A new brand identity rolled out at SoftwareOne in January 2023 reflects the "all-in-one provider we have become," its CEO Dieter Schlosser claimed. The Switzerland-based software licensing and cloud services outfit has tripled in size since 2018, with global headcount now standing at 5,500. That's thanks partly to its acquisitions of arch-rival Comparex in 2019 and a string of SAP partners (including the UK's Centiq).

SoftwareONE's UK subsidiary saw revenues more than double to £356.7m in calendar 2020 as the inclusion of Comparex's sales for the first time artificially inflated its numbers. 2021 accounts were overdue as this report went to press.
