Target first close: November 1, 2026.
The annual management fee applies to LP capital contributions. Full-duration management fees are paid at each investor’s closing, reducing capital available for investment at the outset. Permitted fund expenses further reduce investable capital and net returns. Fund investments are illiquid and may lose capital.
The 7 realized exits and 3.25x cash returned reflect prior transactions in companies sourced through Maven Scouts and MavenWERX, not investments made by Grind Ventures. Past outcomes do not predict future performance for this fund.
