Sam Altman said 1-person billion-dollar companies were coming
Medvi just proved him right
Matthew Gallagher started Medvi in Sept 2024 $20K. No team. No employees.
By end of 2025:
→ $401M revenue
→ 250,000 customers
→ 16.2% net profit margin
Hims & Hers runs the same market
With 2,442 employees
At 1/3rd the margin
How did 2 people beat 2,442?
Simple. Gallagher didn't hire. He stacked AI.
→ ChatGPT, Claude, Grok → built the platform
→ Midjourney, Runway → ran all ads
→ ElevenLabs → handled customer comms
→ Partners → medical compliance
He owned the customer AI ran everything else
Feb 2026: launched men's health line 50,000 signups in month 1
Still 2 employees
Here's the real lesson
Most businesses bolt AI on at the end Gallagher built AI-first from day 1
That's the difference between AI as a tool And AI as the company
The billion-dollar solo founder era isn't coming
It's already here
