Gavin Cotter
Gavin Cotter is the founder and CEO of Koala Health, a Boston-based digital pet pharmacy that delivers chronic pet medications through a mobile-first platform built to work directly with pet parents and their veterinarians. An MIT-trained mechanical engineer turned operations leader, he cut his teeth scaling PillPack's pharmacy operations before Amazon acquired it, then reassembled a core PillPack crew in 2021 to do for animals what PillPack did for people: make managing medications boring, easy, and reliable. Koala has since expanded to all 50 states and raised a $20M Series B led by Valspring Capital in 2025.

George Zachary is a General Partner at CRV (Charles River Ventures) and one of Silicon Valley's most storied venture capitalists, known for seed-stage bets on Twitter, Yammer, and PillPack. A Greek-American MIT graduate who once helped build the Nintendo 64 at Silicon Graphics, he pivoted from consumer internet to bioengineering after a near-miss cancer scare in 2015 - writing more diligence on his first biotech deal than in the prior decade combined. He deploys capital guided by a single question: does this founder need - not just want - to build something big?
