02BUILDING

Afrevo.

Building practical technology for African businesses.

Afrevo (Afrevo Company Limited) is the Tanzanian technology company I co-founded and direct — a small studio focused on developing useful digital products designed around real operational problems that African businesses actually face every day.

One product at a time. Serving one industry well before moving to the next. Building slowly enough to build things that last.
