Health insurance technology · ACA marketplace enrollment

HealthSherpa

A Sacramento company that rebuilt the front end of HealthCare.gov for agents and carriers. It was the first private firm approved for the federal Enhanced Direct Enrollment pathway, and it now works inside the biggest fraud crackdown the ACA marketplace has seen.

Two weeks after the crash

HealthCare.gov went live in 2013 and did not work. It was slow, buggy and hard to navigate, and the story of its failure ran for weeks. Two weeks after the launch, three programmers in the Bay Area put up a plain page where a shopper could enter a ZIP code and see plans and prices.

“When HealthCare.gov first launched, the website couldn’t handle the traffic and crashed immediately,” George Kalogeropoulos said later. By November 19, 2013, CNBC was reporting that the Department of Health and Human Services had met with the team. The site was a workaround. What grew out of it is federal enrollment plumbing that thousands of licensed agents now use instead of the government site.

The problem under the problem

The broken website was the visible failure. The durable one is the shape of the market. Most people who buy a subsidized plan do not do it alone. By 2024, according to a 2026 HHS issue brief, agents and brokers facilitated 78 percent of active plan selections, up from 55 percent in 2021. And the buyers are not wealthy: co-founder Ning Liang said in 2020 that the average HealthSherpa household income was around $21,000 a year.

For five years a private site could help someone compare plans but then had to hand them to HealthCare.gov to finish. In the fall of 2018 CMS opened the Enhanced Direct Enrollment pathway, which lets an approved entity host the eligibility application itself. Primary EDE entities integrate with more than 20 federal APIs and must pass a third-party audit plus CMS approval and ongoing monitoring.

Three founders and a spreadsheet

Kalogeropoulos grew up in Greece. “My father was a sculptor and my mother was a tutor, so money was very tight growing up,” he said. The family spent a year in the United States, 1990 to 1991, on Medicaid. He studied political science at Yale, then spent three years at the hedge fund Bridgewater. He and Ning Liang went through Y Combinator in 2012 with a model that predicted rent prices; investors were not interested. When the government began releasing hospital charge data in 2013, the pair built a search tool called OpsCost on top of it. Cat Perez, who had just won a hackathon with a similar project, joined and was named a co-founder and chief product officer in 2015.

First through the door

On December 4, 2018, HealthSherpa announced it was the first company approved to use EDE, calling itself “the first and, thus far, only private marketplace live with EDE.” A year later, per a company post cited by Wikipedia, 10 of the 11 issuers approved for EDE ran on its platform. That leasing model shows in the public record: the CMS list of approved EDE entities dated September 27, 2023 shows BlueCross BlueShield of South Carolina, Kaiser Foundation Health Plan and Sanford Health Plan reaching consumers through healthsherpa.com subdomains.

The business stayed small on paper. In 2019 Kalogeropoulos said it had revenues in the mid seven figures, about 30 full-time staff plus seasonal help, and no plans to raise. The enrollment claims climbed anyway: 1.8 million people since 2014 as of 2019, more than 6 million by October 2021, and today, on the Y Combinator profile, “Over 10 million enrolled since 2014.”

When the channel became the story

In 2024 the speed that made EDE valuable made it a target. CMS reported that from January through August 2024 it received 90,863 complaints that a consumer’s plan had been changed without consent and 183,553 complaints of enrollment without consent, and that it suspended 850 agents and brokers between June and October.

A civil suit filed in the Southern District of Florida on April 12, 2024 alleged a large scheme run out of two Florida call centers. Reading the complaint, the analyst Andrew Sprung noted that the defendants were alleged to own three proprietary EDE web brokers, Benefitalign, Jet Health Solutions and Inshura, and that “Broker switches enacted via proprietary EDE would be invisible to other web brokers” including HealthSherpa, which he described as the dominant one. HealthSherpa was not a defendant, and no public record found for this profile names it as a target of CMS enforcement.

On July 16, 2024 the company announced a shared registry, Member Defense Network, meant to spot duplicate enrollments across carriers, check documented consent, and hold back commissions where consent is missing. Ambetter, Molina and Highmark were among the launch insurers. Agents were split. The attorney James Napoli said the consent check “is one that occurs after the horse has left the barn.” No published result was found showing whether the network met its stated goal of cutting unauthorized switching by 90 percent for participating insurers by January 1, 2025.

The 2026 squeeze

The enhanced premium tax credits expired at the end of 2025. Sign-ups for 2026 fell by more than a million to 23.1 million, and KFF projects effectuated enrollment dropping 21.5 percent to roughly 17.5 million. On August 31, 2026 CMS canceled about 315,000 enrollments covering more than 760,000 people. From 2027, federal open enrollment shortens to six weeks.

What is proven, and what is still claimed

Read plainly: the regulatory standing and the carrier relationships are documented, the scale is not. CMS publishes nothing on how many people each web broker enrolled, so every market share figure traces back to the company. Abuse of the channel is heavily documented, and the enforcement actions and the one large civil complaint point at other operators.

What to watch

• Whether volume holds after the enhanced subsidies lapsed. KFF projects effectuated enrollment down about 21.5 percent in 2026.
• New CMS requirements on the channel: re-identity proofing, Social Security numbers on agent-assisted applications, and electronic consumer authorization.
• Any published result from Member Defense Network.
• A first Form D, or any disclosed financing, after eight years without a priced round on record.
