Founded in 2022 by former medical student Woonyeon Kim, GravityLabs develops Moneywalk, a gamification-based healthcare app that rewards and motivates users to increase daily activity through personalized, AI-driven challenges. The service has grown 10× in two years and now counts roughly 1.3 million monthly active users and more than 5 million cumulative users across Korea, the United States, and Japan. Moneywalk’s rapid user adoption has translated into an annual recurring revenue run-rate approaching $25 million, achieved with a lean team of just 20 employees. GravityLabs’ competitive edge lies in its proprietary “behavior change technology” that analyzes activity patterns, sleep rhythms, and reward responses to deliver customized missions and feedback. With fresh capital, the company plans to establish a U.S. office, relocate key staff, and hire local talent while continuing to develop AI-based healthcare products tailored to North America. It also aims to expand through partnerships with insurers, healthcare providers, and wellness platforms, ultimately building an AI healthcare infrastructure for preventive medicine and chronic disease management.
