The Billion-Dollar Solo Startup: How One Man Built Medvi — $401M in Year One, $1.8B Run Rate in Year Two — With Just AI and His Brother
In September 2024, Matthew Gallagher did something that most founders would call impossible.
He was 41, living in Los Angeles, with a background that included growing up in a trailer park and dropping out of university. He had no team, no venture capital, and no fancy office. What he did have was $20,000, a laptop, and a relentless belief that AI could replace almost everything.
The results have been nothing short of explosive:
- 2025 (first full year): $401 million in revenue, 250,000 customers, 16.2% net profit margin.
- 2026: On track for $1.8 billion in annual sales.
- Team size: Exactly two people — Matthew and his younger brother, Elliot.
No massive engineering team. No marketing department. No customer-support call center.
Just one founder who treated every part of the business as something he could prompt an AI to handle.
How He Actually Built It
He didn’t hire designers or copywriters. He generated the entire website, ad creatives, videos, and marketing materials with **Midjourney and Runway**.
Customer support? Handled entirely by AI agents that answer questions, process refills, and manage inquiries 24/7.
He even built custom AI systems to analyze business performance in real time.
Everything else he couldn’t do himself — legal paperwork, pharmacy partnerships, doctor licensing — he outsourced to specialists, keeping the core operation lean.
“It’s not an AI company,” Gallagher told The New York Times. “But I did it with AI.”
He started with 300 customers in the first month. Growth snowballed from there. By the end of 2025, Medvi was generating roughly $3 million a day with almost no overhead.
For comparison, traditional telehealth giants like Hims & Hers needed thousands of employees and much lower margins to reach similar scale.
The First Real Proof of Sam Altman’s Prediction
Most people treated it as futuristic hype.
Matthew Gallagher just proved it’s already here.
Medvi isn’t some flashy AI wrapper or SaaS tool. It’s a real, regulated telehealth business moving real drugs to real patients — and it was built and scaled almost entirely by one founder and his brother using consumer AI tools that anyone can access today.
No $100M funding round. No 200-person team. No years of product-market fit experiments.
Just one person, a laptop, and the willingness to let AI do 95% of the work.

What This Actually Means
The old playbook — raise money, hire a big team, spend years building — is being replaced by something far more powerful: one determined founder who knows how to prompt, iterate, and ship at lightspeed.
Gallagher didn’t invent a new drug or a breakthrough algorithm. He simply used today’s AI to remove every traditional bottleneck in starting and scaling a business.
And he’s not alone. More founders are quietly doing the same thing in other verticals. But Medvi stands out as the clearest, most undeniable case yet.
The era of the billion-dollar solo (or duo) company isn’t coming.
It’s already here — and it started with a guy in a trailer park who decided to bet everything on AI.
If you’ve been waiting for proof that one person with a laptop and the right tools can now build something massive…
This is it.
