Hundred Health Acquires BellSant to Supercharge AI-Driven Longevity Platform Ahead of Full Launch

Hundred Health, the world’s most accessible and comprehensive longevity platform, today announced an all-stock acquisition of BellSant, a health and longevity platform. The deal gives Hundred Health access to one of the world’s most comprehensive libraries of proprietary longevity studies built by 25+ researchers from Johns Hopkins, Harvard, Columbia, and Stanford across aging, genomics, metabolic biology, sleep, and cognitive decline. Hundred Health plans to integrate this data into its AI engine to improve its health recommendations and insights. Sign up for early access at www.hundred.com.

BellSant’s proprietary datasets, spanning aging, genomics, metabolic biology, sleep science, and cognitive health, provide optimal biomarker ranges, hazard-ratio models, and demographic personalization logic. Integrating these assets will strengthen Hundred’s key features including peer-based comparisons, dynamic reference ranges, and longitudinal health tracking, all delivered through clear, narrative-driven insights rather than raw data dumps.

“Matt and the BellSant team have assembled one of the world’s richest longevity datasets,” said Tyler Smith, Founder & CEO of Hundred Health. “By folding their science directly into our platform, every member will have on-demand access to the collective expertise of dozens of leading researchers to inform smarter, personalized health decisions.”

BellSant founder Matt Fellowes joins Hundred’s advisory board, bringing his vision for evidence-based, consumer-centric healthcare. Select engineering and data talent from BellSant will join Hundred to help merge the two platforms and support Hundred’s roadmap for dynamic health predictions, precision interventions, and next-generation longitudinal coaching.

“Choosing a future for BellSant’s platform wasn’t a decision we made lightly. After careful evaluation, it was clear that Hundred represented not just the right home but the right future,” said Matt Fellowes, Founder of BellSant. “Tyler and his team aren’t just building technology, they’re building a fundamentally better model of healthcare. One that is intelligent, personal, and empowering. I couldn’t imagine a better partner to carry this mission forward.”
