Who we are
We are a small studio that builds software for the way Africa actually works — offline-first, mobile money native, and fast on a two-bar connection.
The long version
BrainBox237 started in 2013, writing code for shops, schools and founders who could not wait for perfect infrastructure. That pressure shaped how we build: apps that keep working when the network drops, sync cleanly when it returns, and respect a data bundle like it costs money — because here, it does.
Today the same studio ships for clients well past our borders. The discipline travels: software made to survive Douala traffic and a Buea power cut tends to feel effortless everywhere else.
How we work
One team, end to end — product thinking, design, mobile, web and the cloud underneath it. No hand-offs to three vendors, no guessing who owns the bug. We write production code, not slideware, and we own what we ship after launch.
We are deliberate about quality: typed codebases, real test passes, signed releases, and reviews against the policies of the stores we publish to. Boring rigour, so the product can be exciting.

Flagship product
Stocka
Know your stock. Know your money.
Stocka is our offline-first inventory and point-of-sale app for African retailers and SMEs. Track stock, record sales and debts, manage expenses and watch your margins — all on the phone in your pocket, with or without internet. When you reconnect, everything syncs to a secure cloud and your devices stay licensed even offline.
Where we are from
From the foot of Mount Fako to the ports of Douala — we build here, on purpose.
Being a Cameroonian studio is not a footnote on our site; it is the reason our software is good. We test on the phones people actually carry, on the networks they actually have, paying with the money they actually use. That is a hard place to build — and exactly why what we ship holds up anywhere.
