A dad who cracked it.
A son who could build it.
LivingLean was built by a father and son — one who lived the problem for 43 years, and one who knew how to build the answer.
Rob (left) and Zachary — founders of LivingLean.
It started at the kitchen table, not a boardroom.
Rob spent 43 years trying everything to lose weight — and finally did it, by talking to an AI every day about what he ate. His son Zachary had been building with AI for years.
When Rob showed him what had actually worked, they saw the same thing at the same time: this wasn't a diet. It was a coach. So they built it — together.
Rob
Rob is the reason LivingLean exists — he lived the 43-year struggle and the turnaround himself, and he still talks to his coach every day. A serial entrepreneur who has built and sold companies before, he handles the story, the strategy, and keeping the mission honest. Off the clock, you'll find him on the golf course.
Zachary
Zachary owns the build — the app, the AI, the coach you actually talk to. An engineer at Duke's Pratt School of Engineering, he has been building with AI for years and is deep in Duke's entrepreneurial scene. When he's not shipping code, he's at the gym, out with friends, or on the golf course with his dad.
“I watched my dad finally get the weight off after a lifetime of trying — that was real. I've been building with AI for a few years, and I love the work. And honestly, most of the world is bracing for AI to go wrong. I wanted to build something AI-native that actually helps people. This does.”— Zachary
Accountability without judgment — built by people who lived it.
LivingLean is a family effort — Rob's twin sons, Carson and Dylan, pitch in too.
