The fastest-growing companies list usually rewards the obvious: a slick fintech, a payments app, a logistics unicorn. It rarely rewards a company that started by helping neighbourhood shops restock soap and biscuits and ended up exporting lithium. Yet that is exactly the story of Sabi, the Lagos company that placed second on the Financial Times' 2026 ranking of Africa's Fastest-Growing Companies, published on 11 May 2026, and now the highest-ranked Nigerian firm on the entire list.
What makes Sabi worth your attention is not just the ranking. It is the radical pivot behind it, from B2B e-commerce to the traceable export of critical minerals, and what that pivot tells you about where opportunity in Nigeria is actually moving.
The pivot in one line: from soap to stones
Sabi swapped corner-shop commerce for critical-minerals export, and the numbers followed. According to the FT ranking, Sabi grew revenue from about $1.52 million in 2021 to roughly $46.5 million in 2024, absolute revenue growth of around 2,950% and a compound annual growth rate of about 213%, second only to Egyptian investing app Thndr. But the engine behind that leap is not the business Sabi is famous for. It is a new one: moving verified African minerals to global buyers.
How it started: an operating system for corner shops
Sabi began in 2020 as B2B commerce for Nigeria's informal retail. Co-founded by CEO Anu Adedoyin Adasolum and Ademola Adesina, Sabi built a platform that let the corner shops and market traders who move most of Nigeria's consumer goods restock fast-moving items, manage inventory, tap logistics and reach embedded finance. It grew fast: by mid-2023 it reported more than 300,000 merchants and around $1 billion in annualised gross merchandise value, and raised a $38 million Series B at a valuation topping $300 million. Total funding across its rounds is reported at roughly $66 million.
Why it pivoted: thin margins, a hard year, and an unexpected knock on the door
B2B e-commerce in Africa is a brutal business, and Sabi felt it. Thin margins and capital-intensive operations have humbled several once-hyped players. In June 2025, Sabi laid off roughly 20% of its workforce, about 50 people, to refocus on commodity exports. That was the painful part of the story, and it is worth remembering when you read the growth headline.
The pivot came from demand, not a whiteboard. Small-scale mineral traders, facing the same market-access problems as shop owners, started asking to use Sabi's platform to sell their products. The traceability and compliance tools Sabi had originally built for agricultural trade turned out to be exactly what mineral exports needed. "We realised that minerals were where Africa could make the biggest difference globally," Adasolum told TechCabal. "The world was changing geopolitically, and minerals were becoming central to that change."
What Sabi is now: TRACE and the minerals rail
The product is traceability, not mining. Sabi does not dig ore. It built TRACE, short for Technology Rails for African Commodity Exchange, a platform that verifies and tracks mineral shipments from mine to port using digital "passports" that log a material's origin, the labour practices behind it, and its environmental data. In markets where provenance and working conditions are under intense global scrutiny, that verification layer is the product. "Traceability is the solution," Adasolum says. "Every producer is verified, sites are audited, and every movement of material is logged."
The scale is already serious. Sabi now moves more than 20,000 metric tons of lithium, copper, tungsten and antimony every month, supplying buyers in the United States, the United Kingdom, the Netherlands, Singapore and across Asia. It says it has facilitated the movement of more than 100,000 tons of lithium out of Nigeria, ranking among the region's top five lithium-export enablers, and its platform is now live in Nigeria, DR Congo, Tanzania and Zambia. Its stated ambition is to supply about 5% of US imports in select mineral categories.
