SalaryFinance offers businesses a financial employee benefit that allows their staff to consolidate their personal debts and repay them via a low interest, fixed-rate loan.
Ms Raffé said: “Even the most sensible spending can very quickly become unaffordable when interest rates are too high.
“This doesn’t just devastate individuals and their families, it affects their health and productivity at work too, so I’m delighted to be involved with the SalaryFinance proposition that offers such a good deal to employers and employees alike.”
SalaryFinance was launched this year by Daniel Shakhani and Asesh Sarkar.
Victoria Raffé announced she was leaving the regulator in December 2014 as part of structural changes, along with fellow executive committee members Clive Adamson and Zitah McMillan.
She has 20 years of experience as a financial services regulator but has also worked for Fidelity, Prudential and KPMG.
