"It has to touch the lives of people": the Gates Foundation's challenge to Africa's AI builders

Africa’s artificial intelligence developers should measure success by improvements in healthcare, education and incomes rather than the number of products they launch, the Gates Foundation’s Nigeria director told Moonshot by TechCabal in Lagos.

Uche Amaonwu said AI could widen access to knowledge, services and economic opportunity, but warned that its benefits would depend on deliberate choices about how the technology was developed, financed and deployed.

“For a technology to really be impactful, it has to touch the lives of people,” he said during a keynote address.

His remarks set out a challenge for developers and investors seeking applications for AI across the continent: moving promising tools beyond trials and into the institutions and communities expected to use them.

Amaonwu pointed to the foundation’s Goalkeepers report on AI and equity, released around the UN General Assembly, describing its message as “exciting, but also cautionary”. AI could become “a powerful equaliser”, he said, but that outcome was far from assured.

“If we are not deliberate about how AI is developed and deployed, we could end up widening the very inequalities that we’re actually trying to close.”

The foundation’s approach, he said, starts with three objectives: preventing avoidable maternal and child deaths, protecting the next generation from deadly infectious diseases, and helping hundreds of millions of people escape poverty.

These were “human condition goals”, he said. AI’s value would lie in whether it accelerated progress towards them.

A central part of that effort is the Nigeria AI Scaling Hub, hosted by Lagos Business School in partnership with the Federal Ministry of Communications, Innovation and Digital Economy. Backed by up to $7.5mn from the foundation over three years, the hub aims to expand the use of proven AI tools in health, agriculture and education.

Its focus is the difficult transition from a successful pilot to sustained adoption. A tool that works in a trial still needs infrastructure, institutional support and a viable funding model before it can reach people consistently.

Amaonwu identified four requirements for making that transition.

Developers needed shared infrastructure, including connectivity, trusted data, and systems capable of exchanging information, so that each company did not have to build the same foundations independently.

Tools also needed to reflect Nigerian conditions and languages, earn users’ trust from the outset, and have a clear route to adoption and payment. Identifying who would use a product — and who would finance its continued use — was as important as developing it.

The argument places responsibility beyond technology companies. Governments shape the conditions for adoption through regulation and public systems, while investors determine which businesses receive the capital to expand.

Amaonwu urged the Moonshot audience to return the following year with evidence of practical results like clinics where patients had received care, classrooms where children had caught up, and farmers who had secured better prices for their harvests.

“No one in this room can do all of this alone,” he said. The future worth building was “the one that we must build together”.

Obiex says Nigeria’s stablecoin market is far more efficient than it was in 2018 and 2019, when the gap between buying and selling a dollar of crypto in naira ran as wide as ₦20 to ₦30. Demand has scaled since, but the supply behind it is still spread across many small sellers.

That’s the current state of Nigeria’s stablecoin market, according to Temitayo Sadique, managing director of Obiex Business, the business arm of Nigerian crypto exchange Obiex.

“Because of the exceptional need for stablecoins from cross-border trade and remittances, and crypto exchanges cropping up every day, we’ve seen demand scale,” Sadique said at Moonshot by TechCabal. “But supply, on the other hand, has remained scattered.”

Sadique said $19 billion in stablecoins came into Nigeria in 2025. The country has taken about 60% of sub-Saharan Africa’s stablecoin inflows since 2019, according to a June report by the International Monetary Fund.

Scattered supply makes that volume expensive to move. A company filling a $1 million order might deal with 10 peer-to-peer (P2P) traders, Sadique said, each selling a slice at a slightly higher rate: ₦1,400 per dollar, then ₦1,402, then ₦1,403. By the end, its average price is worse than the first quote. As volumes grow, he argued, platforms that can fill large orders at one price will set the terms for everyone else.

Obiex has built its business on that bet. It began in 2016 as Paylot, a crypto payment gateway, before shifting to converting crypto into naira when it saw that was what users wanted. It has never raised venture funding.

Sadique said 105,000 merchants in Nigeria, Ghana and Cameroon now trade on Obiex, alongside more than 100 businesses, from exchanges and remittance companies to fintechs. By his count, $1 of every $10 in stablecoins that moved through Nigeria last year went through Obiex.

For Sadique, liquidity means delivering money on time. Promising someone $100 next week means little if the money isn’t there when the week comes, he said. “It’s kind of like a supply-chain question, where you’re answering: can I fulfil this obligation now, when the customer needs it?” Obiex’s answer includes credit that lets clients take liquidity today and settle tomorrow, and price locks while crypto deposits are still confirming.

For large trades, Obiex offers a quote system that fixes the rate on orders of $1 million to $10 million. “We don’t just give you an average price to execute your transaction; we give you a quote and lock in that price for you,” Sadique said.

Regulation is already pushing the market toward bigger players. Since January, Nigeria’s Securities and Exchange Commission has required crypto exchanges and custodians to hold ₦2 billion in minimum capital, up from ₦500 million, a bar many smaller platforms will struggle to clear.

In Sadique’s view, an efficient stablecoin market is one where a $1 million order clears at a single price, and that depends on who can supply liquidity when it is needed.
