MEDVi used AI tools to replace nearly every business function that a company of its size would normally staff humans to perform — including writing all software code, designing the website, generating marketing content, running analytics, and handling customer communications. This allowed two people to launch and operate a company that reported $401 million in 2025 revenue.

Founder Matthew Gallagher built MEDVi from scratch in two months with $20,000 using more than a dozen AI tools. He used large language models (ChatGPT, Claude, Grok) to write code and copy, MidJourney and Runway for images and video, ElevenLabs for AI voice tools, and custom AI agents to connect software systems and generate real-time business analytics. All clinical operations were outsourced to third-party partners CareValidate and OpenLoop Health, meaning no clinical or customer-facing roles were filled by MEDVi employees. OpenAI CEO Sam Altman cited MEDVi as evidence of his prediction that AI would enable a one-person billion-dollar company. Research firm Forrester published a rebuttal calling that framing misleading, and arguing that what MEDVi demonstrated was primarily the ability to use AI tools to scale deceptive marketing rather than to replace legitimate business operations.
