Sandbox Réseau: make room for what’s next.

Where Africa’s founders and builders connect, collaborate, and shape the future. Builder demos, mini-talks, and open networking.

Three parts.
One evening.

Builders demo what they’re making. A few people a step ahead share short, honest talks. Then the floor opens up: trade ideas, make introductions, start something.

Questions, answered.

A gathering in Accra for Africa’s founders, builders, and curious minds. Each edition mixes builder demos, mini-talks, and open networking. Signal over noise, progress over polish.

Founders, engineers, designers, operators, and anyone curious about what’s being built across the continent. No credentials needed. Come with a question, a rough prototype, or just an open mind.

Vol. 06 takes place on 30th Oct '26 in Accra. The venue and timing are shared on the Luma page.

Request your spot on Luma. We keep the room small so conversations stay good, so it’s worth registering early.

Yes. Builder demos are the heart of every edition, and early prototypes are welcome. Share what you’re working on in the community Discord to be considered for an upcoming edition.

Our flagship pitch competition: 6–8 early-stage founders, one stage, real judges, and a live audience. It’s free to apply and free to attend. Learn more.

Join the Discord. It’s where builders in Accra and the diaspora share wins, ask for help, and keep each other accountable.
