Grindstone Ventures, a South African venture capital firm, has launched a new fund worth approximately $31.2 million, or R500 million, designed to carry African technology businesses from early seed through a successful Series A and beyond. This is not just another fund announcement. It directly responds to one of the most significant structural problems in Africa’s startup ecosystem, and it carries the weight of lived experience from the people behind it.
The People and Partnerships Behind the Money
The new fund is led by Thandiwe Maqetuka, the chief executive of Grindstone Ventures, and was established in partnership with two respected names in African venture building: Knife Capital and Thinkroom. This combination matters because it brings together different kinds of expertise. Knife Capital is a well-established venture capital firm known for its hands-on approach to scaling businesses, while Thinkroom brings deep experience in entrepreneur development and acceleration. Together, they have built a structure that does not simply write cheques and hope for the best. The fund is targeting an initial close of R150 million, which is roughly $9.3 million, with plans to ultimately build a portfolio of between fifteen and twenty businesses. Most of these investments will go to South African companies, but the fund is keeping its eyes open for exceptional opportunities in other parts of the continent as well. The leadership of a woman in a sector that has historically been dominated by men is also a quiet but important signal about the kind of future Grindstone Ventures wants to help build.
Understanding Africa’s Missing Middle
To appreciate why this fund matters, you need to understand the problem it is trying to solve. Keet van Zyl, co-founder of Knife Capital, put it plainly when he said that the evolution from seed funding to Series A remains one of the clearest gaps in the African venture ecosystem. In plain terms, this is the stage where a startup has moved past the initial idea and proven that customers will actually pay for its product or service. It has traction. It has early revenue. But it still needs significant capital to hire more people, expand into new markets, strengthen its technology, and build the kind of operational backbone that large investors expect to see. Yet at this exact moment, the funding often dries up. African technology funding as a whole strengthened in 2025, but seed funding actually declined for the third consecutive year. This leaves many promising businesses undercapitalised just as they need fuel the most. Thandiwe Maqetuka describes this precise moment as Africa’s missing middle. The fund’s opportunity, she explains, is not simply to provide more capital, but to identify exceptional businesses earlier, invest at a point where capital remains scarce, take meaningful ownership positions, and work actively with founders to build companies capable of scaling, attracting institutional capital, and ultimately delivering realisable returns. That is a fundamentally different approach from the passive investing that has sometimes characterised venture capital in Africa.
How the Fund Will Work in Practice
The fund will invest from the seed stage all the way through to Series A, and it will reserve part of its resources to provide follow-on funding to the companies that perform best. This means that a startup that receives an initial investment and then demonstrates strong growth can expect additional support as it scales, rather than being left to fend for itself in the market. The strategy involves taking meaningful minority positions in businesses, which gives Grindstone Ventures both the incentive and the influence to actively help the companies it backs. The support goes far beyond money. Portfolio companies will receive hands-on assistance with strategy, governance, commercial growth, market access, future fundraising, and preparing for an eventual exit. This kind of operational support is often the difference between a startup that survives and one that thrives. The fund’s partners bring deep experience in venture investment, entrepreneur development, acceleration, and scaling technology businesses. More than one thousand businesses are screened annually through the wider Grindstone ecosystem, with around fifty participating in accelerator programmes each year. This gives the fund an unusually wide view of the pipeline of emerging African businesses, allowing it to spot talent and potential early, before the crowd arrives.

Focused on Real and Tangible Returns
One of the most striking things about this fund is its frank emphasis on exits. In the world of venture capital, it is possible for a fund to look successful on paper because the companies it has invested in have high valuations, even if no actual money has been returned to investors. Thandiwe Maqetuka is refreshingly direct about this. She says the portfolio has been deliberately designed around the realities of venture investing as they are focused on real and tangible returns. The first Grindstone Ventures fund invested in seven companies, including Locstat, Welo, and AgriLogiQ, which subsequently raised further equity funding from international investors. The firm is also finalising an exit from that first fund that it says will return capital to its investors. If that exit is successful, it will send a powerful message that African venture capital can deliver real results.
Creating Opportunities for Black and Female Entrepreneurs
Alongside its financial goals, Grindstone Ventures has made a clear commitment to broadening access to venture capital for groups that have historically been left out. The fund aspires for at least fifty per cent of its portfolio companies to be black-owned, while also pursuing gender-balanced representation among female founders and women in leadership roles. This is not simply a matter of charity or tokenism. It is a recognition that Africa’s entrepreneurial talent is spread across every community, and that the continent cannot afford to leave brilliant minds on the sidelines. Thandiwe Maqetuka puts it simply: investors should not have to choose between financial performance and building a more inclusive investment ecosystem. The fund’s commitment to inclusivity is embedded in its investment strategy, not bolted on as an afterthought. By actively seeking out businesses led by black entrepreneurs and women, Grindstone Ventures is helping to correct a historical imbalance in who gets access to capital, while also tapping into markets and perspectives that more traditional funds have often overlooked.
What This Means for African Startups and the Continent’s Economy
For founders across Africa, this fund represents more than just a new source of money. It represents a partner that understands the unique challenges of building a technology business on the continent. The fund’s willingness to invest at the seed stage, when capital is scarce, and its commitment to providing follow-on funding as companies grow, means that startups can plan for the long term rather than constantly worrying about where the next round of funding will come from. The focus on market access is particularly valuable. Many African startups build excellent products but struggle to reach customers beyond their immediate geography. Grindstone Ventures’ network and experience can help open doors to new markets, both within South Africa and across the continent. The emphasis on governance and exit readiness also prepares founders for the kind of scrutiny and structure that larger institutional investors and potential acquirers will expect. In a broader sense, this fund is a bet on Africa’s future. It is a bet that the continent’s technology sector is not just a collection of interesting experiments, but a source of real economic value. It is a bet that African entrepreneurs can build companies that compete on a global stage. And it is a bet that the missing middle, that frustrating gap between seed funding and Series A, can be bridged with the right combination of capital, expertise, and patience.
A Signal of Growing Confidence
The launch of a $31.2 million fund by a female-led team in partnership with established players like Knife Capital and Thinkroom is a signal of growing confidence in Africa’s technology ecosystem. It shows that investors are willing to commit serious resources to the continent’s entrepreneurs, not just at the earliest and riskiest stages, but through the critical growth phase where so many businesses falter. It also shows that there is a growing understanding of what African startups actually need to succeed, some of which includes strategic guidance, access to markets, help with governance, and a partner who is genuinely invested in their long-term success. Grindstone Ventures appears to understand this deeply. As the fund begins to deploy its capital and build its portfolio, it will be watched closely by founders, investors, and policymakers across the continent.
