Key Principal Partners

Key Principal Partners (KPP) was a private equity firm headquartered in Cleveland, Ohio, that specialized in providing mezzanine debt and equity capital to middle-market companies. Affiliated with KeyCorp, the firm targeted investments in a broad range of sectors, including manufacturing, distribution, consumer products, and healthcare services. KPP typically provided flexible capital solutions for management buyouts, recapitalizations, and expansion strategies for companies with revenues between $30 million and $500 million. The firm was known for its ability to offer non-control equity and subordinated debt, allowing business owners to retain majority ownership while accessing growth capital. While it maintained a portfolio that included healthcare and medical technology companies, KPP operated as a financial institution rather than a life sciences research entity. The firm is no longer actively making new investments and has transitioned into a legacy portfolio management phase.
