South African start-up Stratos Lab has begun deploying what it and its partners say will be the most powerful AI cloud on the continent, built on Nvidia’s latest shipping B300 “Blackwell Ultra” GPUs and hosted at a data centre in Centurion, north of Johannesburg. The stack will be up within three months.

Announced on Wednesday at the Activate AI conference in Cape Town, the venture pairs Stratos Lab as cloud operator, Dubai-based integrator Ecoblox and carrier-neutral operator Digital Parks Africa (DPA) as initial host. Taiwan’s Giga Computing, a Gigabyte company, is supplying the servers.
