Fisher resigned as a director of the business on 14 August as WealthBriefing was able to confirm by examining Companies House filings. 

WB asked UK-based Multrees, which serves wealth managers, private banks and family offices, about developments.

The business, which marked its 15th anniversary last year, didn’t elaborate on reasons for Fisher’s decision to stand down when asked about the matter.

However, in a statement emailed to this news service, Carole Lamond, chief culture and communications officer, said “Multrees is entering a new chapter under Helen’s leadership, and we are excited about the future of the business." 

“Helen brings an exceptional track record of helping financial services firms scale while strengthening their operations and client proposition, and she takes the helm at a time when Multrees has invested in its technology, data, and people. With strong demand from ambitious wealth managers for specialist, scalable infrastructure, we believe Multrees has a clear role to play in the next phase of the sector’s development.”

Multrees, which has won industry awards from WealthBriefing, serves clients such as Brompton Asset Management and Lincoln Private Investment Office, both in the UK. 

According to Companies House, active directors are David Nichol, who is chairman, while Magnus Carlsson and Elaine Clements are non-executive directors. 

In November last year, Multrees named Martyn Johnson as chief operating officer. The business reported a £1.9 million ($2.59 million) profit in 2025, its published accounts said, falling from £3.47 million a year earlier.
