Who builds it
Daniel Clement Masubi
Founder & Data Engineer
Daniel Clement Masubi is a Tanzanian data engineer. He has built reporting and analytics platforms in production for financial services, automated market-data pipelines that run unattended every month, and multi-agency early-warning tooling with map generation, role-based access and automatic document delivery. He works on embedded systems — microcontrollers, single-board computers — as groundwork for flight hardware. He founded Interstellar Solutions to give that work a direction.
How we work
Evidence over hype
We say what was built, what it does, and what it does not do.
Earth first
The nearest use of space is looking back at the ground. That is where we start.
Institutions, not apps
We build for the agencies, universities and programmes that outlast any single project.
Open by default
Interstellar Challenge is where we invite the public in without lowering the standard.
Dealing with us means dealing with the engineer who builds the system — in your time zone, and answerable for it afterwards.
The mission
In 2026 Tanzania published a five-year strategic plan for space programmes — From Mount Kilimanjaro, the Peak of Africa, to Space — and its universities are building TanSat-1, the country's first CubeSat, for deployment from the International Space Station under the UN and Japan's KiboCUBE programme. Interstellar Solutions exists to make those steps count: a satellite is only as useful as what happens to its data once it reaches the ground.
