Stonebridge is a private investment firm backed by family office capital.
We combine institutional-scale resources with entrepreneurial agility, partnering exclusively with a select group of founders in our core thematic areas. Our investments span the full company lifecycle—from launching ventures in-house to backing high-growth and pre-IPO market leaders—with a focus on industries being transformed by technology.
Unlike conventional fund managers, we are active builders, leveraging our global network, flexible capital, and hands-on operational support to unlock growth. Every company in our portfolio matters, and our highly selective approach has consistently delivered top-decile returns while creating exceptional outcomes for founders and enduring value for all stakeholders.
