For enterprises entering or expanding across Africa, choosing where to host data has consequences that extend well beyond the monthly cloud bill. It influences who can access business information, which legal jurisdictions apply and how operations continue when access is interrupted.
At AI Expo Africa in Johannesburg which just wrapped up, we brought those questions to the stage. Stratos Lab CEO, Chris Mostert, joined ECOBLOX CEO, Doug Makishima, to present our shared vision for Africa’s sovereign AI infrastructure and the capabilities we are bringing together to support it.
Here is what we presented on data sovereignty, the death of software monopolies, and the path to a truly autonomous public stack.
Who Can Switch You Off? Why South Africa Must Own Its AI Stack
When institutions rely entirely on foreign proprietary clouds, enterprise SaaS licenses, and offshore GPU infrastructure, they don’t just rent capacity—they borrow their operational sovereignty. If geopolitical winds shift, foreign export policies tighten, or sanctions bite, access disappears overnight.
The Kill Switch Is Real
The assumption that enterprise software and cloud APIs are politically neutral utilities has been disproven time and again. History shows that when foreign governments pull the plug, technological access vanishes instantly:
- US Export Controls & AI Chips: Since 2022, top-tier NVIDIA silicon has been restricted from Chinese markets, culminating in repeated tightening even on lower-tier variants like the H20.
- Cloud & Model Lockouts: In mid-2026, compliance with US export controls led to a 19-day suspension of access to models like Claude Fable & Mythos.
- Institutional Vulnerability: In 2025, after US sanctions, an ICC prosecutor found his enterprise email account abruptly cut off, forcing a migration to Proton Mail.
- Global Precedents: From Huawei losing Google Play and Maps in 2019 to GitHub and Adobe restricting accounts in sanctioned regions, sovereign institutions routinely discover they do not own their tools.
As we highlighted on stage: If a sanction can shut down the email of an international war-crimes prosecutor, it can shut down a municipality or a critical utility.
From the Copying Wars to the “Off” Switch
For decades, technology fought over who could copy. The courts drew a clear legal boundary: copying to stay compatible, reverse engineer, or make devices with legitimate uses was fair and protected (from Sony Betamax and Sega v. Accolade to PlayStation emulators). Copying to pirate and distribute was punished (Napster, Pirate Bay).
Today, the battleground has fundamentally moved: from who can copy software to who can switch it off.
AI has permanently broken the cost barrier of software development. Take “ArtCraft”—an initiative where a single developer recreated an entire Adobe-like creative suite of 7 applications in under two weeks, with 77% of code co-written by AI. It wasn’t built by stealing proprietary code; it was rebuilt from the outside in, observing how the software behaves.
For the 90% of public sector and enterprise staff who only use 10% of standard software features, the era of paying endless foreign licensing fees for bloated, shutoff-vulnerable suites is coming to an end.
The Global Exodus to Sovereign, Open Stacks
European governments are already recognizing that technological independence is a matter of state resilience:
- France: Phasing out Teams, Zoom, and Webex by 2027 in favor of its own locally hosted platform, Visio, estimating savings of €1 million annually per 100,000 users.
- The French Gendarmerie: Operating successfully on Ubuntu Linux and LibreOffice since the late 2000s.
- Denmark & German States: Denmark’s digital ministry and regions like Schleswig-Holstein are migrating tens of thousands of accounts off Microsoft Exchange and Office toward openDesk, LibreOffice, and Nextcloud.
The cautionary tale, however, is Munich’s early LiMux experiment. Munich migrated 15,000 desktops to Linux by 2013, only to revert to Windows in 2017 because the city attempted to build and maintain the code entirely on its own. The lesson for Africa is clear: build collaboratively, not in isolation.
The Proposal: Public Money, Public Code
To protect South Africa’s critical services, Stratos Lab advocates for a simple, unified public software model:
- Build Once, Share 257 Times: Rather than every South African municipality procuring disparate proprietary licenses, a national team maintains an open stack for all 257 municipalities—and shares it with our SADC neighbors.
- Start Open, Not Cloned: Build upon proven open-source standards and public specifications rather than violating commercial licenses.
- Host at Home: Guarantee that citizens’ data and public workloads remain on African soil, hosted in local carrier-neutral facilities beyond the reach of foreign jurisdictions.
- Audit the Hardware: Enforce independent firmware and security checks on all networking and core routing kit, regardless of where it was manufactured.
A truly sovereign stack eliminates the remote kill switch across every layer: the operating system, identity management, messaging, databases, document processing, and AI inference.
Funding the Infrastructure: High-Density NVIDIA B300s
At Stratos Lab, we are building greater choice into that equation. Through our partnership with ECOBLOX and Digital Parks Africa, we are developing infrastructure that enables enterprises to run demanding AI workloads locally, with greater control over how their information is processed and managed.
Our GPU orchestration and managed AI services connect with ECOBLOX’s modular infrastructure and systems integration, supported by Digital Parks Africa’s data centre facilities.
The scale of our ambition is substantial. Together, we have announced a deployment of more than 400 NVIDIA B300 Blackwell Ultra GPUs, targeting 7.2 exaflops of peak AI computing capacity. We are building what we describe as Africa’s most powerful AI cloud, giving enterprises a local foundation for advanced model training and inference.
For our customers, that capability must translate into practical control. Where does a model process confidential information? Who can administer the environment? How can essential services recover when access is interrupted? We believe these questions belong in the infrastructure discussion from the start.
Our conversations at AI Expo Africa reinforced the importance of connecting powerful compute with the requirements of enterprises operating across the continent. We look forward to continuing those conversations and helping organisations plan their next African AI deployment.
Digital sovereignty is not about isolationism; it is about insurance. It ensures that South Africa’s critical infrastructure, municipal services, and economic data can never be disabled by decisions made thousands of miles away.
The future belongs to those who own their compute. Stratos Lab is building that foundation today.
