A Single Founder Used AI Tools to Build and Scale a Massive Business

A Los Angeles entrepreneur has built a company on track for $1.8 billion in annual revenue—with essentially just himself and his brother—highlighting a radical shift in how businesses can be built in the age of AI. Matthew Gallagher launched his telehealth startup Medvi using a suite of AI tools to handle everything from coding and marketing to customer service and analytics, reaching massive scale in record time.

Gallagher, as noted in an article in the nytimes.com, spent just $20,000 and two months building the company, using tools like ChatGPT, Claude, Midjourney and Runway to automate core business functions. The results were staggering: 300 customers in the first month, 1,000 more in the second, and $401 million in revenue within the first year—all without a traditional workforce.

This model reflects a broader trend predicted by AI leaders: the rise of “one-person billion-dollar companies.” By replacing large teams with AI agents and outsourced infrastructure, entrepreneurs can move faster, operate more efficiently, and achieve profitability at levels traditional companies struggle to match. Medvi, for example, posted profit margins far higher than much larger competitors.

But the approach comes with trade-offs. Gallagher handles an overwhelming workload, sometimes fielding customer calls himself, and admits the experience can be isolating. While AI enables unprecedented efficiency, it also strips away the human elements of business—collaboration, shared decision-making, and workplace culture—raising questions about what the future of work will feel like, not just how productive it will be.
