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.
