$100M ARR. 30 people. Two and a half years.
Cobi Blumenfeld-Gantz built Chapter, an AI-powered Medicare navigation platform, after watching his parents struggle with the enrollment process. His mother ended up with lifetime late-enrollment penalties after being told to sign up too late — a government-imposed consequence that Blumenfeld-Gantz argues is emblematic of an industry that routinely fails consumers.
The core problem is structural. Most Medicare brokerages are financially incentivized to push plans with higher broker commissions rather than the best fit for the enrollee. The rest of the market is fragmented between local mom-and-pop brokers and legacy call centers that function primarily as marketing operations. No one, in his telling, had built technology that genuinely prioritized the consumer.
“We went one to a hundred mil in run rate revenue in about two and a half years... I don't think of ourselves as a health care company, really. I think of ourselves as a really good tech company, so we compare ourselves to the fastest growing companies — we grow as fast or faster than companies like Ramp, companies like Glean... All of our corporate headcount — product, engineering, growth, legal — we're about 30 people.”
How it works
Chapter operates through enterprise partners — financial advisors, health systems, hospitals — rather than direct-to-consumer marketing. A prospective enrollee contacts Chapter, provides basic information, and is connected to a full-time licensed Medicare advisor employed by the company. The advisor handles the actual guidance, but every interaction is backed by software that does the heavy lifting: automating form submissions across dozens of insurance carrier portals (most of which have no APIs), cross-referencing physician networks, and pulling prescription drug pricing across Medicare plans and pharmacies. That last query alone, Blumenfeld-Gantz says, draws on tens of billions of records.
The model keeps headcount low by design. The entire enterprise growth team is six or seven people. Corporate headcount across product, engineering, growth, and legal sits at around 30.
Scale and fundraise
Chapter went from $1M to $100M ARR in roughly two and a half years. Blumenfeld-Gantz benchmarks that against Ramp and Glean rather than other healthcare companies, arguing the bar in healthcare is too low to be a useful reference point.
The company has raised approximately $100M in a Series E led by Al Gore's Generation Investment Management.
At 30 people and $100M ARR, Chapter is generating roughly $3.3M in revenue per employee — a ratio that would be notable in any sector, and is extraordinary in healthcare services.
