“We have used Screwloose IT as our providers of telecommunications, IT Support, and virtualisation services almost since our inception. With Screwloose’s assistance, our practice has, since 2017, been capable of fully distributed operations, with staff overseas- and in lockdowns- seamlessly integrated. Screwloose have managed our IT purchasing and security as well, designing a solution that manages both distributed work and client data security in one. Based on our experience, Alex and his team know what they are doing, are deeply responsive and take the time to understand customer needs. I highly recommend Screwloose for small and medium businesses, whether established or seeking to grow in times of change.”
