South African venture capital firm Grindstone Ventures has launched a ZAR 500 million ($31.3 million) fund targeting technology-enabled businesses from seed through Series A, as investors look to address one of the biggest gaps in Africa’s startup funding pipeline.
The fund, led by Managing Partner Thandiwe Maqetuka, is designed to provide capital to businesses that have moved beyond the earliest stages of development but are not yet ready for larger institutional funding rounds.
Grindstone Ventures plans an initial ZAR 150 million ($9.4 million) first close and expects to build a portfolio of between 15 and 20 companies. The fund will focus primarily on South African businesses while making selected investments elsewhere in Africa.
Targeting the funding gap
The stage between seed funding and Series A has become an important challenge for African startups.
Many young companies can raise enough capital to develop a product and establish early commercial traction, but securing the next round can be considerably more difficult.
Grindstone Ventures was created around this problem.
The firm’s existing investment strategy focuses on post-seed equity and quasi-equity investments in innovation-driven and technology companies with strong intellectual property and significant growth potential.
Its model is closely connected to the Grindstone Accelerator, which prepares startups for investment by providing support around strategy, networks, funding and market access.
From accelerator to investment
Grindstone’s approach is unusual in that its accelerator effectively serves as part of the investment pipeline.
Companies that participate in the Grindstone growth programme can become candidates for investment, allowing the fund to assess businesses over time rather than relying solely on a conventional investment process.
The organisation says its accelerator has helped build a pipeline of companies that can become investment-ready and move toward larger funding rounds.
That approach is particularly relevant in African markets, where investors often have limited visibility into young companies and where early-stage capital remains unevenly distributed.
A focus on technology and growth
Grindstone Ventures is sector agnostic within technology and innovation.
Its investment themes include post-seed companies on a growth trajectory, innovation-led technologies, co-investments and additional funding to support expansion and follow-on rounds.
The fund’s existing portfolio illustrates the breadth of that approach, with investments spanning smart infrastructure, agricultural technology, healthcare, payments, logistics and software.
Companies previously backed by Grindstone include Locstat, Welo Health, AgrilogiQ and Sticitt.
Diversity remains part of the strategy
The new fund also carries forward Grindstone’s emphasis on diversity.
The firm says its investment mandate is built around balanced portfolios, with a focus on both gender and broader diversity. The new vehicle is targeting at least 50% black-owned companies.
That matters in a venture market where access to capital remains uneven and where founders from underrepresented backgrounds can face additional barriers to raising institutional funding.
Why the fund matters for Africa
The significance of the new fund goes beyond its $31.3 million headline figure.
Africa’s technology ecosystem does not simply need more seed capital. It needs more investors willing to support companies through the difficult stage between proving that a business works and building it into a large regional or global company.
That is where post-seed and pre-Series A funding becomes particularly important.
Grindstone’s first fund, launched in 2021, was established specifically around this gap and initially targeted predominantly South African technology startups. That fund was valued at $6.5 million at launch.
The new $31.3 million vehicle represents a significant increase in the capital available through the Grindstone platform.
South Africa remains the launchpad
Although the fund is being positioned as an African vehicle, South Africa remains its primary market.
That reflects the country’s relatively mature venture ecosystem, but it also gives Grindstone a potential base from which to identify companies capable of expanding into other African markets.
For founders, the most important question will ultimately be whether the new capital can help promising companies move from early traction to sustainable scale.
For the broader African technology ecosystem, however, the fund represents another sign that investors are increasingly looking beyond the continent’s earliest startup stages.
The next phase of Africa’s technology story may depend less on how many startups are created and more on how many can successfully make the difficult transition from startup to scaleup.
