Marketplace Movers: April 2026
The story this month is two-sided. AI scribes and clinical workflow tools are selling. Big-name digital check-in incumbents had a quiet month. And the top three gainers all share one trait, they're free to providers.
Gainers
1. Labcorp Diagnostic Assistant: +18 customers (568 → 586, +3.2%)
Labcorp's Diagnostic Assistant was the biggest absolute gainer of the month. The product surfaces all of a patient's Labcorp results, not just the labs the practice ordered, which makes it a genuinely interesting form of record sharing. Longitudinal lab data in a digital format, delivered inside the EHR workflow without pages of notes to read or summarize. Labcorp has sent results electronically to athena for more than a decade, but they showed up as documents and in athena's native flowsheets. Extending into the workflow layer with their own app is a meaningful change.
It sits in the Clinical Workflow Acceleration category alongside the AI scribes, but the business model makes it hard to compare. The app is free for practices that already send volume to Labcorp, which makes it easier to post big growth numbers than for partners selling a standalone product. It also begs the question whether practices are actually using it.
Bonus: Quest launched what sounds like the same app on the marketplace this month. I'll be watching its growth.
2. Parachute Health: +18 customers (155 → 173, +11.6%)
The DME ordering platform had the largest percentage growth of the top three gainers this month. An orthopedic ops friend once told me he sent patients to Amazon to buy braces because the prices were so much better than DME shops. Parachute is solving the version of that problem with an app that lives inside the EHR, connecting practices to DME suppliers and handling auth and payer requirements without sending the patient elsewhere.
Parachute does one thing, and the growth rate suggests focus is paying off in a category where most competitors bundle DME ordering with inventory management. Especially early in a category's evolution, partners that resist feature creep tend to grow faster than partners that try to absorb every customer request. Parachute looks well-positioned to move into inventory management once they have an established customer base that loves them.
Like Labcorp, Parachute's product is free to providers, so marketplace growth doesn't directly equal business success. The reviews suggest they have many happy customers.
3. Fullscript: +15 customers (662 → 677, +2.3%)
Fullscript already had the largest customer base of the three top gainers heading into April, and they still added 15. Steady growth on a big base. The product lets providers pre-fill carts of supplements for patients and, depending on configuration, earn margin on the purchases.
Fullscript's integration is one of the lowest-friction examples in the marketplace. Practices don't have to change their workflow much to use it, which is part of why the growth keeps compounding on an already-large base.
Like Labcorp and Parachute, the product is free to providers, and depending on configuration it can earn money for them. The reviews are strong.
Honorable mentions worth watching: Suki AI (+14), CarePilot AI Scribe (+14), DeepCura (+11), Heidi (+8). All ambient AI scribes. None individually crack the top three on absolute count, but the category continues to have legs.
Decliners
1. A patient scheduling automation partner: -27 customers (41 → 14, -65.9%)
One partner was an outlier in April's data. The decline happened in a single week and the count has been flat since. Sharp step, then a new floor. The shape of the data points to a single large customer departing or a portfolio change, not gradual churn. I don't have visibility into the cause and don't expect it to ripple into the broader category.
2 - 5. The mid-2010s incumbent cluster: avg -7
Four big-name partners that launched in the 2010s took the next four spots. With athena's core patient check-in offering taking share from above and AI startups taking share from below, the original marketplace incumbents are squeezed from both sides. Classic disruption pattern. I wonder if Jonathan Bush ever considered we'd see it play out inside the marketplace itself. I'll be watching to see whether this is a trend or a feature of April 2026.
If your company shows up in this analysis and the read doesn't match what you're seeing internally, I'd rather hear it than not. Same offer for partners who think they should have shown up and didn't.
I'll be back in early June with May's edition.

Methodology
Net change in total customer connections over the April 2026 calendar month. Snapshots taken 2026-03-31 and 2026-04-30. Partners must have had at least 10 customers at the start of the period to qualify. n=527 partners present in both snapshots; 231 cleared the floor.
