About
We build for the people software usually forgets.
Sentrio Systems is a South African software company. Our users work on their feet: at gates, on sites, in vehicles, on night shift. We build tools that respect that.
Why we exist
Good software reached the office years ago. It rarely reached the gate.
A guarding company can run a hundred posts on paper occurrence books, WhatsApp check-ins and a month-end spreadsheet. It works, until someone asks for proof.
We started Sentrio Systems to build the tools those companies should have had all along: simple enough for a first-time smartphone user, strict enough to stand as a record, and priced for a business that counts every rand.
Our first product, Truepost, was built with a working security company as its first customer. Its owners set it up themselves, and where they could not follow a screen, we rewrote the screen.
"Software for the people"
It is our slogan and our test. Before anything ships we ask whether the person at the gate, the driver in the vehicle and the owner at the desk can each use it without being taught.
How we build
Four rules we do not break
It works where the work is
On a gate, in a basement, on a farm. Our software saves first and sends later, because bad signal is normal there.
It runs on the phone people own
We test on entry-level Android phones. If it is slow there, it is not finished.
It says things plainly
Ordinary words, big buttons, one thing at a time. A screen should need no training.
It is honest with people
The person on the phone knows what is recorded about them and why. Records cannot be quietly changed.
The person behind it
Luhan Strydom
Founder and director of Sentrio Systems.
Luhan founded Sentrio Systems in 2026 and leads its product and its engineering. Truepost was built alongside a working guarding company, and Luhan still sits with the people who use it when something on a screen is not clear.
A message to [email protected] reaches Luhan directly.
You deal with the builder
No call centre and no ticket queue between you and the person who can change the software. That is the advantage of a small company, and we intend to keep it as we grow.
