Company
An engineering firm with skin in the game.
ęxaucæ is a software architecture and engineering firm founded in Dakar. We build for clients, and we build and run our own products, so we live with the consequences of every decision we recommend.
The name
exaucé
/ɛɡ.zo.se/ French, adjective
Answered, as a prayer is answered.
The name is a reminder of what the work is for: to answer a real need, reliably, for a long time.
What we value
Craft
Software is a building other people will live in. We build it to last, and to be maintained by someone else.
Stewardship
Your budget, your data and your users are entrusted to us. We treat them that way.
The long view
We plan for the fifth year of a system, not the first demonstration.

How engagements are staffed
Every engagement is led by a principal architect from start to handover. Around that lead, we assemble senior specialists in design, mobile, data and security, sized to the scope and never padded.
Principles
Low bandwidth, many languages, mixed devices. Africa first, not as an afterthought.
Built to be handed over
Everything we deliver is documented, reproducible and yours.
Conservative where it matters
Proven technology at the core. Novelty only where it earns its place.
Secure by default
Least privilege, infrastructure as code and audit trails from the first commit.
Designed for real conditions
Systems that work on the networks and devices people actually have.
Working with institutions
Ready for institutional procurement.
We work the way public bodies and international organisations need to buy: formally, in writing, and in your language.

Tell us about the system you need to build.
A short call is usually enough to know whether we are the right firm. If we are not, we will say so, and point you to someone who is.
Excellence is how we thank you for your trust. Care is how we keep it.
