Brief

Turner Novak’s post summarizes a Peel Pod interview with Al from NexHealth that explains why so many dental and medical offices remain on legacy, on-prem systems: practices digitized in the 1990s–2000s, use local SQL databases containing live patient/billing records, and avoid high-risk migrations. Incumbent EHR vendors often lack enterprise features (logging, SSO) and are structurally incentivized to restrict data portability, creating vendor lock-in that blocks third‑party innovation. Novak highlights NexHealth’s trajectory — now serving 89 million patients and hosting the stack for ~81% of new AI healthcare startups — and recounts founder-level survival details (once $4k in the bank, a $36k pre-pay that saved the company). The conversation concludes that AI’s economic value in healthcare will accrue to chips, models, and the action layer rather than legacy incumbents.

Why it matters

75% of dental offices still run on on-prem servers (a desktop/server in the office), often using legacy SQL databases installed in the 1990s–2000s — migration is avoided because patient records, billing data, and compliance make any data loss or incompatibility high risk.

Key details

  • Incumbent EHR/vendors routinely hinder modernization: they often lack standard tooling (logging, SSO), make data access and migration dependent on vendor cooperation, and are economically incentivized to keep practices inside their ecosystem, producing strong vendor lock-in and downstream innovation friction.
  • NexHealth now serves 89 million patients and claims 81% of new AI healthcare startups are built on its infrastructure; founder Al told Turner Novak the company once had $4,000 in the bank, a maxed AmEx, and survived thanks to a pivotal $36,000 pre-pay.
  • Novak/Al argue healthcare skipped several platform shifts and that AI value will concentrate in chips, models, and the 'action layer'; supporting metrics cited include a 72% sales win rate, a $391k early raise from professors/customers, and a later $176M round the company says it didn't need.

75% of dental offices still run on servers in the closet

"Go to your local dentist and there’s a high chance they actually have a server somewhere in the office. A desktop computer, using a server-client setup, with an IT team managing it.

A lot of these offices digitized in the early 2000s or the ‘90s. At the time, those were the options available to them. Modernizing that software doesn’t generally happen, for two reasons.

One is change management. Migrating your system of record is really high risk.

Second, most of these incumbent providers actually make it hard for you to migrate in the first place.

If you’re migrating, you have this SQL database in the office that you own and manage. You’re not a tech company. And then it’s managed by a third party. And all these records are stored in a certain format.

So let’s say you’re going from software A to software B. The migration and the format of that data matters. And it's patient data. You have your billing data. There's a lot of compliance needs behind it. And of course, you’re still serving patients and their records.

So any loss of that data, or it not being compatible with the next system you’re going with, is incredibly risky. Most offices would rather not even take that risk.

A lot of things we expect in tech just don't exist in healthcare. For example, take Salesforce as our system of record. We expect Salesforce to provide us logging data, SSO, and so on.

In our space, at least historically, the vendors just don’t provide those tools. Either because of self-interest, or just a bad product.

As a result, over time the providers themselves are stuck on older systems. And they're unable to upgrade.

And even when they try, they have to go through a ton of friction to do it. Mostly because the incumbents are very incentivized to keep you within their existing ecosystem, unless they’re now selling you a cloud version themselves.

And generally speaking, the business model of most electronic health record systems is really oriented around making sure that migration of data, change management, or access to the office’s data needs permission from the vendor themselves. For any office or any third party to be able to innovate or adopt any tools.

This has a massive downstream impact on the rest of the industry."

New @ThePeelPod with @alfromnexhealth

Today @nexhealthHQ infrastructure serves 89 million patients and 81% of new AI healthcare startups are built on it.

But at one point, the company had $4k in the bank, a maxed-out Amex card, and was on the brink of running out of cash.

I sat down with Al to talk about why 75% of dentists still run a server in their closet, the reason innovation is so hard in healthcare, and why AI value will accrue to chips, models, and the action layer.
