Jan Mohr announced he would step down as chairman over the summer. He was first appointed to the board of the then-Grafenia in March 2016.
Mohr has been replaced by former non-exec Matthias Riechert.
Another non-exec, former interim CFO Simon Barrell, steps up to become senior independent director.
Two new independent non-executive directors have joined the board: Marc Maurer who is the designated representative of Software Circle’s largest shareholder Chapters Group, where he is COO; and Brad Ormsby who is CFO of Judges Scientific and brings extensive M&A experience to the role.
Conrad Bona, the group’s longest-serving board members, steps down as non-exec after almost nine years at the business.
Software Circle CEO Gavin Cockerill thanked Mohr and Bona for their input, help and support over the years.
He quipped: “We will miss Jan's vision, notorious German directness and surprising penchant for a fish and chip supper.
“Maybe there'll be more menu options at future board get-togethers as Matthias takes on the chairman's role.
“Conrad's fair minded, well rounded approach and sartorial flair added a certain style to Board meetings that we will find difficult to replace. Of course, we look forward to seeing both Jan and Conrad regularly at future shareholder meetings.”
In an accompanying trading update Software Circle said that the performance of newly-acquired businesses was encouraging.
However, sales at graphics and design wing Nettl Systems are expected to be lower than last year, but profitability should improve.
Further M&A opportunities are being evaluated as Software Circle preps to restructure its balance sheet and redeem £6.7m of bonds.
In its most recent results to 31 March sales increased to £16.2m from £12.5m the prior year, and operating EBITDA rose from £1.3m to £2.8m.
