Which athenahealth Marketplace Vendors Are Growing in 2026

The one number in this category you can verify yourself

Every vendor selling into athenaOne practices publishes logos, interaction counts and funding announcements. Almost none publish growth, because growth is the number that cannot be reframed.

athenahealth solves this for you. Every Marketplace listing carries a practice-connection count, how many practices are actually connected to that product, published by athenahealth rather than by the vendor. Take two dated readings and you have a measured growth rate for the entire category, including us.

That is what this page is. The window is 22 May to 4 September 2026, 105 days.

Method

This uses 22 May 2026 and 4 September 2026 snapshots of the athenahealth Marketplace. The aggregate includes the 532 listings that could be matched at both dates. The ranked cohort is the 241 listings with at least 10 practice connections at the start of the window; low-baseline listings such as Weave are excluded from the ranking for that reason. Both the start and end values are shown for every displayed calculation. Marketplace listings are the cited inputs. Flat and declining listings are excluded from the display table; the aggregate uses all 532 matched listings.

The market baseline first, because it is the part that matters

Across the 532 listings that could be matched at both dates, total practice connections went from 25,802 to 27,184, up 5.4%. 223 listings grew, 256 added nothing, and 53 declined. Any growth number in this category should be read against that aggregate, not against zero.

A connection is not a customer, revenue, or retention record, and a declining connection count is not evidence that a named customer churned.

The leaderboard

241 listings began the window with at least 10 practice connections. Below are the growing listings an athenaOne practice is likely to be evaluating, plus the fastest movers anywhere on the board, ranked by percentage growth. Flat and declining listings are excluded from this display; the aggregate above uses all 532 matched listings.

Two notes on scope rather than percentages.

Weave is excluded from this display. Its reported change, 4 connections to 94, started below the cohort’s baseline threshold of 10 connections at the start of the window, so no growth rate is quoted for it. Exclusion does not make the result irrelevant; it reflects how the cohort was defined.

Our own number, with its base stated: 17 to 40. A percentage off a base of seventeen is a real measurement and a small one. It is the highest growth rate in the cohort and it is also twenty-three practices. Both are true, and a page that printed one without the other would deserve the skepticism it got.

What is growing tells you what practices are actually buying

Read the leaderboard by what the products do rather than by who is on it, and a pattern shows up that the front-desk framing hides.

Two of the seven fastest-growing listings on the marketplace never touch a ringing phone. Automated Prior Authorization by Develop Health went from 42 connections to 63, +50.0%, third-fastest of the 241 listings with a base of ten or more. Arintra, autonomous medical coding, went 21 to 30, +42.9%. The matched population also includes Keragon, which added 29 connections on workflow automation (119 to 148, +24.4%), Direct Care Billing by Hint Health, which added 15 (115 to 130, +13.0%), and Adonis, which added 3 on revenue-cycle work (23 to 26, +13.0%).

The reading we take from it: the demand converting on this marketplace in this window includes administrative automation broadly, prior auth, coding, billing, records, the work that happens after the patient is booked, not the phone alone. A practice buying only a phone product is buying the thinnest slice of the problem, and buying prior auth, billing and the front desk separately means three vendors, three integrations and three seams for the work to fall through.

That is the case for doing the whole path in one integration, and it is why we scope custom athenaOne workflows rather than shipping a fixed feature list. It is also worth saying plainly: Develop Health and Arintra are growing because they are good at a real problem. The point is not that they are wrong. It is that the fastest-moving demand on this marketplace is in the back office, and the number of vendors who can reach it through a single athenaOne integration is small.

What our own snapshot shows

Our listing moved from 17 practice connections and 12 ratings on 22 May to 40 connections and 17 ratings on 4 September 2026, every rating five stars.

What we are not claiming

• Not a smooth curve. The last month ran ahead of the window average, 29 connections on 3 August to 40 on 4 September, +11 in 32 days, against 0.22 connections a day across the full 105 days. We are not calling that a trend. On a base of forty a single multi-location group swings the number, so a one-month rate is noise in both directions. The 105-day figure is the one we publish.
• Not a customer count. Connections measure athenaOne presence, not company size. Phreesia holds 1,182 connections while reporting 4,744 total clients for the quarter ended 31 July 2026, roughly a quarter of its book.
• Not the whole marketplace. 532 of 572 listings could be matched at both dates. Listings created mid-window, including Interactly, have no comparable start value.

How to use this when you evaluate vendors

1. Open the listing. athenahealth publishes the connection count and rating. Compare dated snapshots, because the counts move over time.
2. Ask for the trend, not the total. A large connection count earned in 2020 and a growing one earned this year are different products. Ask when the listing was last updated and when the last review was written.
3. Ask what the integration completes. What specific objects change in athenaOne when the work succeeds, and what happens when it cannot finish.
4. Separate company traction from athenaOne traction. Enterprise health-system traction and athenaOne practice traction are different things, and a practice evaluating vendors should measure the one it is buying.
