Mr Vasilieff led the sale of Novia recently to private equity firm AnaCap Financial Partners.

At the time of its sale Novia had assets of £9bn on the platform.

Mr Vasilieff also led the Novia team in building a retail and institutional platform for Aegon, as well as launching a multi-currency offshore platform Novia Global, where he remains as chairman. 

Prior to Novia, he was one of the founders of the Old Mutual platform Selestia, one of the earliest platforms which was et up in 2001. He also has extensive institutional asset management experience and was a member of the M&G executive team prior to his platform career. 

He said: “I am absolutely delighted to be joining such a successful and rapidly expanding business.  Having spent over 20 years in the UK platform space I believe the Multrees proposition, with its customisable, modular approach, is the next step in the evolution of platforms. Multrees is superbly placed to meet these changing requirements and I am very much looking forward to working with Chris and the team to drive this to market.”

Multrees CEO Chris Fisher said: “Bill has an unbridled wealth of knowledge in the UK and international platform space and his experience and creativity will be a huge asset to our expanding business.  Multrees is going through a period of significant growth and development and Bill’s in depth understanding of both the UK wealth management and platform market as well as his background in asset management will be of huge benefit as we continue to grow.”

Multrees provides outsourced investment services to wealth managers, private banks, family offices and advisory businesses.
