Expedition Growth Capital

Founder and Managing Partner Oliver Thomas leads investment strategy and portfolio development. He works alongside Partners Will Sheldon, based in London, and Steve Twomey, who heads the Boston office. The three-partner structure governs investment decisions and board representation for the portfolio.

Expedition leads majority and significant minority growth-stage rounds in bootstrapped software and AI companies. The firm serves on portfolio company boards, with named partners and principals holding board director or observer seats at companies such as Dougs, Lempire, Omilia, Rentman, Ringover, and Xensam.

Oliver Thomas spent six years as a senior investment professional at Summit Partners in London before joining HgCapital and later founding Expedition. Partner Steve Twomey spent twelve years at Summit's Boston office. The firm's investment cadence and operational rigor reflect that growth-equity heritage, though Expedition operates independently with its own fund structure.

The firm focuses on companies headquartered in Europe and North America. With offices in London and Boston, Expedition targets portfolio companies with global ambitions, but its investment mandates center on those two regions.

Expedition maintains an in-house data and research team, led by a Head of Data & Research with a computational finance and molecular neurobiology background, that builds proprietary data platforms and automation workflows for thematic sourcing. The firm also leverages its operating advisor network and founder community for origination.

The Expedition Operations Group is the firm's in-house value-creation arm, staffed by Vice Presidents of Portfolio Operations and a roster of Operating Advisors with senior leadership experience at companies such as Darktrace, HubSpot, Unit4, Gong, and IFS. They work alongside portfolio company management on go-to-market, product, international expansion, and M&A — without replacing founder-led execution.

Fund III closed in April 2026 at $375 million in a first and final close. This brought the firm's total assets under management to over $500 million. The fund continues the firm's mandate of backing bootstrapped, capital-efficient software and AI companies across Europe and North America.
