Blythe Masters, group CEO of FNZ is to leave the platform engine after just two years at the helm.
She will remain with the firm for six months to help ensure an orderly transition, during which period executive group chair Stephen Welch will become interim CEO while a permanent replacement is found.
The platform said her exit will not see any changes made to its planned transformation programme.
Mr Welch said: “I look forward to working closely with colleagues across the Group as we continue to execute our transformation programme, improve delivery for clients and build on the significant progress already made.
“On behalf of the board, I would also like to thank Blythe for her leadership and significant contribution to FNZ. FNZ enters this next chapter as a stronger and more focused organisation, and I am confident in the opportunities ahead for the business, our clients, our shareholders and our people.”
Before joining FNZ, previous roles for Ms Blythe included CEO of blockchain fintech Digital Asset Holdings and 30 years at J.P.Morgan.
The FNZ platform engine has been undergoing a transformation and refocus programme following a challenging period.
FNZ has come under considerable scrutiny from advisers and platforms over the past year following concerns over financial stability, with the firm admitting its costs had risen by 55% over the past five years, and concerns around the number of UK adviser platforms reliant on its technology.
The global platform engine posted a $1.4bn (£1bn) loss in 2025. It has also seen changes to more than a third of its board over the past year.
In August the platform engine agreed to sell its German banking arm FNZ Bank to Advent as part of a restructure to focus on its core wealth management technology business.
The deal, for an undisclosed sum, is expected to be completed in the second half of 2027, subject to approvals.
Last August FNZ launched a generative AI tool known as FNZ Advisor AI, which it claimed should help advisers enhance productivity, deliver a more personalised advice and serve more clients at scale.
In July 2025 it announced a five-year global strategic partnership between FNZ and Microsoft, aimed at accelerating digital transformation in the wealth management industry and enhancing FNZ’s AI, automation and cloud capabilities worldwide.
Last year FNZ also raised £495m from existing institutional shareholders to support its long-term business plan.
It also FNZ also announced the conclusion of a Section 166 review and associated Voluntary Requirement (VREQ) in the UK. This followed the company’s strengthening of its governance, delivery, risk management and operational frameworks, FNZ said.
FNZ claims to have more than 650 financial institution partners, more than 30m end investors and £2.4trn (£1.8trn) in assets on its platform.
The business was founded in New Zealand in 2003 and has more than 7,000 employees globally based in more than 30 locations across the world.
The platform technology provider said the deal supports its long-term growth ambitions by ‘reinforcing its positioning as a technology platform provider for wealth businesses globally’, including in Germany where FNZ Bank will remain a client under the terms of the deal.
