Matthew Gallagher, a 41-year-old entrepreneur from Los Angeles, launched Medvi, a telehealth provider of GLP-1 weight-loss drugs, using $20,000 and various AI tools to streamline operations. In its first month, Medvi attracted 300 customers, and by its second month, that number grew to 1,000. In its first full year, the startup generated $401 million in sales, and it is on track to reach $1.8 billion in 2025 with only Gallagher and his brother Elliot as employees. Gallagher utilized AI for coding, website copy, customer service, and performance analysis. Despite its rapid growth, Medvi has faced legal challenges, including a warning from the Food and Drug Administration about misleading advertising claims. Gallagher aims to expand Medvi's offerings, including men's health products and meal delivery services, while maintaining a lean operation. He plans to reinvest profits into a foundation supporting homeless youth and animal rescue efforts.
