Who we are

We build Nigerian technology that works on the first Monday of every month.

AandA is a technology company registered in Nigeria under CAC Business Name 2511781, with a UK arm at AandA Labs Limited (Companies House 872002). We deliver software, AI, data analysis, mobile, web and hardware engagements to institutional clients across Nigeria and the United Kingdom.

Every project is delivered by our in-house engineering team. We do not sub-contract our core work. The systems we ship for you are systems we would run for ourselves — and in the case of our AandA Smart BI platform, systems we already do.

The measure of the work isn’t the launch. It’s the first Monday of every month, when your team logs in and finds the system still doing the job. That’s the discipline we bring.

In-house team

“Every line of code we ship is written by someone whose name we know.”

Services

Eight registered service lines.
All under one CAC certificate.

We deliver each of the following under our registered scope. Every engagement is scoped, quoted and led by a named principal.

Software Development

Custom Django and Python systems built for Nigerian businesses.

We design and build production software that solves real business problems — from custom ERPs and back-office systems to public-facing customer portals. Our own AandA Smart BI platform, built end-to-end in-house, runs 21 integrated modules and 25+ automated workflows in daily production.

Web Development

Fast, secure, mobile-first websites and web applications.

AI + Machine Learning

Practical AI that solves real problems, not hype.

Data Analysis

Turn scattered business data into decisions you can act on.

Mobile App Development

Native-quality mobile experiences for iOS and Android.

UI / UX Design

Interfaces users understand at first glance.

We design digital products the way we run our own business — starting with the user, iterating fast, and treating clarity as a feature. Our design system underpins every AandA product and dashboard, from the shop-floor cashier screen to the CEO's remote command interface.

Product design for web … Design systems and component … Landing page and marketing … Dashboard and admin interface … Design reviews and usability …

Hardware Engineering

How we work

An engagement is a conversation, then a system.

Scope

Understand before we quote

We spend the first week understanding the outcome you need before we quote. No engagement starts before we understand what “successful” looks like to you.

Build

Two-week sprints, running software

We work in two-week increments. You see something running at the end of every second Friday. If it isn’t right, we correct in the next two weeks.

Run

Handover, not hand-off

When your system launches we don’t disappear. Every engagement includes a defined operations plan, on-call arrangement, and documented handover to your team.
