Kai Micah Mills | Founder, Cryopets

Cryonics has long lived on the fringe — dismissed as science fiction or Silicon Valley fantasy. But a new generation of founders is treating it as an engineering problem.

Kai Micah Mills, founder of Cryopets and Thiel Fellow, is building a company designed to preserve pets in a vitrified state immediately after death, with the long-term goal of revival once medicine advances far enough.

Behind the polarizing headlines is real scientific progress, serious capital, and a growing customer base that looks far more mainstream than most people would expect. In this conversation, Micah explains the breakthroughs already happening in cryopreservation, why thousands of pet owners have joined the waitlist, and why he believes the first practical step toward radically extended life may not begin with humans — but with the animals we love most.

You dropped out of high school, started building Minecraft servers, and sold your first company for six figures at just 16. What did those early experiences teach you about building companies and taking risks at such a young age?

Dropping out of high school is the single best decision I have made in my life. Minecraft was the launchpad that taught me how to be an entrepreneur. I was able to experience managing dozens of employees, thousands of customers, and large amounts of money while my peers were still in high school. Beyond just learning how to bootstrap and operate companies from scratch, I learned that isolation will force you to discover who you truly are, school is a scam, and to always, always, bet on yourself.

Cats are living longer, but the drugs for age-related disease have not kept pace. The Cat Health Company, a clinical-stage biotech, has three drugs in trials and 11 more preclinical candidates, and has out-licensed its first therapeutic. Co-founder and COO Alexandru Bacita explains why cats compress the drug-development loop, how the company targets muscle loss and kidney disease first, and why the route to longevity runs through veterinarians and pharma partners.

Elias Weiss Friedman | Founder, The Dogist Company

Elias Weiss Friedman spent a decade turning street photography into The Dogist, one of the largest dog-focused audiences online. Now he's testing whether that trust extends to physical products, starting with Vitality, a vet-formulated antioxidant chew built with Dr. Angela Rollins. He talks about the discipline of brand extension, the operational learning curve of a first physical product, and what a decade of stopping strangers on the street taught him about people, not just dogs.

Sarah McLean | Co-Founder & CEO, Big Damn Dog Co.

A joint supplement label that stopped at 60 pounds sent Sarah McLean looking for a product that did not exist. Big Damn Dog Co. is the bootstrapped answer: giant-breed formulations, dosing built for 120-pound dogs, and a customer list the founders still call by phone. Six months after launch, its Gravy Blend already accounts for roughly 40% of joint supplement sales.
