Leadership
The founders and executives building Marqi Medical.

Xavier Serrano
Founder & CEO
Xavier founded Marqi Medical after his father survived a widow-maker heart attack. With 20+ years in the group health insurance industry, he saw firsthand how predictive tools fail in practice: scores that don't calibrate, models that don't validate, and claims that don't survive scrutiny. He built Marqi to be different.

Dr. Erica Oberg
Chief Medical Officer
Dr. Oberg brings clinical expertise to ensure Marqi Index predictions are clinically meaningful and actionable. She bridges the gap between data science outputs and care team workflows, ensuring risk scores translate to interventions that improve patient outcomes.
