What Diatonic Healthcare buys

Diatonic Healthcare is a small Miami-based investor and business builder that also lists Baltimore and Dallas as bases. It shows no committed fund and publishes no size range. It works on three healthcare themes: protecting data and systems, access to and pricing of care and drugs, and compliance, supply chain and reimbursement. Its partners have started and sold companies themselves, and it also builds new technology businesses from scratch. It will go outside healthcare now and then, with generalist deals run through a subsidiary, Rivercrest Capital.

Its portfolio page puts every company under one heading that covers both partnerships and companies its team owns, so the size of each stake is not clear. The list includes IT staffing firm Quantix, bought in May 2025, plus Spendrule, Smash, Nymbl and Sunstone. Diatonic also leads acquisitions and capital raising for Nexus IT, a Salt Lake City managed IT provider that has closed five add-ons since June 2025. A small IT or security firm serving regulated clients is most likely to meet Diatonic through Nexus.

Greymont’s take

How Diatonic Healthcare fits a seller

Diatonic suits founders of healthcare technology, compliance or regulated IT businesses who want operators at the table more than a large fund behind them. Each partner has built and sold a company, and two of them run Spendrule day to day. Quantix's founders sold through a broker and said the deal was about trust and legacy as well as the numbers.

Because no committed fund is shown, ask early where the equity comes from, how much of the price is paid in cash at closing, and who holds the debt. Nexus IT's buying is paid for with a $60 million facility from Metropolitan Partners Group, where Diatonic's CEO is also an operating partner. An owner selling to Nexus should also ask who really controls the company, because Nexus's own site names its founder as owner and chairman.

Questions owners ask

Does Diatonic Healthcare only invest in healthcare?

Mostly, but not only. It names three healthcare themes and says it will sometimes invest outside healthcare in markets that improve American lives. Sunstone, a manufactured home park brokerage, is one example, and generalist deals run through its subsidiary, Rivercrest Capital.

Is Diatonic a buyer of IT companies?

Yes, in two ways. It bought IT staffing firm Quantix in May 2025, and it leads all acquisitions for Nexus IT, a managed IT and security provider that reached its 12th deal in August 2026. Nexus says it wants providers serving regulated industries, especially healthcare.

What size company does Diatonic look for?

It does not publish a revenue, EBITDA or check size range, and it shows no committed fund. Its record is the best guide: Quantix came through a business broker, and the Nexus IT add-ons are local IT firms in cities such as Reno, Phoenix and Austin.
