Chamberlain, who launched the wealth planner acquisition business in 2009, died earlier today with no further details given by the firm at the time of writing.
A brief statement said: “Succession is sad to announce the sudden death of its founder and group CEO, Simon Chamberlain, who died earlier today.
“Our thoughts and concerns are with his wife Helen and children Charlotte, Henry and Olivia at this difficult time.
“No further announcements are being made.”
The existing management team will continue to run the business, headed by chairman Ray Pierce.
With over £200m ($246m, €229m) in funds under management, Succession last year secured £25m from HSBC and existing shareholders to target the “best 50 firms from its affiliated membership” by the end of 2017.
Just two weeks ago it acquired IFA Chambers Group and financial planner Plan4Wealth for a total of £10m, with female-focused adviser Independent Women joining the ranks just days later, marking International Women’s Day.
Chamberlain was a founding partner of St James’s Place Capital – ranked number one partner in 1993 and 1995 before moving to Zurich UK as development and recruitment director between 1999 and 2003.
He moved to Zurich UK as development and recruitment director between 1999 and 2003 before launching national IFA business Thinc Group in 2003 – now Bluefin – where he served as chief executive until 2007.
