In an ASX statement, the firm said Donat will step down from 31 July after three years in the role.
She initially joined Clime in 2020 as the former CEO of Madison Financial Group, which was sold to licensee Infocus last month, and was appointed CEO the following year.
In a statement, Donat said: “After four fulfilling years with Clime, I have made the decision to step down as group CEO. Throughout this time, we have navigated an evolving market landscape, and I am proud of the resilience and dedication our team has shown. Together, we have achieved considerable progress in key areas.
“I want to extend my heartfelt thanks to our talented team, especially Kara Boden, COO and Tushar Kale CFO, for their exceptional contributions in reshaping the infrastructure foundations of the company. I am also grateful for the support and commitment of the extended leadership team.
“As I transition out of my role, I remain a committed shareholder and am confident in the company's potential. I wish the business continued success and thank the board, our shareholders, clients and our incredible team for their support during my tenure.”
The Clime board said it wished Donat all the best in her future endeavours but did not specify who would be filling the role once she departs.
