Capabilities

Tools 3

find_businesses

List dentists, eye care practices, vets, dermatology or GI practices in a ZIP code, city or state, optionally filtered by ownership label. With industry "brand", list consumer brands instead (no location needed), filtered by label and by words in the brand, owner, backer or category (name), e.g. pet food brands with no known PE ties. Covers requests like "dentists in Plano, TX with no PE ties" (label=no_known_pe_ties) or "PE-backed eye doctors in 75024" (label=pe_backed,lender_owned). Labels: pe_backed, lender_owned (PE-backed, now lender-controlled), corporate_owned (not PE, owned by a company), health_system_owned, group_practice (owned by its dentists/doctors, no outside investor), vc_backed, no_known_pe_ties, unconfirmed, not_labeled; aliases pe and no_pe. Returns counts by label for the area, total, a page of results (limit up to 100, then next_offset) with each one's label wording and source, and the coverage note. Dental and eye care cover every NPI-registered practice; vet, derm and GI list only the tracked groups' locations. Some listings come from clinicians' individual NPI records and aren't confirmed open.

Discovered
get_group

Get an owner group's ownership details: label and consumer wording, owner or PE backers and since when, PE stake (majority or minority), how it holds practices (buyout, partnership, joint venture, de novo), parent and brands, every source with its headline and date, and known locations by state. Covers questions like "who owns Heartland Dental?" or "is Aspen Dental private equity?" (brand names work). Also answers for consumer brands ("Orvis") and for the companies and PE firms behind them ("Authentic Brands Group", "Sycamore Partners"): the brands on our list they own or back.

Discovered
lookup_business

Checks whether one specific dentist, eye doctor, vet, dermatology or GI practice is private-equity backed, from its name plus city and state or ZIP. A street address or phone number makes the match surer. Also answers for a consumer brand by name or website (e.g. "Orvis" or "orvis.com"), with its owner, backers and sources. Returns a status (match, multiple_matches, possible_matches, no_match, need_location), a "say" sentence in the site's label wording, and matches with label, owner group, backers, PE stake and deal model, confidence, sources (headline, link, date), coverage and a correction link.
