About us

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 realised 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.
