Longworth Venture Partners

Co-founders Paul Margolis and Jim Savage serve as the firm's general partners and lead investment decisions. The partnership structure is compact, which means each portfolio company typically receives direct attention from one or both named partners at the board level. Margolis and Savage have worked together since founding the firm in 1999.

Longworth concentrates on early-stage and growth-stage venture investing, commonly leading or co-leading Series A and Series B rounds. The firm also reserves capital to participate in follow-on financings as portfolio companies scale. This stage focus has been consistent across multiple fund vintages.

The firm invests primarily in enterprise software, digital health, fintech, and applied artificial intelligence and machine learning. Past portfolio companies span cloud infrastructure, data analytics, and insurance technology, reflecting a preference for technically complex businesses selling to enterprises and healthcare organizations.

While the majority of the firm's deal flow originates in the Northeast and broader U.S. technology markets, Longworth has made selective investments in European technology companies. The partnership does not maintain non-U.S. offices and conducts international investing from its Waltham, Massachusetts headquarters.

Longworth benefits from its location in Waltham and the broader Boston technology corridor, which provides access to startups emerging from MIT, Harvard, and the region's network of research hospitals and enterprise technology clusters. The firm's two-decade track record and general partners' personal networks also generate repeat founder and co-investor referrals.
