What Participant does

Participant Capital (legal entity: Participant, LLC) is a privately held global merchant bank founded in 2014 and headquartered in New York, with additional offices in Boston and London. The firm advises leading single family offices, select pension and sovereign wealth funds, and family-owned or privately held businesses on mergers and acquisitions, debt and equity placement, strategic advisory, and fund formation. Differentiated offerings include direct-investing programs — Private Equity Programs, Venture Capital Programs, Co-Investment Sourcing, and Family Office Formation — that leverage a curated network of more than 500 of the world's largest family offices and long-term investors.

The firm generates revenue primarily through transaction-based fees on M&A and capital-placement mandates, supplemented by recurring strategic advisory retainers and selective fund-formation engagements. There is no proprietary technology platform; services are delivered by founding partners Sean Costello (Managing Partner), Michael Kurdziel (Managing Partner), Daniel Costello (Managing Partner), and Karen Mitchell (Chief of Staff, London), each bringing prior senior experience at Morgan Stanley, Lehman Brothers, Barclays, RBC, Merrill Lynch, and News Corp. Securities offerings are executed through a third-party arrangement with Hollister Associates, LLC (Member FINRA, Member SIPC).

Go-to-market is relationship-driven: invite-only, off-the-record Family Office Summits hosted in London (May 2019) and New York (May 2018) in partnership with Bloomberg serve as the principal top-of-funnel channel, with warm introductions among the family office community feeding mid-funnel deal flow. The firm reports serving clients and completing deals across the United States, Canada, the United Kingdom, Ireland, India, Thailand, and Australia, and cites deal value benchmarks including more than $1B in transactions led by Kurdziel, $2.5B+ under Daniel Costello's leadership at News Corp, and $75M+ of financing arranged for DealerTrack prior to its 2005 IPO.

Scale indicators5 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• Allen & Company: Highly selective, relationship-driven boutique merchant bank that famously convenes the Sun Valley conference. A close analogue to Participant's invite-only Family Office Summits and its emphasis on private, off-the-record dialogue among principals of large family-controlled enterprises.
• Centerview Partners: Boutique independent advisory firm founded by former top-tier investment bankers. Closely comparable to Participant in business model (M&A and capital advisory, relationship-driven, principal-led) and in serving high-net-worth and institutional clients, though Centerview typically operates at substantially larger deal scale.

Broad incumbents

• Rothschild & Co: Global advisory house with a heritage of advising family-controlled and long-term capital. Shares Participant's emphasis on private, multigenerational clients and long-term capital, and competes for cross-border M&A and family-capital advisory mandates.
• Perella Weinberg Partners: Independent advisory firm providing M&A, capital placement, and restructuring advice to corporates, sponsors, and family-controlled businesses. Comparable in founder-led model and emphasis on long-term capital, but with deeper sector franchises and larger deal scale than Participant.
• PJT Partners: Independent advisory firm offering M&A and capital placement to a mix of family offices, corporates, and institutional investors. Overlaps with Participant in capital placement and family-capital advisory but operates at much broader scale.
• Moelis & Company: Independent, founder-led global advisory firm providing M&A, capital markets, and strategic advisory. Comparable in boutique, principal-driven origins and service mix, though Moelis is much larger and more diversified across sectors and geographies.
• Lazard: Global financial advisory and asset management firm with a long-established family office and M&A advisory franchise. Competes head-on with Participant for placement and advisory mandates from family offices and long-term investors, but at materially larger scale and broader service menu.
• Evercore: Independent investment banking advisory firm with deep M&A and capital placement capabilities. Comparable to Participant in core advisory service offering and target client overlap (family offices, institutional investors, private businesses), but with far broader coverage and public-company advisory strength.

Emerging players

• Tiger 21: Membership-based peer organization for high-net-worth investors that hosts roundtables, investment education, and curated peer deal sharing. Adjacent to Participant's Family Office Summits in that it aggregates UHNW investors for knowledge exchange and potential co-investment, though without the M&A execution capability.
• Cambridge Associates: Global investment advisory firm serving endowments, foundations, pensions, and family offices on private investment sourcing and portfolio construction. Overlaps with Participant's investor-side advisory and direct investment program work for family offices, but is asset-allocation oriented rather than transaction-execution oriented.
