AI Creates New Viruses, Building AI for Healthcare & Moats in Healthcare IT | Lightwork

Claire Zau is joined by Dr. Brenton Fargnoli, a physician and partner on Lightspeed's healthcare team, to unpack the AI-designed bacteriophage story making headlines this week. Stanford and Arc Institute researchers used a genome language model to design nearly 300 candidate phage genomes and landed on 16 that worked, a cocktail able to overcome resistance the natural phage couldn't beat on its own. The phages only infect E. coli, not human cells, and a scientist still has to synthesize and test every design in a lab.

From there, Brenton and Claire get into what they believe it takes to build a vertical AI company in healthcare right now, from finding the right wedge to surviving the moment an incumbent like Epic decides to build the same feature natively. They cover why founders are seeing faster adoption than past software waves, what separates a real data or workflow moat from a feature a platform can copy, and what Brenton looks for in a team before backing them.
