HighSage Ventures is a Boston-based investment firm launched in 2019 by Jonathon S. Jacobson and led by Managing Director Owen M. Wurzbacher. Backed by permanent capital, the firm partners with experienced operators to build exceptional per share value over ten years or more. The leadership group includes Shawn M. Campbell, Jonathon S. Jacobson and Jennifer L. Stier, supported by an advisory board featuring Bill Helman and Brian Rogers. Experts at HighSage engage directly with company leaders, offering feedback and market analysis to inform critical decisions. In addition to funding, the firm channels returns to charitable causes, reflecting a sense of purpose alongside financial performance.
The permanent capital structure allows HighSage to resist typical fund lifecycles, supporting patient decision making and sustained collaboration with founders. The firm maintains a concentrated portfolio of competitively advantaged businesses held over a long horizon, while also providing growth capital to select software, consumer and financial services companies with attractive unit economics. As a sector-agnostic investor, HighSage deploys capital through a range of securities, including common equity, preferred shares and convertible debt in private and public settings. Portfolio companies benefit from strategic guidance on expansion, talent recruitment, customer introductions and acquisition planning, drawing on the team’s deep market expertise and network.
While many investments focus on software, consumer and financial services ventures, HighSage has shown an interest for sustainable energy solutions. A notable example is About:Energy, a London-based company developing battery measurement, modeling and data tools aimed at extending system lifetimes and reducing material needs. The firm has also backed SINAI Technologies, whose platform supports corporate carbon management and decarbonization strategies. Although only one dedicated hardware-oriented battery investment is public, these stakes illustrate a willingness to back technology that addresses environmental challenges.
