✦ Built to hold
We turn bold ideas into software that is fast, secure and actually ships.
Most software in the region is built fast and patched later. We work the other way round — security, performance and clarity are decisions we make on day one, not repairs we make after a breach.
Three engineers, no account managers, no hand-offs. You talk to the people writing the code. That's why we move quickly and why nothing gets lost in translation.
✦ What we do
Everything between
the idea and the users.
-
01
Web & Product Development
Custom web applications, dashboards, portals and platforms. Built to be fast on Kenyan mobile networks, not just on our laptops.
-
02
Cybersecurity & Audits
Penetration testing, code audits and hardening. We find the holes before someone else does, then we close them and show you how.
-
03
Mobile Applications
Android and iOS apps from one codebase. Offline-first where it matters, with M-Pesa and Daraja integration done properly.
-
04
Cloud & DevOps
Deployments that don't fall over. CI/CD, monitoring, backups and infrastructure that scales when your traffic finally does.
-
05
AI & Automation
Chatbots, document processing and internal tools powered by modern AI models — wired into the systems you already run.
-
06
UI/UX & Branding
Interfaces people understand on the first try. Research, design systems and the identity that carries them.
✦ Selected work
A few things
we've shipped.
Creatify
A full penetration test and hardening pass on a SaaS platform. Fourteen findings, three critical, all closed inside two weeks.
Read more →Strategix
Offline-first delivery app for a courier fleet. Drivers keep working through dead zones; the data syncs when signal returns.
Read more →✦ How we work
Four steps.
No surprises.
- 01
Listen
A free call. You tell us the problem, we tell you honestly whether software is even the right fix.
- 02
Scope
A written plan with a fixed price and a real date. No hourly billing that quietly doubles.
- 03
Build
You see working software every week, not a status report. Change your mind early and it costs nothing.
- 04
Hand over
You own the code, the servers and the accounts. We stay on for support only if you want us to.
✦ A place for your voice
What clients say
after we've gone.
“They found a hole in our checkout that two other firms missed. Fixed it in a day and then explained it to my team so it wouldn't happen again.”
“The app works on a matatu with one bar of signal. That was the whole requirement and they're the only team who took it seriously.”
“Fixed price, fixed date, and they hit it. In this industry that alone is worth writing a review about.”
✦ The team
Three people.
You'll know all of us.
