Thesis
We’re all patients in a broken healthcare system. AI creates a once-in-a-lifetime opportunity to redefine how care is delivered. The implications are massive — better health for millions, lower costs for families, and a happier society.
About
Sam partners with founders obsessed with transforming the broken healthcare system from the ground up. The former entrepreneur and operator has a non-traditional path into investing, having started an e-commerce brand and a surf school before shifting into the world of healthcare at Nomad Health. He's most energized by close collaboration with founders—ideating on strategy, diving into challenging problems, and discovering solutions through creative thinking together.
