Try Dealroom →, and is chasing a first close of R150m.
Why now? While African technology funding strengthened in 2025, Seed funding fell for a third straight year, leaving some startups undercapitalised as they try to scale. The fund aims to plug the gap between early commercial validation and institutional-scale investment.
What's the endgame? GrindstoneDealroom has a profile for this one. Try Dealroom → plans a portfolio of 15 to 20 businesses, primarily in South Africa with selective bets elsewhere on the continent. It will take meaningful minority positions, then concentrate follow-on capital behind its strongest performers.
The firm frames this as Africa's "missing middle." "Our opportunity is not simply to provide more capital, but to identify exceptional businesses earlier, invest at a point where capital remains scarce," Maqetuka said.

Those firms went on to raise further equity from international investors, and the fund is finalising an exit it says will return capital to investors.
Focus on exits: Maqetuka stressed the fund is built for liquidity from the start. "Paper valuations don't return capital to investors, exits do," she said. Grindstone will also support portfolio companies on strategy, governance, market access, and exit readiness.
Inclusion targets: The fund aspires for at least 50% of its portfolio companies to be black-owned, while pursuing gender-balanced representation among founders and leadership. More than 1,000 businesses are screened annually through the wider Grindstone ecosystem, with around 50 joining accelerator programmes each year.
The signal: As Africa's Seed pipeline thins, capital is shifting to the harder, later stage where startups stall out. Grindstone's concentrated, exit-focused approach reflects a maturing market where investors are prioritising realisable returns over headline valuations.
