HealthSherpa: the quiet front door to affordable care.

It is the first week of November, and somewhere a 41-year-old freelance designer is staring at a screen, trying to figure out whether she can afford to get sick next year. She types her zip code, her income, her birthday. Seven minutes later she has a plan, a price, and a subsidy she did not know existed. She never saw the brand name. That is the point. The site she used was HealthSherpa, and this scene plays out millions of times each winter.

Today HealthSherpa is the largest private channel for Affordable Care Act enrollment in the United States. It handled coverage for more than five million people in plan year 2023 and accounts for roughly 35% of all enrollments through the federally facilitated marketplace. It is, in the plainest sense, infrastructure - the plumbing behind a law that millions depend on. And almost nobody knows its name. The company seems fine with that.

A law that worked, and a website that didn't.

In October 2013, HealthCare.gov went live to enormous fanfare and immediately fell over. It was slow. It crashed. People who wanted coverage - people the Affordable Care Act was written for - could not get through the front door. The subsidies were real. The plans were real. The experience of finding them was a small disaster.

Here is the irony nobody enjoyed at the time: the hard part of the ACA was never the insurance. It was the interface. A generous benefit is worthless if the person it is meant for gives up at the loading screen. The gap between policy and people was, of all things, a user-experience problem.

Three programmers, two weeks, one working site.

George Kalogeropoulos and Ning Liang had met through Y Combinator. Kalogeropoulos had built companies before - OpsCost, RentMetrics - and had done a stint on portfolio construction at Bridgewater Associates. Watching the government site stumble, they did the thing engineers do when a system is broken and the spec is public: they built their own.

Two weeks after HealthCare.gov launched, HealthSherpa.com went up - a clean alternative that let shoppers see plans and prices quickly. It was not meant to be a company. It was meant to work. Cat Perez joined in 2015 as co-founder and chief product officer, and the side project hardened into a business. The bet was simple and slightly heretical: that a small team could out-execute a federal contract on the one thing that mattered, the experience of enrolling.

Pictured (in spirit): the kind of founders who read a 900-page law as a product brief and a broken launch as a market opening.

One platform, three very different doorways.

HealthSherpa does not really sell insurance. It sells the absence of friction. The same underlying engine serves three audiences who would never sit at the same table: a consumer who wants a plan tonight, an agent juggling hundreds of clients, and a carrier that needs federally compliant enrollment rails.

The elegant, slightly sneaky business model

Consumers pay nothing. Agents pay nothing. So who keeps the lights on? Carriers do, through the Enhanced Direct Enrollment platform and enrollment technology fees. The arrangement quietly aligns everyone: HealthSherpa makes money when people complete enrollments, not when someone gets steered into a pricier plan. The incentive to upsell, the original sin of insurance shopping, mostly disappears.

The numbers do the arguing.

It is easy to claim you have fixed enrollment. It is harder to grow 50% in a year while the marketplace you sit inside grows 13%. HealthSherpa did exactly that - pulling away from the field rather than drifting with it.

There is more proof in the receipts. One month into a recent open enrollment, HealthSherpa reported signing up 2.7 million people at a median net premium of $5.61 a month - a reminder that the subsidies were always there, waiting for someone to surface them. In 2018 it became the first company approved for the government's Enhanced Direct Enrollment program. By 2019, ten of the eleven approved insurers were running on its platform. The endorsement that matters most is the boring kind: other serious players built on top of it.

Make coverage findable, and the rest follows.

The company's stated purpose is unglamorous and exactly right: help Americans find, understand, and enroll in affordable health coverage. No moonshots, no manifestos about disrupting medicine. Just the stubborn belief that a benefit you cannot navigate to is not really a benefit. HealthSherpa has raised under $10 million in total funding - a rounding error by healthtech standards - and used it to enroll people by the million. Capital efficiency as a moral position.

The front door, rebuilt.

Health policy will keep changing. Subsidies expand and contract, rules shift, new arrangements like ICHRA reshuffle how people get covered. Through all of it, the bottleneck stays the same: someone, somewhere, has to actually enroll. HealthSherpa has spent more than a decade making that single step take seven minutes instead of an afternoon of despair. That is not a flashy mission. It is a durable one.

Return to that freelance designer in early November. A decade ago she would have hit a frozen government site, guessed wrong about her subsidy, and maybe gone without. This year she typed in her details, saw her real options at a real price, and clicked enroll before her coffee got cold. The law promised her affordable coverage. HealthSherpa built the door she could actually walk through - and then, characteristically, took none of the credit.
