Practice identity infrastructure

It all starts with Practice Identity.

We tell you whether who you’re selling to is who you should be selling to — and when it isn’t, who is. Practice identity infrastructure for US healthcare, built on ownership resolution: who’s real, who owns it, and which rows on your file are the same buyer — with the evidence attached.

Early access opens in batches. First file washed free when you’re in.

Re-verified quarterly

Illustrative records — parent companies are real, practices are fictional.

  • ~25%of US dental practices are DSO-affiliated
  • ~50%of veterinary clinics are corporate-owned
  • 47%of physicians remain in small practices — down from 61% in 2012
  • 130+PE-backed platform groups actively buying in dental alone

Figures from published industry research, 2024–26 (ADA/HPI, AAHA, AMA). Penetration estimates vary by source and by whether they count clinicians, practices, or locations.

Same file back. Three columns smarter.

Status, ownership, and the rollup key. These six rows are four buyers — two of the flags are the same purchaser.

Illustrative sample. Practice names are fictional; parent groups are real companies. Independent means no parent on record as of the verification date — re-checked quarterly, never sold as a certificate.

How it works

Your file in, your file back — that’s the whole product.

01

Send us your file

A CSV of practice names is enough. No contacts needed.

02

It comes back three columns smarter

Operating or not. Owned by whom, with the evidence attached. Which rows are the same buyer.

03

We keep it true

Re-verified every quarter. You hear the month something changes.

The ownership graph

The layer no database can see.

Solo practices show up in NPI files. Health systems and IDNs show up in the enterprise databases. The layer in between — PE-backed platform groups and mid-size MSOs that own Main Street medicine — shows up in neither, because it leaves no claims trail and no registration trail.

Corporate control in this layer is designed not to appear in the corporate record. It surfaces in what practices actually run: shared booking accounts, common analytics tags, parent careers pages, footer entities. That’s the record we read — and mapping this layer is the whole company.

  • 850,000+US practice locations tracked
  • 29,000+corporate-affiliated locations mapped
  • 100%of verdicts dated, with evidence attached

Monitoring

Then we keep it true.

Five to eight percent of practices change hands every year. On a 5,000-practice file that’s 60–100 changes a quarter — each one an account that just got acquired, closed, moved, or reset its budget.

So your whole file is re-verified every quarter, and each month you get the exceptions — with the evidence attached. Most months the report says nothing changed. That’s it working.
