AI Helped One Man Build A $1.8 Billion Telehealth Startup

When OpenAI CEO Sam Altman predicted in early 2024 that a one-person, billion-dollar company would emerge, most observers assumed it would be a pure AI play. Instead, the closest candidate so far is a telehealth middleman selling compounded weight-loss drugs.

Matthew Gallagher, 41, built Medvi with $20,000, more than a dozen AI tools, and a willingness to treat every business function as a prompt.

Medvi opened for business in September 2024

Medvi generated $401 million in revenue in 2025, its first full calendar year, on 250,000 customers. Net profit came in at 16.2%, or $65 million, according to financials reviewed by the Times.

The company is now on track for $1.8 billion in annual sales in 2026.
