Tim Cook is stepping down as Apple's chief executive after 15 years at the helm, leaving behind a company valued at $4.5 trillion — a figure that makes Apple larger than the combined GDP of every sub-Saharan African economy. According to Business Insider Africa, that growth rested in significant part on African raw materials — cobalt from the Democratic Republic of Congo, lithium from Zimbabwe, and platinum-group metals from South Africa — yet Apple's direct investment and philanthropic footprint on the continent remained negligible throughout Cook's tenure.

Cook took over from Steve Jobs in August 2011 when Apple's market capitalisation stood at roughly $350 billion. The 13-fold increase to $4.5 trillion came on the back of a supply chain Cook himself architected, one that depends on African mineral extraction at the base while concentrating all the high-margin design, software, and services revenue in Cupertino, Ireland, and a handful of Asian manufacturing hubs. Africa supplied the inputs; Africa did not share the upside.

The incoming CEO — whose identity Business Insider Africa describes as facing an immediate strategic test — inherits a company wrestling with slowing iPhone upgrade cycles, intensifying regulatory scrutiny of the App Store in the EU and UK, and a generative-AI race it entered later than rivals Google and Microsoft. How the new leadership responds to those pressures will shape whether Apple deepens or diversifies its African supply relationships, and whether it makes any serious move into Africa's 1.4 billion-person consumer market.

Cook's legacy on the continent is instructive precisely because of its omissions. He built the most profitable consumer hardware ecosystem in history without opening a single Apple Store in Africa, without a meaningful developer fund targeting African engineers, and without a manufacturing or assembly partnership anywhere on the continent. African governments and mining companies that hoped a post-Jobs Apple might direct some of its cash pile — which at points exceeded $200 billion — toward local beneficiation or skills programmes were disappointed.

The same week Cook's exit was confirmed, Uber announced it is cutting 10% of its global workforce as CEO Dara Khosrowshahi moves to flatten management layers, according to a separate Business Insider Africa report citing Khosrowshahi's internal memo. For African operations, Uber's footprint spans at least a dozen cities across South Africa, Nigeria, Kenya, Egypt, and Ghana, and the company has previously described sub-Saharan Africa as one of its faster-growing ride-hail corridors. A 10% global headcount reduction that targets middle management could mean thinner regional teams on the continent, slower localisation decisions, and reduced responsiveness to the hyperlocal dynamics — cash payments, motorcycle taxis, two-wheeler logistics — that determine market share in African cities.

Uber's African rivals, including Bolt, which is headquartered in Tallinn but derives a substantial share of its volume from African markets, and homegrown players like inDrive and Little Cab, will be watching closely. Any reduction in Uber's local sales, government-relations, or driver-support capacity creates an opening. The timing also matters: Uber Eats and Uber Freight are both scaling in select African markets, and a leaner management structure could slow those efforts just as last-mile logistics investment is accelerating across the continent.

Together, the two stories point to a structural tension that African policymakers and startup founders should take seriously. Global tech giants treat Africa as an input economy — mineral supplier, ride-hail growth market, app-download base — rather than as a site of R&D, manufacturing, or senior decision-making. Cook built $4.5 trillion in value from African cobalt without building a single factory or developer campus on African soil; Khosrowshahi is now cutting the very management layers that might have championed deeper local investment.

Why it matters: Africa's leverage in these relationships is growing — DRC holds roughly 70% of the world's cobalt reserves, and several governments are pushing hard for processing to happen onshore — but that leverage only converts into economic value if African negotiators demand it explicitly and back the demand with credible export or processing restrictions. The leadership transitions at both Apple and Uber are moments of institutional reset; they are precisely the windows in which new terms can be set.
