About
Fast, friendly IT support, and the software around it.
CULLEN.TECH designs, builds and looks after the systems a business actually opens, then answers the phone when they stop.


A UK team, wherever you are working.
Twenty-two services across eight sectors: hospitality, education, professional services, retail, home offices, tourism, not-for-profit and clinics. AI and custom software sit beside the support, not instead of it.
New conversations come back within an hour during business hours. Where we run a system, the fastest critical response is one hour, on Performance. Same-day is for the phone and the remote session.
The standard, written plainly
“The till and the guest Wi-Fi have to fail separately. If they fail together, the service is the incident.”
“Attendance, the module and the staff list have to be the same fact. Three versions is not a system.”
“A leaver who can still open the file is not an edge case. It is the case.”
