SumUp provides debit and credit card payment processing services, both digitally and at point-of-sale. Its POS systems accept all types of card payment — chip, swipe and contactless read. Depending on the size of the client business, SumUp offers either small and affordable POS systems or models with options for custom features and add-ons.


Zilch offers its users a deferred-payment service, which it subsidizes with ad revenue generated by customer purchases. Customers can choose from options like paying over six weeks with zero fees or interest, or paying the full amount of their purchase immediately and receiving 2 percent of their expenditure back in “Zilch Rewards.” Users can then redeem these rewards on future purchases. 


FNZ makes wealth management software with solutions for asset management, financial planning, workplace retirement and other functions. Rather than manage these services in the traditional high-touch model, FNZ uses “extreme automation” to minimize repetitive tasks so users can refocus their efforts on creating more value for their clients.
