Since its launch in 2014, Smart has grown, helping tens of thousands of U.K. employers meet their auto-enrolment obligations, as well as providing workplace savings technology solutions in Dubai and the Republic of Ireland, according to a media release on Friday.

Natixis Investment Manager's equity stake forms a part of Smart’s ongoing preferred investment round and will help position the fintech for rapid international expansion as it looks to enter the U.S. and Australian markets. It follows on Smart’s recently announced strategic partnership with Link Group, one of the largest Australian Super Fund administrators.

«This investment is part of the ongoing commitment by Natixis IM to focus on the types of innovative platforms and business models that are leading change across our industry,» Jean Raby, CEO, Natixis Investment Managers, said. The asset manager joins Link Group, the leading administrator in the Australian superannuation market, Legal & General Investment Management, and J.P. Morgan as equity investors in Smart.
