Matthew Gallagher did not set out to build a billion-dollar startup in the usual Silicon Valley way. He launched Medvi AI in September 2024 with $20,000 and a set of AI tools. He did so without raising external funding or building a large team. Operating from his home in Los Angeles, he focused on the GLP-1 telehealth market and scaled the business quickly. This is what makes this story stand out. Within a year, the company’s growth began to draw wider attention.

Medvi Has 2 Employees and Nearly Triple the Net Margin of Hims and Hers

Medvi AI is a GLP-1 telehealth company that sells weight-loss drugs online. It does not run its own medical network. Instead, it connects customers to doctors through platforms like CareValidate and OpenLoop Health.
Medvi’s first full year gives a clear picture of how the model works. The company generated $401 million in revenue in 2025, with a 16.2% net margin and about $65 million in profit, according to reports. It also reached roughly 250,000 customers during that period and is now on track to hit $1.8 billion in 2026.
The team behind this scale is relatively small. Gallagher runs the business with his brother Elliot. He is the only full-time employee, supported by contractors and external platforms.
For context, Hims & Hers Health reported $2.4 billion in revenue last year. This is with a 5.5% net margin and over 2,400 employees. Medvi’s margins are close to three times higher. This is mainly because it operates with a much smaller team and lower costs. But he also suggested,
“At this point, I kind of want to hire people because I’m lonely.”

Most of Medvi’s operations are handled through existing AI tools. Gallagher used ChatGPT, Claude, and Grok for building and running internal systems. Marketing content was generated using Midjourney and Runway. Meanwhile, customer communication relied on ElevenLabs. Gallagher said,
“It’s not an A.I. company, but I did it with A.I.”
In addition, back in 2024, Sam Altman said AI could soon make it possible for a single person to build a billion-dollar company. At the time, it was seen as a long-term shift and not something immediate. Medvi has come close to that idea in practice. Altman later said the company appeared to validate that view and added that he would like to meet Gallagher.

Instead of building medical infrastructure, Medvi plugged into platforms like CareValidate and OpenLoop Health. They handle doctors, prescriptions, and compliance. This setup lets the firm focus mostly on marketing and customer acquisition.

Questions Around Sustainability & Regulation Rise
There are limits to how durable this model is. The FDA has issued warning letters to companies offering compounded GLP-1 drugs. This could affect operators in the space. The business also does not rely on proprietary technology. This makes it easier for others to replicate using similar tools and partnerships.
Despite this, the company shows how far a small team can go using existing AI tools and partnerships. Whether this model holds over the long term is still uncertain, but it has changed expectations around how efficiently a company can be built.
