Back in 2024, Sam Altman declared that AI would produce "a billion-dollar company by one person" — something unthinkable without AI. At the time, plenty of people laughed it off.
Well, here's the proof.
The New York Times profiled Matthew Gallagher, a guy in LA who spent $20,000 and just two months building Medvi, a telehealth site selling GLP-1 weight-loss meds, out of his own home. Revenue in year one: $401 million. This year, it's projected to hit $1.8 billion — and his entire full-time headcount is his brother.
Breaking down his "AI tool stack"
Nothing in here is black magic:
- Writing code: ChatGPT, Claude, and Grok, used together;
- Ad creative: Midjourney for images, Runway for video ads;
- Customer support: ElevenLabs voice plus custom-built agents, working around the clock;
- Every heavy asset is outsourced: doctors, prescriptions, and logistics sit with telehealth platforms like CareValidate and OpenLoop, leaving him with only the light-asset middle layer and customer acquisition.
Put plainly, he swapped an entire traditional pharma-ecommerce org chart — design, engineering, marketing, support — for subscription services costing a few dozen dollars a month.
My take: the story isn't really about selling drugs
What's worth chewing on here isn't the fat margins on weight-loss drugs. It's the new organizational form this validates: one person + a shelf of AI subscriptions = output on par with a several-hundred-person company.
Note that Gallagher isn't some technical genius. His edge is execution and judgment: knowing what to sell, who to sell it to, and how to wire the tools together. In other words, AI has floor-priced "execution" — what's now scarce is only "knowing what to do."
Two practical tips if you're eyeing a side project
- Stop agonizing over which AI tool to learn. First find one small business you understand better than most people, then arm it with AI as your free workforce;
- Producing creative assets is now nearly free. A shout-out to the tutorial in the same Rundown issue: Canva's Magic Layers auto-splits any flat image into editable layers — tweak the text, swap the product shot, recolor the background without redoing the design. Anyone making e-commerce images or posters should give it a try.
The era of the one-person company might actually be starting.
