Saybrook Fund Advisors

Saybrook focuses almost entirely on corporate carve-outs — acquiring non-core divisions or subsidiaries from large public and private companies. The firm also invests in founder-owned businesses where operational transition and professionalization are required. Its deal sizes range from approximately $20 million to $100 million of equity per transaction.

Saybrook targets a hold period of ten to twelve years, which is approximately double the industry average for middle-market private equity. This extended timeline supports turnarounds that require management rebuilds, systems overhauls, and new product development that five-year funds cannot execute.

Investments are led by the firm's Managing Directors: Jonathan Rosenthal, Jonathan Gimbel, and William N. Schein. The firm operates with a flat partnership structure and does not rely on a traditional external investment committee.

Saybrook maintains a dedicated corporate development outreach function that builds relationships with business development and strategy groups inside Fortune 500 companies. This approach allows the firm to identify and negotiate carve-out transactions before divisions are broadly marketed through sell-side auctions.

Saybrook invests in industrial technology and services, business services, and healthcare — specifically areas like specialty manufacturing, testing and inspection, and outsourced healthcare logistics. The firm avoids consumer products, retail, and deeply regulated financial services.
