Why Gyms Won't Buy Your Fitness App

Max Cotton, retired professional MMA fighter and founder and CEO of Vor, explains why he spent five years building an AI exercise programming engine that deliberately avoids large language models. The $40,000-in-tokens story, the lawyer test for trusting AI outputs, how PureGym founder Peter Roberts came to join the board and fill the round, Vor's two pivots, and what going 2-2 in the cage and collapsing 87.1 miles into a 100 mile run taught him about the harder discipline of building a company. First episode of the new Healthier interview series.

What's Actually Going On Inside You (AI Can Now Tell You)

Hamish Grierson, co-founder and CEO of Thriva, gives a screen-share tour of how the UK blood-testing company turns your results into action. He walks through Compass (three tests a year, chosen for you), how Thriva benchmarks your markers against people your own age and sex, the difference between being 'in range' and optimal, and how blood data now sits alongside your Oura, Garmin and Whoop metrics in one Healthspan dashboard. The finale is Thriva's new Health Assistant, an AI advisor that has your blood, sleep, movement and goals as context, demoed live on cholesterol and an Omega-3 dinner.

The Best Vibe-coded Health Setup We've Ever Seen

He did it as a side project, with prompts, while running a startup and raising three kids.
