We are engineers first. Connecting tools, a staff app, a mobile app, a system that stopped working. Tell us what is wrong, and we will tell you how we would fix it.
Express
Need it done today?
Small jobs at fixed prices, finished in hours by the same engineers who build the big systems.
How we work
From first call to fixed price in a day
No long proposals. No paying before you can talk to us. The person on the call is the person who would build it.
01 A free scoping call Thirty minutes on what is slowing you down. You do not need the answer - that is our job. Day 1
02 One fixed price, in writing Within a day: what we would build, how long it takes and what it costs. Big builds can be planned first in a Discovery week. Within 24h
03 Built, tested, handed over Built in stages, so something useful works early. Paid in stages, so the last payment comes after you have used it. 2 - 12 weeks
04 Watched after launch, if you want it Care keeps it running, updated and backed up. Or run it yourself - it is yours. Monthly
Planning something large? A Discovery week fixes the scope and price first. Already live and need it looked after? Care covers any system, whoever built it.
What usually goes wrong
What breaks after the work is done
These are the calls we get most. None show up while the software is being built. All of them show up once real customers arrive.
A customer sees another customer's information A customer changes one number in the web address and sees someone else's invoice. It happens more than people think, and you cannot take it back. Security
It stops working on your busiest day Month end. Payday. The week schools open. Everyone uses it at once, and it goes down - because nobody tested it with more than five people. Staying up
A customer pays and the system does not show it They say they paid. Your system says they did not. Someone checks the M-PESA statement line by line. Or the same payment is counted twice. Money
How we stop these
Every one of these happens after launch, which is what Care is for. Already built something and want it checked instead? The whole Launch Check checklist is published, so you can go through your own against it for free.
Who we build for
The sectors we know from the inside
Where we have built and still run software. Not on the list? We can still help - most problems are a payment, a record or a hand-off that stopped working.
