Ryan McGrath, chief executive of The Loans Engine, left the firm at the end of October as part of a restructuring of the business.
Andrew Turner, chairman and founder of The Loans Engine, said: “Ryan has made a fantastic contribution to the success of the business over the last 20 years.
“During this time he has held many key leadership positions for us, including, most recently, chief executive. Above all, his values and commitment to The Loans Engine have been exemplary.
“Whilst I am extremely sad to see Ryan leave us, we have an exceptionally experienced and dedicated team that will see us continue to deliver excellent service for our clients and mortgage partners.
“The team and I look forward to working with them closely in the coming months and I am excited to be involved once again with the business I first set up over 33 years ago.”
