Yellow’s Series C Puts African Solar and Smartphone Finance Back in the Spotlight
South Africa-based Yellow has raised a Series C round to scale solar and smartphone financing across key African markets.
South Africa-based Yellow has raised an undisclosed Series C funding round, putting African asset finance back at the centre of the continent’s energy-access and digital-inclusion debate. The company, which finances pay-as-you-go solar home systems and smartphones for low-income customers, said the new capital will support expansion across key African markets after passing the milestone of more than one million customers.
Disrupt Africa reported on August 25, 2026, that the round was led by Convergence Partners, the same investor that led Yellow’s US$14 million Series B in 2023. Tech In Africa reported that Susquehanna Sustainable Investments also backed the Series C, while Yellow said the new phase would help scale its smartphone and solar-energy businesses, expand into new markets and build the infrastructure needed to serve millions more people across Africa.
The amount was not disclosed, but the strategic signal is clear. Investors are still willing to back African companies that sit at the intersection of essential services, embedded finance and last-mile distribution. Yellow is not selling a luxury product. It is financing practical assets: electricity through solar systems and connectivity through phones. In markets where upfront costs can block household adoption, that combination is economically important.
Why Yellow’s round matters
Yellow was founded in 2018 by Mike Heyink and Maya Stewart. Its model focuses on last-mile distribution and asset-backed credit. Instead of asking rural or lower-income customers to pay the full cost of a solar kit or smartphone upfront, the company uses a financing structure that lets customers spread payment over time. That is a critical difference in African markets where demand exists but household liquidity is limited.
The company says it has served more than one million customers and now operates across seven African countries, with more markets in the pipeline. Disrupt Africa listed Malawi, Zambia, Uganda, Rwanda, Madagascar, the Democratic Republic of Congo and Nigeria among the key markets targeted for expansion. Those markets are different in language, regulation, infrastructure and consumer behavior, but they share two major gaps: reliable power and affordable digital access.
That is why this funding round should be read as more than a startup announcement. It is part of a broader shift in African finance. Some of the most important consumer-finance products on the continent may not be cash loans. They may be financed assets that unlock income, education, communication, safety and productivity.
Solar and smartphones are connected
Energy access and digital access are often discussed separately. In practice, they are linked. A smartphone has limited value when a household cannot reliably charge it. A solar system has greater economic value when it powers communication, mobile money, learning, trade and small-business activity. Yellow’s business sits inside that relationship.
Across rural Africa, the phone is a financial tool, a market terminal, a classroom, a health-information channel and a work device. For traders, farmers, drivers, students and informal workers, access to a reliable device can change how quickly information moves and how safely payments are made. For households beyond dependable grid power, a solar home system can reduce reliance on candles, generators or irregular charging points.
The financing layer is therefore not just a payment trick. It is the mechanism that makes adoption possible. If a household cannot afford a lump-sum purchase, a pay-as-you-go product can turn a blocked need into a manageable recurring expense. The challenge is underwriting that customer responsibly and servicing the asset reliably after sale.
The role of credit scoring
Yellow uses AI-enabled credit scoring to assess customers and provide financing for essential products, according to Disrupt Africa. That matters because many customers in last-mile African markets have thin or nonexistent formal credit records. Traditional lenders often avoid them because the cost of assessment is high and the data is limited.
Technology can lower that barrier, but it also raises questions. Credit models need to be transparent enough to avoid unfair exclusion. They need strong data-protection standards. They must also be paired with practical customer support, because default risk is not only a data problem. It can be shaped by weather, household income shocks, local employment cycles, product durability and after-sales service.
For Yellow, the credibility of the model will depend on whether it can grow while keeping affordability, repayment discipline and customer trust in balance. A million-customer milestone is significant, but the harder test is operating at several times that scale without letting service quality fall.
Why investors are returning
Convergence Partners’ decision to lead another Yellow round is important because it suggests follow-on confidence, not only first-time curiosity. The investor already knew the company from the Series B round. Leading the Series C indicates that Yellow’s operating performance has been strong enough to justify deeper exposure.
For African venture capital, that distinction matters. The continent’s startup market has become more selective. Investors are asking harder questions about unit economics, margins, governance and paths to profitability. Companies that finance physical assets must be especially disciplined because they face inventory risk, logistics costs, repayment risk and working-capital pressure.
Yellow’s proposition is that asset finance can be commercially viable while serving customers who are usually ignored by mainstream credit. If that thesis holds, it can attract more patient capital into African energy access, device financing and productive consumer assets.
The markets to watch
Yellow’s expansion list includes some of Africa’s most strategically important access markets. Nigeria is the continent’s largest economy and population base, but it is also operationally complex. The Democratic Republic of Congo offers huge demand but difficult logistics and uneven infrastructure. Malawi, Zambia, Uganda, Rwanda and Madagascar each require local execution, distribution partnerships and regulatory adaptation.
That creates both opportunity and risk. Scaling across Africa is rarely a simple copy-and-paste exercise. A company must adapt pricing, payment behavior, field-agent networks, customer education and after-sales support market by market. The firms that succeed tend to combine technology with patient local operations.
Yellow employs more than 200 staff, according to Disrupt Africa. That human network is as important as the software layer. Last-mile finance is trust-heavy. Customers need to understand the product, the payment terms and the service promise. Agents and local teams often become the bridge between the platform and the household.
The 2030 target
Yellow has said it wants to reach 10 million customers with access to electricity and internet by 2030. That target is ambitious. Moving from one million to 10 million customers will require capital, distribution depth, operational controls and strong repayment performance. It will also require the company to navigate currency risk and the cost of importing devices and solar equipment.
But the ambition fits the scale of the problem. Africa’s energy-access gap and digital divide are not small market niches. They are structural constraints on productivity. If companies can finance essential assets responsibly, they can support household resilience while building large commercial platforms.
What this says about African tech
Yellow’s Series C also broadens the definition of African tech. The headline is not another payments app or enterprise software product. It is a company using technology, credit, distribution and physical assets to solve basic access problems. That hybrid model may become one of the continent’s most important startup categories.
The strongest African tech companies often do not look like their Silicon Valley counterparts. They operate closer to infrastructure, logistics, energy, agriculture, mobility, education and health. They build where formal systems are incomplete. That makes execution harder, but it also means successful companies can create deeper social and economic value.
The bottom line
Yellow’s undisclosed Series C is a signal that investors still see scale in African asset finance when the product solves a real access problem. Solar systems and smartphones are not separate stories. Together, they represent the household infrastructure of a more connected African economy.
The company now has to prove that it can move from one million customers toward its 10 million target while keeping affordability, repayment quality and service reliable across diverse markets. If it does, Yellow could become a reference point for how African startups turn essential assets into scalable finance products.
For Africa’s energy and technology sectors, the message is practical: the next wave of inclusion may come from companies that finance the tools people need to participate in the economy, not only from apps that sit on top of it.
