less attention. We also get into the science and business of drug discovery itself — why most of the published literature that AI companies are training on cannot be replicated, what it would mean to have a truly agentic scientific lab running 24 hours a day, and why Alex believes we are now on a deterministic curve toward scientific superintelligence in biology.
