Wagestream is on a mission to bring better financial wellbeing to frontline workers. We partner with some of the world’s most famous employers, like Burger King, Next, Asda, Co-op, Bupa and Green King to give their teams access to the UK’s leading Financial Wellbeing App through fairer financial services - all built around flexible pay. Over three million people can now choose how often they’re paid, track their shifts and earnings, start saving, use budgeting tools, get free financial coaching, and access fairer financial products. All in one financial wellbeing super-app. Wagestream is unique: VC-backed and growing at scale-up pace, but with a social conscience. Some of the world's leading financial charities and impact funds were our founding investors, and we operate on a social charter - which means every product we build has to improve financial health and reduce the $5.6bn ‘premium’ lower-income earners pay for financial services each year.
