Beyond Academia: Dr. David Lim on Building Healthcare Startups

Startup Physicians

What happens when an infectious disease specialist decides to step off the academic path and jump headfirst into the startup world? In this episode, I sit down with Dr. David Lim, a physician-scientist turned healthcare entrepreneur, who shares his inspiring journey from UCSF to the boardrooms of Boston Consulting Group, and ultimately, into founding and scaling impactful healthcare startups. His story is proof that physicians can thrive outside the traditional clinical box—and that our unique training gives us a powerful edge in the business of healthcare.

We explore how David made the leap into consulting, the mindset shifts that helped him succeed in business, and how his medical background gave him a clear advantage when building solutions for real-world healthcare problems. From launching a nonprofit with Michael Porter to co-founding mental health startup Quartet, and now building a virtual-first MSK triage company, David shares invaluable insights about creativity, leadership, and staying mission-focused.

My guest today is Dr. Dave Lim, who has taken many different paths to becoming a startup physician executive. He joined Castlight Health, one of the first cost and quality transparency platforms to enter the market and IPO in 2012. He then joined the Founding Team as employee #1 at Quartet, one of the mental health forerunners expanding access and providing care navigation and support. Today, he is Chief Physician Executive (and also employee #1) at RightMove, a tech-enabled services company providing musculoskeletal care that was spun out of the Hospital for Special Surgery (HSS) - the #1 global, orthopedic institute as ranked by US World & News Report.
