In September of 2024, Matthew Gallagher, a 41-year-old entrepreneur who has no flashy degree or venture capital network, launched Medvi — a telehealth company that has GLP-1 weight-loss drugs at its center — in his own living room in Los Angeles. He utilizes AI tools such as ChatGPT, Claude, Grok (coding), Midjourney (visuals), and store-specific AI agents (marketing, customer support, scheduling, and operations) to develop the entire operation with just $20,000 and a laptop, and all this takes two months.

He vibe-coded the site and did ads and branding by AI and could even make calls using an AI copy of his voice. It grew quickly to serve 250,000 customers and reported 401 million dollars in revenue in the first year of operation, with a net profit margin of 16.2%, which is nearly triple the larger Wal-RT competitors such as Hims and Hers.

Gallagher introduced his sole full-time employee, his younger brother Elliot. They are dependent on the support of contract engineers and account managers, yet the main business is executed through AI automation. Medvi is estimated to have reached somewhat surprising levels of sales this year (2026).

It is a story featured by The New York Times that meets predictions by technology leaders such as Sam Altman that AI would allow a single individual to build a billion-dollar business. It features the radically reduced barriers to entrepreneurship and how small teams are competing with big companies due to their unbelievable efficiency and innovation through artificial intelligence.

Though there are concerns regarding the long-term regulatory and competitive threats on the telehealth front, the story of Gallagher indicates that in the era of AI, an individual who wills it and has access to intelligent tools can literally do anything that previously needed an entire group of people and a lot of money. It may be the next generation of high-impact startups that are ultra-lean and changing industries.
