The firm has executed more than twenty named platform and add-on acquisitions since 2017 across sectors including automotive aftermarket, building products, consumer products, food packaging, HVAC, industrial manufacturing, and quick-lube services; notable holdings include Waupaca Foundry, Valtir (formerly Trinity Highway Products), Japs-Olson, Texas Pride Trailers, Cast-Crete, and the announced Jiffy Lube acquisition from Shell.

Monomoy Capital Partners competitors and assessment
Company assessmentDirect peers
- KPS Capital Partners: KPS Capital Partners is a middle-market private equity firm focused on operational turnarounds and carve-outs in industrial and manufacturing businesses. It is a direct peer — both founders (Dan Collin, Lee Mlotek) and multiple Monomoy team members previously worked at KPS, and the investment thesis (industrial/distribution/services, operational value creation, family/PE carve-outs) closely matches Monomoy's playbook.
- Wellspring Capital Management: Wellspring is a middle-market private equity firm investing in consumer, industrial, and business services companies. Monomoy Managing Director Mel Bartoul spent over 11 years at Wellspring, and the firm shares Monomoy's focus on operationally-intensive middle-market carve-outs and platform builds in similar sectors.
- Windjammer Capital Investors: Windjammer is a middle-market PE firm targeting industrial, distribution, and consumer businesses, with explicit operating partner involvement. Senior Operating Executive Helen Ruth was previously an operating director at Windjammer, and Monomoy's stated strategy (industrial/consumer mid-market, operating-led value creation) directly mirrors Windjammer's approach.
- Platinum Equity: Platinum Equity is a global private equity firm specializing in operations-intensive carve-outs and complex situations in industrial, distribution, and business services. It is highly comparable to Monomoy given the shared focus on carved-out/non-core corporate divestitures and active operational improvement, though Platinum is materially larger in AUM.
- American Industrial Partners: American Industrial Partners is a private equity firm focused exclusively on industrial businesses, including manufacturing, distribution, and industrial services. It is one of the closest sector- and size-comparable peers to Monomoy, with an operating-partner model and similar middle-market EV targets.
- Wynnchurch Capital: Wynnchurch is a middle-market PE firm investing in operationally intensive industrial, business services, and consumer transactions. Recently acquired Monomoy's Astro Shapes exit (Jan 2025), reinforcing how directly competitive and overlapping the two firms' deal sourcing and investment theses are.
- Sun Capital Partners: Sun Capital Partners is a middle-market private equity firm focused on operationally intensive investments in industrial, consumer, and business services companies. Comparable size and sector overlap with Monomoy, including use of operating partners to drive value creation in middle-market carve-outs and family-owned businesses.
- Staple Street Capital: Staple Street Capital is a middle-market PE firm targeting operationally complex carve-outs and control investments in industrial and business services. Ben Humphreys held operating/CFO roles at Staple Street prior to joining Monomoy; the firms share the operating-led, industrial-mid-market thesis at comparable fund sizes.
Broad incumbents
- Cerberus Capital Management: Cerberus is a large, diversified alternative asset manager with substantial private equity and credit operations in industrial, consumer, and services companies. Multiple Monomoy Operating Team members joined from Cerberus (Ethan Klemperer was President of Cerberus Operations & Advisory; Ben Humphreys held operating/CFO roles at Cerberus). Cerberus is a broader incumbent with overlapping operating-PE philosophy but materially larger AUM.
- Apollo Global Management: Apollo is a global alternative asset manager with major PE buyout, private credit, and hybrid value strategies that overlap with Monomoy's industrial mid-market focus and growing credit platform. Apollo is a broad incumbent — Monomoy occasionally competes against Apollo for the same carve-out or take-private targets, particularly as Apollo has moved down-market in direct lending.
