Cyprium Investment Partners

What Cyprium Investment Partners does

Cyprium Investment Partners is a Cleveland-headquartered private investment firm founded in 1998 that specializes in providing non-control capital to profitable, middle-market companies across the United States and Canada. The firm deploys mezzanine debt, preferred equity, and minority common equity in check sizes of $5 million to $60 million, targeting companies with $4 million to $40 million in EBITDA. Cyprium operates two primary fund vehicles: Cyprium SBIC I LP (focused on $4-10M EBITDA companies with $5-15M investments) and Cyprium Investors VI LP (focused on $10-40M EBITDA companies with $10-60M investments). Since inception, the firm has invested over $2 billion in more than 100 platform companies spanning manufacturing, distribution, industrial services, food and beverage, healthcare, business services, and aerospace.

The firm's core differentiator is its non-control capital model, which allows founders, families, entrepreneurs, and management teams to retain economic and operational control while accessing growth and liquidity capital. Cyprium structures subordinated debt with PIK features, preferred equity, and common equity to support use cases including acquisition financing, management buyouts, ESOP transitions, shareholder liquidity events, refinancings, and growth capital. The firm operates a direct origination model, sourcing deals through referrals from investment banks, lenders, accounting firms, law firms, and its network of industry executive advisors, rather than through broad auctions.

Cyprium generates revenue from two streams: (1) recurring fund management fees on its two active funds, and (2) transaction-based carried interest from successful exits of portfolio investments. The firm maintains offices in Cleveland (headquarters at 200 Public Square), New York (1140 Avenue of the Americas), and Chicago (77 West Wacker Drive), supported by a team of 11-50 employees including five partners and multiple principals and vice presidents. Capital is sourced through a relationship-based origination system built over 25+ years, supplemented by whitepaper content marketing and direct outreach to founder-, family-, and management-owned businesses.

Direct peers

• Key Principal Partners: Cyprium's historical lineage traces to Key Principal Partners, and the firm continues to operate as a non-control capital provider to middle-market companies using subordinated debt and minority equity — the closest direct strategic and product analog.
• Regis Capital Partners: Founded by John Sinnenberg in 1996 as the predecessor to Cyprium, Regis continues to provide mezzanine debt and minority equity to lower middle-market companies — virtually identical strategy and target customer.
• Golub Capital: Major middle-market direct lending and mezzanine provider with overlapping client base in non-control capital and broadly similar EBITDA band; one of Cyprium's most direct private credit competitors.
• Madison Capital Funding: Middle-market focused debt provider offering unitranche, second lien, and mezzanine financing to PE sponsors and non-control situations, directly overlapping Cyprium's lower/middle-market positioning.
• NXT Capital: Provides senior and junior capital to middle-market companies; competes with Cyprium for the same non-control and PE-sponsored financing opportunities.

Broad incumbents

• Main Street Capital: Publicly traded BDC making debt and equity investments to lower middle-market companies — adjacent to Cyprium's SBIC strategy with overlapping EBITDA band and structural product offerings.
• Prospect Capital: Large public BDC/private credit platform with middle-market mezzanine, senior debt, and equity investments, overlapping with Cyprium's product mix at a much larger scale.
• Audax Group: Middle-market private equity firm that also operates debt and continuation vehicles serving the same lower/middle-market companies targeted by Cyprium.
• H.I.G. Capital: Global alternative investment firm with dedicated mezzanine, debt, and equity funds serving middle-market companies, frequently cited as a peer from VP Adam Martin's prior experience.
• Blackstone Credit (formerly GSO Capital): Largest alternative credit platform with middle-market direct lending and mezzanine strategies, increasingly competing for the same non-control capital opportunities as Cyprium.
