Africa's AI. Powered from the Space.
The world's first stratospheric AI infrastructure. Balloon platforms at 20km altitude. AI from above the clouds.

What we built
We put the AI in space.
Not cloud. Not a metaphor. Literally.
The insight
The problem
GPU farms weigh 35kg per unit.
Draw 6,000 watts each.
They cannot fly.
The insight
Inference chips weigh under 1kg.
Run on 5 to 50 watts.
They can.
Train the models on the ground. Fly the inference chips into the stratosphere. That is what Kasi is built on.
Latency
20x
Faster.
Kasi platforms deliver 5 to 15ms latency across Africa. Today, users wait 150 to 300ms for every response. Ten to twenty times faster, from space.
Energy cost
Zero.
Every Kasi platform runs entirely on solar power. No electricity bill. No grid dependency. The sun powers the AI. Forever.
Reach

Africans served.
Three platforms. Three gateway cities. Fifteen countries. 1.5 million square kilometres of coverage.
Ground infrastructure
Three gateways.
One continent.

The roadmap
From stratosphere to permanent orbit.
Phase 01
Stratospheric
2027 to 2029
Hybrid balloon platforms at 20km altitude. Ground gateways in Abuja, Nairobi, and Kigali. 500M+ Africans served with sub-20ms AI.
Phase 02
Low Earth Orbit
2030+
Satellite deployment at 400 to 600km altitude. Permanent orbital infrastructure. No balloon replacement required.
Phase 03
Geostationary
2032+
36,000km orbit. A permanent African orbital data center in the sky. The final form of what we are building.
“They can shut down a server.
They cannot shut down the sky.
That is where we built.”
