The AI Solopreneur: How One Founder Built a $400M Company Almost Alone

What if you could build a company generating hundreds of millions of dollars — with essentially no employees? That's no longer a thought experiment. It's the real story of Matthew Gallagher and Medvi — and it may permanently change how we think about scale, headcount, and the future of startups.

The One-Person Company Generating $401 Million

In September 2024, Gallagher launched Medvi — a GLP-1 telehealth startup focused on weight-loss medications — from his Los Angeles home with $20,000 in capital and over a dozen AI tools. No office. No formal staff (aside from his brother Elliot who joined later).

First-year results:

• •Revenue: $401 million
• •Customers: 250,000
• •Net profit margin: 16.2%
• •2026 projection: $1.8 billion in revenue

For context: Hims and Hers — a major competitor in the same space — generated $2.4 billion in revenue but required 2,442 employees and achieved just a 5.5% profit margin. Medvi operates at nearly triple the margin with two people.

How AI Replaced an Entire Team

Gallagher didn't just "use AI" — he built a complete operating team out of AI tools. Specifically:

• •ChatGPT, Claude, Grok — writing code, generating marketing copy, building the website
• •Midjourney & Runway — producing ad visuals and video creative
