Mr Gale, who can boast a career in financial services that spans three decades, replaces Rupert Pennant-Rea, who served as chairman of Defaqto for more than six years.
He said: “I very much look forward to working with the team to achieve our strategic goals. The RDR and the evolving regulatory landscape play to Defaqto’s core strengths and present many new opportunities for us to deepen our relationships with our clients.”
Zahid Bilgrami, Defaqto’s chief executive, said: “Patrick is a highly respected financial services practitioner with technology experience. As a financial research and software company, Patrick’s experience and knowledge in these areas will be incredibly valuable.”
Mr Gale was previously chief executive of Sesame and, more recently, executive chairman of Positive Solutions and Origen. He also served in senior roles in the past for Misys plc, HBoS, Aegon and Just Retirement.
