Grayon designs, builds, and deploys production-ready web and mobile products for founders and teams — end to end, one team, no handoffs. If it needs to work the first time, this is who you call.
Built the systems behind MyArmyApp (personal safety, live in production), the hospital management platform running Kam Industries’ operations, and Luuprs — our own SaaS product that turns meeting commitments into follow-through.
Every line of code is written to go live — tested, deployed, and monitored. No “we'll fix it after the pitch.”
Web, mobile, and backend, handled by the same team from day one. No agency handoffs, no lost context, no re-explaining your product to a new contractor every sprint.
Architecture decisions are made for the business you're building toward — not just the MVP in front of you. Fewer rewrites later.
Fixed scope, a real timeline, and one invoice you saw coming. No change-order surprises three weeks in.
From first line of code to App Store approval, Grayon covers the full lifecycle of a product.
Cross-platform iOS and Android apps built with React Native and Expo — from first prototype to App Store launch.

Most founders don’t lose momentum because the idea was wrong. They lose it waiting — for a freelancer to reply, for a dev shop to finish someone else’s project first, for a demo that almost works to become a product that actually does.
Grayon exists for the gap between “I have a plan” and “it’s live.” We’ve built a personal-safety app that people trust with their location in an emergency, a hospital system that clinical staff use every day to manage real patients, and Luuprs — our own SaaS product, built the same way we build for clients, because we hold our own work to the same standard we hold theirs. Those aren’t forgiving categories to get wrong — which is exactly why they’re the proof this works.
You bring the vision. We bring the build, the architecture, and the discipline to ship it once, correctly.
One-tap SOS, live location, and encrypted evidence capture — trusted with people's safety in real emergencies.
Runs daily clinical and administrative operations for Kam Industries — a category with no room for a system that's “almost” right.
Turns meeting commitments into follow-through — built the same way we build for clients, to the same standard.
We deliver solutions with the best web and mobile technologies.
1 / 6A personal safety and emergency response app: one-tap SOS alerts, live location sharing with trusted contacts, AI-assisted incident monitoring, and encrypted evidence capture.
Result: Shipped to both app stores with a structured QA pass before launch.
1 / 8The marketing site for MyArmy, built to explain the app's safety features to individuals, families, schools, businesses, and security agencies — covering how it works, pricing, and FAQs, and driving app downloads.
Result: Launched alongside the app to support its store listing and lead generation.
A freelancer gives you one person's bandwidth and no backup. A large agency gives you an account manager between you and the people actually building. Grayon gives you a small, direct team that designs, builds, and ships — full stack, no middleman.
Scope conversations happen before a line of code is written, and any changes mid-build are scoped and priced up front — never billed as a surprise. You'll always know what a change costs before you say yes to it.
Depends on the product, but most MVPs move from kickoff to a live, testable version in weeks, not months. You'll get a real timeline in the first conversation, not a vague estimate.
No. Every build includes a post-launch support window, and ongoing maintenance or feature work is available on a straightforward monthly arrangement — the same team that built it, not a handoff to someone new.
Yes. Every build goes through our internal QA process first, then we handle App Store Connect and Google Play Console submission, compliance checks, and any back-and-forth with app review teams.
Grayon Technologies is a CAC-registered Nigerian company, so we can contract and invoice formally. We're based in Lagos and work with startups and businesses across Nigeria and beyond.
