## About

Highsage Ventures was established in 2019 by Jonathon S. Jacobson. The firm manages capital originating from the founder’s prior hedge fund, Highfields Capital Management. It operates as a single-family office with a permanent-capital structure that supports long holding periods. The investment approach mixes direct co-investments, SPVs, and opportunistic growth equity. Asset classes include venture capital, private equity, and public equities. Confirmed positions include Re:Build Manufacturing, PennyMac Financial, IAC, MGM Resorts, OakNorth, Hilton, Workday, ZoomInfo, Mark43, FIGS, Amperity, Optibus, and Street Smarts VR. The firm targets growth-stage and expansion companies in North America and Europe while maintaining exposure to select opportunities in the Middle East and Oceania. Highsage maintains a compact team led by Jennifer L. Stier as President and Partner and Owen M. Wurzbacher as Chief Investment Officer and Partner. The firm occupies headquarters at 200 Clarendon Street in Boston. No additional offices are disclosed. Philanthropic activity runs through the One8 Foundation, which operates separately from the investment vehicle. No operational events from the last 24 months appear in public records. The permanent-capital mandate creates a structural difference from typical limited-life funds. This structure allows Highsage to remain invested through extended operating cycles and to participate in both private growth rounds and public-market holdings without redemption pressure.
