Trigold chief executive Bill Safran is standing down at the end of October to pursue other interests.
Safran has been with the mortgage sourcing system for seven years, having held a number of roles before becoming chief executive in March 2005.
Martin Colyer will be promoted to managing director and will run the firm until a new chief executive is appointed.
Chairman Peter Birch says: “I would like to take this opportunity to pay testament to the effort and success that Bill has accomplished at Trigold.
“His leadership and vision has developed the company in every conceivable way in terms of new technology, new products and new markets.”
Safran says: “I have been evaluating other opportunities – some within the mortgage industry and some not – and now is the time to seek to replicate the success of Trigold elsewhere.”
