Fountain Life Raises $18M to Expand Cutting-Edge Longevity Centers
Eight years ago, orthopedic surgeon Dr. William Kapp attended a medical conference that would change the course of his career. Transitioning from private practice to co-founding and later selling a company focused on critical care hospitals, Kapp developed a keen interest in both the medical and business aspects of healthcare, he told TechCrunch.
At the annual conference hosted by renowned physician-scientist Dr. Daniel Kraft, Kapp was exposed to emerging technologies that could improve patient outcomes while lowering costs. That year, Dr. Peter Diamandis, founder of the XPRIZE Foundation, shared the stage with stem-cell pioneer Dr. Bob Hariri, co-founder of genomics company Human Longevity. Their discussion of genomics, microbiomics, and other advanced health technologies inspired Kapp to take action.
From Longevity Performance Center to Fountain Life
Returning to his hometown of Naples, Florida, Kapp launched the Longevity Performance Center, aiming to focus on early detection and optimization of health.
By March 2020, Diamandis and self-help icon Tony Robbins had learned of Kapp’s center and visited. With their stem-cell startup Fountain Therapeutics, discussions quickly evolved into a merger. By October that year, the collaboration officially became Fountain Life, with Kapp as CEO and Diamandis and Robbins as co-founders and board members.
The current board also features Dr. Bob Hariri as an adviser, Todd Wanek, CEO of Ashley Furniture Industries, and Indian business magnate B.K. Modi as investors.
Series B Funding and Growth
Fountain Life recently secured an $18 million Series B, led by EOS Ventures, with participation from most existing board members. Kapp confirmed that the company previously raised $80 million in Series A funding, totaling about $108 million raised to date.
“Longevity as a serious field of medical study is still emerging,” Kapp explained. When he launched his center, “we didn’t know exactly what longevity meant.” Over the past five years, research has dramatically expanded.
The Three Principles of Longevity at Fountain Life
Kapp describes Fountain Life’s approach as built on three core principles:
-
Prevention: Avoid “dying of anything stupid.” Fountain Life’s centers—currently four, with more planned—focus on early screening for illnesses and chronic conditions, often before symptoms appear. Tests include blood work and body scans assessing over 100 biomarkers, such as liver fat and microbiome concentrations.
-
Optimization: Using scientifically validated treatments to improve these markers.
-
Regenerative Therapies: Employing the latest therapies under FDA trials to treat illness or optimize health.
Screenings may, for example, detect small intestinal bacterial overgrowth (SIBO), which, if untreated, can increase cancer risk. Early detection allows correction of microbiome imbalances through targeted microbiotics.
Technology and Patient Experience
Members undergo tests roughly every quarter, tracking results and consulting through Zori, an AI-powered app.
The service comes at a premium: full annual membership costs $21,500, including comprehensive testing and physician access, while a $10,500 package covers testing and AI tools only, excluding ongoing medical support.
Kapp recalls two compelling cases underscoring the value of early detection:
-
A Robbins fan whose asymptomatic kidney cancer was identified early through testing and successfully treated.
-
Global hotelier Sam Nazarian, exploring Fountain partnerships, discovered a brain aneurysm during testing and underwent successful treatment.
Expansion Plans
Fountain Life is using the new funding to grow its presence. Existing centers operate in Naples, Orlando, Dallas, and Westchester, New York, with Houston set to open in December and locations in Los Angeles and Miami planned for Q2 2026.
Kapp also aims to make longevity care more affordable by training other medical facilities in Fountain Life’s methodologies, expecting broader adoption to reduce costs over time.
Competitive Landscape
Fountain Life is not alone in the longevity space. Dr. Mark Hyman’s Function Health offers roughly 160 blood tests with follow-ups every three to six months for $500/year (with additional costs for extra tests). Function now also provides optional body scans through its acquisition of Ezra, starting at $499.
Fountain Life’s growth and innovative model reflect a rapidly evolving field where health optimization meets cutting-edge technology, appealing to both medical enthusiasts and high-net-worth individuals seeking proactive health management.
