What ZS Fund does

ZS Fund L.P. is a privately held middle-market private equity firm founded in 1985 by Ned Sherwood and headquartered at 630 Fifth Avenue in New York City. The firm invests in privately held or closely held companies generating between $4 million and $30 million in annual operating profit, with a particular focus on situations where owners need liquidity, estate planning solutions, management transitions, minority capital, or industry consolidation support. The core proposition is custom-tailored transaction structuring that allows business owners to retain a significant ownership stake and operational independence while addressing personal or shareholder objectives — a "win-win" model in which original owners share in post-transaction value creation via a "second bite at the apple." ZS positions itself as a constructive operating partner, citing case studies such as American Reprographics (38 add-on acquisitions in 30 months, revenue scaled from $75M to $300M) and Market Facts (market capitalization grown from $30M to over $200M prior to merger with Aegis Group plc).

The firm is run by a five-person partnership consisting of Founder Ned Sherwood and partners Bob Horne (joined 1992, ex-Salomon Brothers / Smith Barney), Nick Burger (joined 2000, ex-Merrill Lynch), Mark Hewett (joined 2021, ex-BNP Paribas), and CJ Carey (joined 2025, ex-Canaccord Genuity). Total headcount is reported in the 11–50 range, consistent with a boutique middle-market operation. Recent disclosed portfolio activity includes the 2016 acquisition of Amerijet International and the July 2023 acquisition of Lily Transportation Corp., supplemented by an approximately $115 million fund close in July 2023.

ZS Fund generates economics through traditional private equity returns — management fees on committed capital and carried interest on realized exits — with no standardized pricing or productized offering. Deal sourcing is conducted entirely through personal referrals, professional advisor networks, and direct outreach to company owners meeting investment criteria; the firm operates with no formalized marketing channels, no public revenue disclosure, and no external parent or institutional ownership structure. Operating geographies are reported as United States only, though the firm has prior experience with international investments (notably a majority interest in Hong Kong-based Sanda Kan Industrial Ltd. acquired in the mid-2000s).
