Celine Halioua is the founder and CEO of Loyal, a biotech company developing medicine to help dogs live longer and healthier lives. And dogs are just the start - Celine thinks Loyal could one day do the same for humans. She takes us inside what it’s like to build a biotech company from scratch. We talk through how Loyal’s longevity drugs work, the process of getting FDA approval, her biggest mistakes as a founder, how to approach building in a new market, lessons learned failing to raise her Series B, why rate of growth is all that matters in hiring, and almost not starting the company in the first place.
