Ownership & Acquisition History
No evidence of private equity ownership was found; available public records and the company’s own materials indicate Black Cat Plumbing (Portland, OR) is an owner-operated business associated with Michael (Mike) Perrotti.
Notes
- Disambiguation: multiple businesses use the name “Black Cat Plumbing”; this conclusion applies to the Portland, Oregon business operating at blackcatplumbing.com (not the Milwaukee-area business at blackcatplumbing.net).
- Ownership/operations signals: the company website states it was founded in 2006 by Mike Perrotti and prominently attributes statements to him, consistent with a founder-led local operator model.
- Domain/identity corroboration: WHOIS/RDAP listings for blackcatplumbing.com show a Portland address and contact email for “mike@blackcatplumbing.com,” and identify “Perrotti, Michael” as the technical contact—supporting the founder/operator identity trail.
- Municipal/public record corroboration: a City of Portland eFiles document lists “BLACK CAT PLUMBING INC” at the same SE 72nd Ave address seen in other sources, supporting the operating entity identity.
- Registry escalation attempt: the Oregon Secretary of State’s official “Find a Business” portal routes to an entity search application (egov.sos.state.or.us), but direct access to that search endpoint was blocked by a cybersecurity gate during this run (support-ID wall), preventing retrieval of the SOS entity-detail page (registered agent/officers) from the primary registry interface.
- Despite the SOS search block, no reputable sources (deal announcements, PE portfolio pages, SEC filings, or major business press) surfaced indicating a PE sponsor/parent for this Portland, OR plumbing contractor.
- Name ambiguity: there are multiple companies using the name “Black Cat Plumbing” (e.g., a Milwaukee, Wisconsin business at blackcatplumbing.net founded by different individuals), so this report is specifically for the Portland, Oregon company operating at blackcatplumbing.com.
- Ownership: the company website describes the business as founded by (and prominently associated with) Mike Perrotti, and BBB lists “Mr. Michael Perrotti, President,” with no mention of any parent company or sponsor—no PE sponsor was identified in reputable sources reviewed.
- No transaction/portfolio evidence: web research did not surface credible acquisition/portfolio pages or deal announcements indicating PE ownership for the Portland, OR company.
