Bravura Solutions chairman and director Christopher Ryan has resigned from the global supplier of wealth management applications.
Ryan was with Bravura since it started and was ready to move on now the company had progressed to a different phase, chief executive Ian Dunstan said.
"Christoper's expertise is in start-up companies and he has seen the company through to a different stage with a strong balance sheet," Dunstan said.
The board had appointed Neil Broekhuizen to act as chairman on an interim basis.
Broekhuizen is a managing partner at Ironbridge and was appointed to Bravura's board of directors last week.
His appointment and that of fellow Ironbridge director Matthew McLellan formed part of an underwriting deal between Bravura and Ironbridge that was announced in May, according to media reports.
The deal saw Ironbridge agree to the underwriting of a $33.4 million rights issues on behalf of Bravura.
As a result of the successful capital raising, Dunstan earmarked further expansion plans.
"We are cautiously optimistic," he said.
