# 31 He wants to save your pet with cryo - The Kai Micah Mills interview

When you give a child a pet, you also expose them to death—since most pets pass away long before their owners. But what if we could cryopreserve Buddy or Tiger, and bring them back from suspended animation once we have a cure for what ended their lives?

Kai Micah Mills is a pioneering figure in radical life extension and biostasis. As the founder of Cryopets, he is leading efforts to make cryopreservation accessible for pets, with aspirations to extend these technologies to humans. He left high school early to pursue entrepreneurship, becoming a tech entrepreneur in his teens. A Thiel Fellow and co-founder of CryoDAO and HydraDAO, Kai is deeply involved in decentralized science initiatives aimed at advancing longevity research.
