Who Owns Chapter?

Chapter was founded in 2020 in New York by Cobi Blumenfeld-Gantz, Corey Metzman, and Vivek Ramaswamy. Blumenfeld-Gantz spent five years at Palantir before founding the company, and Metzman was a Palantir colleague. The founding premise treated Medicare plan selection as a data problem: seniors choosing among thousands of Medicare Advantage, Medigap, and Part D plans faced a broker industry where advisors earned more for steering customers toward certain plans.

The company built a recommendation engine and advisory model positioned around unbiased plan comparison. Chapter's licensed advisors compare every plan in the market rather than only those paying the highest commissions, a direct structural contrast with the incumbent brokerage model.

Early funding attracted an unusual political mix: Peter Thiel backed the Series A in September 2021, and JD Vance's Narya Capital was an early investor. The company raised $42 million in a January 2022 Series B and $50 million in a May 2024 Series C led by XYZ Venture Capital, reaching $111 million total.

Revenue scaled rapidly through the mid-2020s as Medicare Advantage enrollment surged nationally. A May 2025 Series D brought in $75 million, and by early 2026 the company reported surpassing $100 million in annual recurring revenue, tripling revenue in 2025 while holding corporate headcount flat, a productivity gain attributed to its data and AI-driven platform.

In April 2026, Chapter closed a $100 million Series E led by Generation Investment Management at a $3 billion valuation, more than doubling its worth in under 12 months and bringing total funding to approximately $284 million. The round made it arguably the most valuable private company in senior health navigation. As of October 2026, the company operates from 19 Union Square West in New York and employs approximately 270 people.
