Who We Work With














Stem Systems systematically onboarded each of our eight sites and integrated them seamlessly. Remarkably, there was no downtime reported from any of the plants, and numerous long-standing support issues were also resolved during the process. We required dependable support during these projects and for the long term, and Stem Systems exceeded our expectations. I would highly recommend Stephen and his team to anyone.
David McKee,
CTO
We had an aging VMware server estate and growing IT support needs, with multiple offices and remote workers across Ireland. In 6 weeks Stem migrated our SAP ERP software, company file shares and apps to Azure, allowing us to empty our server cabinet. Now, I manage our laptops with Intune and we access our programs anywhere without a VPN.
Brian Aston, IT & Operations Manager,
Laydex Ireland
MMW are going through an exciting period of growth and it's great to have the technology to underpin this and grow with us. We are serving an ever-increasing client base and Azure gives us the confidence that we can be available for them.
