What we do
Everything you need to take a product from idea to revenue
Design, engineering, launch and growth under one roof — so nothing falls between agencies.
Why KopixX
Anyone can write code. Very few have shipped and scaled their own product.
That difference is the whole reason clients choose us — and it shows up in the questions we ask before we quote.
We've made money from our own products
Most agencies have never had to keep a product alive after the invoice cleared. Ours are live on the Play Store earning revenue today. That changes every decision we make on your build.
Money-grade engineering
Double-entry ledgers, idempotent transactions, audit trails, encryption and fraud rules. If your product touches payments, that discipline is not optional.
Shipped, not perpetually 'almost ready'
Two-week sprints, a working build at the end of every one. No six-week silences, no launch dates that quietly slip.
Global clients, Nigerian roots
We build for founders in Lagos, Port Harcourt, London and Toronto. Local context when you need it, international standards throughout.
Selected work
Real products, in real app stores, used by real people
From gift card trading and multi-currency wallets to ride-hailing and heavy-industry storefronts — here's what we've shipped.

Meet the founder
“We don't just know how to build — we know how to monetize, scale and grow.”
We've been in this field for over seven years, and in that time we've helped clients globally create and launch numerous mobile and web applications — crypto, fintech, VTU, ride-hailing, logistics and custom AI applications with AI-driven solutions.
We don't just build projects. We build products that actually work in the real world and solve problems. But most importantly, our own apps over the years have grown to over a million downloads collectively on the Play Store and earned millions of naira in revenue — so we don't just know how to build, we also know how to monetize, scale and grow your product.
When you hire us, we bring all of that into your project.
- Operator, not just engineerOur own apps have passed a million downloads collectively and generated millions of naira. We know what happens after launch.
- Built for real conditionsNigerian network reality, payment failures, Play Store policy, fraud attempts — we've handled all of it in production.
- Partner, not vendorWe'll push back on features that won't earn their keep. You're paying us to be right, not agreeable.
How we work
A process built for certainty, not surprises
You always know what's being built, what it costs, and when it lands.
- 01
Discovery & strategy
We interrogate the business problem before the feature list. You leave with a scoped plan, a fixed quote and a timeline — free, no obligation.
- 02
Design & prototype
User flows, then high-fidelity screens, then a clickable prototype you can put in front of real users before we write production code.
- 03
Engineering sprints
Two-week sprints with a working build at the end of each one. You see progress continuously — no six-week silences.
- 04
Launch & store submission
We handle deployment, Play Store and App Store submission, listing copy, ASO keywords and data safety declarations.
- 05
Growth & scale
Post-launch we instrument the funnel, tune monetization and scale infrastructure as your user base grows.

Client words
Founders keep coming back for the same reason: the thing actually works
A selection of feedback from the teams whose products we've designed, engineered and launched.
“They didn't just deliver an app, they questioned our business model until the product made sense. We launched on Play Store in ten weeks and the payout flow has been rock solid since day one.”
“The wallet handles USD and EUR accounts, virtual cards and bill payments without a single reconciliation issue. That level of care with money is rare.”
“Our enquiries went from a trickle to a steady stream of qualified quote requests. The site is fast, it ranks, and the WhatsApp funnel converts.”
“What set KopixX apart is that they've actually run products of their own. The advice on monetization and store listing was worth as much as the build.”

Questions
Straight answers to the things clients ask first
Everything founders ask before working with KopixX. Anything else — just ask.
What does KopixX Software Interactive Services do?
KopixX is a Nigerian software company that designs and builds web applications, mobile apps and custom AI solutions. We specialise in fintech, crypto, VTU, ride-hailing and logistics products, and we also help founders monetize and scale what they launch.
Where is KopixX located and do you work with international clients?
We are based in Port Harcourt, Rivers State, Nigeria, and we work with clients across Nigeria and globally — including the UK, US and Canada. All collaboration is remote-friendly with clear reporting rhythms.
How experienced is the team?
Over seven years building and launching digital products. Our own applications have collectively passed a million downloads on the Google Play Store and generated millions of naira in revenue, so we bring operator experience as well as engineering skill.
How much does it cost to build an app or website with KopixX?
Websites generally start from ₦450,000, mobile app MVPs from around ₦2.5M, and full fintech platforms are scoped individually. Every project gets a fixed, itemised quote after a free discovery call — no open meters.
How long does a project take?
Marketing websites take 2–4 weeks, mobile app MVPs 6–10 weeks, and larger platforms 3–5 months. You receive a working build every two weeks throughout.
Do you provide support after launch?
Yes. Every project includes 90 days of post-launch support, and most clients continue on a maintenance or growth retainer covering monitoring, updates, new features and store management.
Who owns the code and intellectual property?
You do — completely. Source code, designs, accounts and infrastructure are transferred to you on final delivery.
