Platform provider FNZ has appointed group chief operating officer Guy Warren as UK chief executive following the surprise departure of Paul McMahon last week.
McMahon joined FNZ to head up its UK business in October after quitting as Aegon group marketing director in May.
Last week, Money Marketing revealed McMahon has left FNZ after less than six months in the role.
FNZ says Warren has replaced McMahon with immediate effect.
An FNZ spokesman says: “FNZ confirms that Paul McMahon has decided to leave FNZ and his role as UK chief executive.
“Guy Warren, group chief operating officer, has taken on the responsibility for the FNZ UK business with immediate effect.
“We wish to thank Paul for his very positive contribution to FNZ in his time with FNZ and previously as a customer over a number of years. We look forward to continuing to work with him in some capacity in the future.”
Finance and Technology Research Centre director Ian McKenna says: “Paul McMahon is a very intelligent guy with a lot to offer the platform industry. It will be very interesting to see where he turns up next.”
