Founded by chairman Alexander MacAngus, 59, and chief executive Richard Smith, 44, in 2010, this Surrey company spent four years on development before debuting its payment processing platform for online retailers. It also helps clients increase their credit card acceptance rates worldwide, reducing so-called “basket abandonment”. It raised £10m from private equity firm Magenta Partners in 2017. Profits rose to £3.6m last year, with businesses in Canada, Australia and Nigeria now using its platform.
