Maranon Capital
Maranon Capital is a Chicago-based private credit manager founded in 2002 specializing in mezzanine debt for middle-market sponsored companies.
Maranon Capital
Ian Martin and David McDonough launched Maranon Capital in 2002 to fill a specific gap in the middle market: subordinated and mezzanine debt for sponsor-backed companies. The firm operates from Chicago and invests nationally across the United States. Maranon deploys capital primarily through mezzanine and subordinated debt instruments, with the flexibility to structure unitranche, second-lien, and preferred equity alongside traditional subordinated notes. Investment targets are middle-market companies with $4 million to $20 million in EBITDA, typically in sponsor-led recapitalizations, leveraged buyouts, and acquisitions. Sector coverage spans business services, healthcare, industrial technology, and consumer products. The firm has historically managed capital through commingled private credit funds, drawing commitments from institutional limited partners. Maranon has deployed multiple fund vintages over two decades. The firm raised its fourth mezzanine fund, Maranon Mezzanine Fund IV, L.P., a vehicle targeting the same subordinated debt strategy across US middle-market sponsor transactions. The team manages portfolio exposure across a diversified issuer base, avoiding concentration in any single sponsor or sector. Unlike larger credit platforms that layer senior, unitranche, and subordinated strategies under one roof, Maranon remains dedicated to the subordinated portion of the capital stack. This structural choice gives sponsors a dedicated counterparty for junior capital, reducing the conflicts that arise when a single lender controls multiple layers of the same borrower's balance sheet.

Frequently asked questions
What type of debt does Maranon Capital provide?
Maranon Capital provides subordinated and mezzanine debt, along with structured junior capital including second-lien term loans, preferred equity, and unitranche notes. The firm targets investments ranging from $10 million to $75 million per transaction, typically in companies generating between $4 million and $20 million in EBITDA. Maranon's mandate centers on the junior portion of the capital stack, allowing senior lenders to hold the first-out position.
What is Maranon's relationship with private equity sponsors?
Maranon works exclusively with private equity sponsors, providing junior capital for leveraged buyouts, recapitalizations, refinancings, and add-on acquisitions. The firm acts as a financing partner rather than a control investor, taking minority equity co-investments only when attached to a debt package. This sponsor-only focus means Maranon does not lend directly to founder-owned or family-held businesses outside a sponsor process.
How large is Maranon Capital by assets under management?
Maranon Capital does not publicly disclose its assets under management. The firm raises capital through a series of commingled mezzanine funds targeting institutional investors. Without a published AUM figure, the firm's scale is best inferred from its deal size range and sponsor coverage across the US middle market.
Does Maranon Capital participate in fund commitments or only direct deals?
Maranon does not operate as a fund-of-funds or commit capital to other private credit managers. All investments are structured as direct loans to portfolio companies, with Maranon acting as the originating and negotiating counterparty alongside the private equity sponsor. The firm does not purchase secondary loan portfolios or participate in broadly syndicated loan facilities.
What investment stages does Maranon Capital typically target?
Maranon targets mature, cash-flow-positive middle-market companies rather than venture-stage or growth-equity businesses. The firm requires a minimum of $4 million in EBITDA at entry, with borrowers typically holding leading positions in defensive or non-cyclical industries. Maranon does not invest in startups, pre-revenue companies, or turnarounds without near-term free cash flow.
Where does Maranon Capital source its deal flow?
Deal flow comes entirely through private equity sponsor relationships. Maranon does not market directly to business owners or run proprietary origination outside the sponsor channel. Over two decades, the firm has built a network of repeat relationships with middle-market buyout funds, generating pipeline from sponsor-led processes rather than broad auction platforms.
Is Maranon Capital a single family office?
No. Maranon Capital is an institutional private credit manager raising third-party capital through commingled funds. The firm was co-founded by Ian Martin and David McDonough as an independent partnership and has no disclosed connection to a single-family wealth source.
