About Manarix
An engineering firm founded in Dakar in 2026. We help fintechs, PSPs and digital platforms build reliable payment infrastructure.
What we do
Payment integration, backend modernization and greenfield builds. We audit payment infrastructure, integrate rails and deliver production-grade platforms. No brochure sites, no staffing, no partner-account capture.
How we work
Consulting first, then retainers, then products. Two concurrent engagements. Milestone payments. Code on the client's repository from day one. Agencies and SIs keep the relationship; we hold the payment layer.
Operating model
Two engagements at a time. Zero handoffs.
In payment systems, the expensive failures come from lost context — the person who understood the constraint is rarely the person who ships the code. We cap ourselves at two engagements so that gap never opens: the engineer who maps your architecture is the one who implements it.
What this guarantees
Named senior engineers, from the first call to go-live. The person who maps your architecture writes the code, owns the deployment and answers after launch. No sales layer, no account manager, no junior assigned by default.
Where we are not the right fit
Two engagements in parallel, no more. If you need a ten-person team staffed next week, a 24/7 on-call rotation, or a vendor to answer a 200-page RFP, we are not it — and you will hear that on the first call, not three weeks in.
Commitments written into every contract
Milestone payments
You pay the next stage only after the previous one is delivered and accepted.
The code is yours
Entirely, from day one, on your own repository.
No lock-in
No dependency on a proprietary Manarix tool. Another vendor must be able to take over, and our documentation is written for that.
60-day fix warranty
After go-live, with no extra invoice.
Formally incorporated
NINEA, RCCM, service contract, compliant invoices.
