Howorth was chief executive of UK Employee Benefits and international chairman at JLT. He is currently chairman at ITM and a director at Smart Pensions.
Smarterly says Howorth will provide strategic input as the business expands following a recent funding round.
Smarterly supports companies with their financial wellbeing programmes and helps employees save via payroll deduction schemes, often with a contribution boost from their employer as a complement to pensions.
Howorth says: “We need more engaging propositions to turn the UK into a nation of investors. Innovation is essential.”
He adds that Smarterly’s artificial intelligence-led workplace savings platform means that employees of all ages and financial status can be supported in an engaging and cost-efficient way.
Phil Hollingdale, co-founder of Smarterly, said: “We have ambitious plans to disrupt the status quo in workplace savings and we’re building a team to take us on that journey. Duncan will be an extremely important asset to our business. We’ve known each other for many years and I’m delighted to have him work alongside me.”
