Lincoln Frank

Lincoln E. Frank is the founder and Managing Partner of Quad Partners, a New York–based private equity firm he co-founded in 2000 with Daniel Neuwirth. Quad invests exclusively in the education sector and is one of the most active dedicated education investors in the U.S. Over its history the firm has raised well over $1 billion across multiple funds and has backed more than 60 education companies as platforms or add-on acquisitions. Frank is responsible for the overall management of the firm and has led investments across Quad's education portfolio.

Before founding Quad, Frank held a series of senior finance and legal roles. He served as Chief Operating Officer of J.P. Morgan Capital Corporation, worked as an investment banker at Goldman, Sachs & Co., and practiced law as an attorney at Skadden, Arps. This combination of legal, banking, and principal-investing experience underpins Quad's operationally intensive, education-specialized approach.

Frank holds a B.A. from Wesleyan University, a J.D. from the University of Pennsylvania Law School, and a master's degree (LL.M.) from the University of Cambridge. Outside of Quad, he has served as Chair of the Board of Directors of The New York Society for the Prevention of Cruelty to Children, and he sits on the board of Quad portfolio company Ruffalo Noel Levitz, a higher-education enrollment-management and fundraising firm.

Note: the stub data describing Frank as an "angel investor" focused on "seed rounds" appears inaccurate. Verified sources consistently describe him as the founder and Managing Partner of an institutional education-focused private equity firm that does growth-equity and control transactions, not individual angel/seed checks.

• Sector specialist: Quad invests only in education and workforce development, spanning edtech, tech-enabled education services, and site-based/physical education businesses across preK-12, higher ed, corporate training, and lifelong learning.
• Stage & structure: Lower-middle-market private equity — growth equity and control buyouts of established, revenue-generating companies, plus add-on acquisitions to build platforms (not seed/angel investing).
• Target profile: Owner-operated, growth-oriented education companies, reportedly with up to ~$100M in revenue, where Quad believes its industry and operational expertise can drive value creation.
• In their words: On closing Fund VI, Frank emphasized "the longstanding partnership with our investors" and the firm's mission of "building high-quality education companies," reflecting a relationship-driven, long-hold approach.
