Founder’s Story:

The Why Behind Our Mission

Xavier Serrano is a pioneering entrepreneur in personalized preventative healthcare, with over 20 years of experience transforming how people engage with their health. As the founder of two forward-thinking ventures—Marqi Health and Marqi Medical—he's leading a movement toward a more vibrant, proactive, and data-driven model of care.​

Marqi Health, Xavier's first startup, redefined preventative care by integrating it into large group health plans. Through strategic deals with Fortune 100 companies and longevity-focused partners, he helped broker over $4 million in annual contracts, directly impacting more than 500 lives—detecting 10 early cancers, 110 cases of heart disease, 140 prediabetics, 13 brain aneurysms, and 80 actionable genetic mutations.​

A deeply personal experience led to the launch of Marqi Medical. “2020 changed everything for me. My dad, a healthy man who exercised and saw his doctor regularly, had a massive heart attack that nearly killed him.” After traditional providers missed his father’s heart condition, Xavier realized the urgent need for a system to change. To use the available diagnostic tools, regardless of cost. Marqi Medical was born to bridge that gap—pairing the most advanced diagnostics, AI-driven health insights, and high-touch coaching with a commitment to meaningful, long-term health transformations.

Today, Marqi Medical delivers the most comprehensive and scalable preventative care platform in the market—serving as the infrastructure behind a new generation of concierge doctors across the U.S. Through a seamless portal, Marqi coordinates care, testing, imaging, coaching, and longitudinal health tracking—empowering physicians to focus on medicine, while clients experience tangible, life-changing results.​

With a personal transformation story—having reversed brain fog and fatigue to feel "10 years younger"—Xavier is on a mission to make Marqi synonymous with peak performance and proactive health ownership. His background in insurance gives him a rare advantage: knowing exactly how to align health innovation with payer interests, public systems, and underserved populations.​

Driven by integrity, innovation, and client empowerment, Xavier continues to push the frontier of preventative care—leveraging the latest in AI, genetics, and epigenetics to turn healthcare into a powerful engine for longevity and vitality.​

Marqi Medical is currently part of the USD Brink Accelerator, UCSD Talent Foundry, and SDSI, and guided by a strategic advisory team including Trish Lady, David Favela, and Jerry Swain.​

"We're not just preventing disease—we're building the future of personalized healthcare that helps people live younger, longer."
