Public records,read carefully.

Sourcebrook builds ownership data for US healthcare from public records: which company owns which practice, how platforms grow, and which practices are still independent. It is run by its founder, Kevin Koshy, from India.

01 / Why

Most consolidation never makes the news.

Practices change owners one at a time, and most of those moves are never announced. The records still show them: every therapist bills Medicare through an organisation, and the organisation names who stands behind it.

  • What we do

    We read the public CMS files, tie each billing organisation to the platform that owns it where a public source shows the tie, and count its clinicians quarter by quarter. A tie counts from the day its source was public, so history reads as it was known at the time.

  • Who it is for

    Private equity, operators and advisers who need to see a market clearly before they act: who holds each state and metro, which platforms are growing, and which practices have no tie found.

  • What it is not

    Counts of public records, not head counts, ratings or forecasts. No clinician is named. Not investment advice.

02 / How we work

Every claim can be checked.

  • Public records only

    Medicare enrollment (PECOS), the NPI registry (NPPES) and Care Compare, published by CMS, plus the platforms' own clinic lists, press releases and SEC filings for the ties.

  • Tests published, failures included

    Our counts followed the reported numbers of 3 of 5 listed chains; the ones that failed, and why, are on the proof page. Each state's own checks are on the coverage page.

  • Every number recounted

    A second program recounts every published number before release (349 of 349 matched).
