Laurent Toussaint will succeed Mr Twomey as CFO at Mason Stevens in October, moving from ASX-listed wealth management and accounting network Count Limited, where he served as chief financial and operating officer.
Prior to Count, Mr Toussaint had worked as CFO at Ambition and Dimension Data, and as associate director - mergers and acquisitions at Deloitte Australia.
Mr Toussaint will also join the Mason Stevens executive committee and “play a critical role in steering Mason Stevens through the next phase of its growth journey”.
Mason Stevens chief executive Tim Yule said: “Laurent’s strategic guidance and financial acumen, coupled with his track record of providing effective leadership, and experience in the IT and wealth sectors, made him a perfect fit for Mason Stevens.
“We’ve set our sights on ambitious growth targets and the CFO is an important part of that journey. We look forward to welcoming Laurent to Mason Stevens and benefiting from the valuable contribution he’ll make to delivering our growth strategy.”
Mr Toussaint added: “I am excited to be joining Mason Stevens at such a pivotal time of growth and momentum for the business.
“Given its impressive track record and solid potential, I am confident that together with the talented team, we will achieve great things.”
Mr Toussaint will continue in his role at Count until 29 September, which the business said would take it through the delivery of its full year financial results and ensure a “smooth transition”.
Hugh Humphrey, CEO at Count, said: “The board of Count and I would like to sincerely thank Laurent for his significant contribution to the company’s success since joining the group as CFO in 2018.
“Personally, I am very grateful for his service and outstanding support to me in my time as CEO. We wish him every success in his future endeavours.”
Mr Toussaint was promoted to the role of chief financial and operating officer in May 2022 following a tenure as interim CEO before Mr Humphrey was hired for the role.
Mr Toussaint added: “I would like to thank Hugh, the board, and the entire team at Count for the opportunity to work in the company for the last five and half years.
“Whilst the time is right for a new and different challenge, I am very proud of the role I played in Count’s success and remain a vocal advocate of the company.”
