One8 Foundation

One8 Foundation

One8 Foundation was established in 1997 by Jonathon Jacobson and Joanna Jacobson. The endowment originated from proceeds of Highfields Capital Management, the hedge fund Jonathon Jacobson led until 2021. The foundation operates as a venture philanthropy vehicle that pairs grants with direct consulting to grantees. The foundation allocates across private equity holdings, public equities, and direct program investments. Asset-class exposure includes venture capital commitments through vehicles such as WestCap Strategic Operator Fund and early-stage positions in Lendbuzz and Juniper Square. Geographic reach centers on the United States with additional exposure to Israel through holdings such as WINN.AI and Obligo Technologies. Confirmed positions include ZoomInfo Technologies, where HighSage Ventures entities hold stakes reported at 5.3 percent to 6.7 percent, and PennyMac Financial Services. The organization maintains 28 professionals and directs operations from its Boston headquarters. HighSage Ventures LLC serves as investment advisor. One8 Foundation participates in the Jewish Funders Network and Grantmakers for Education. In April 2026 the foundation spoke at the ASU+GSV Summit on education innovation and AI applications in schooling. One8 Foundation maintains a hybrid governance model that integrates family principals with an external investment advisor and program staff. This setup separates philanthropic deployment from the original hedge-fund operations while preserving direct oversight by the founding principals through trustee and president roles.
