The merger between mPOS innovators SumUp and payleven announced this week will create a new giant in the industry that processes more than €1 billion a year in 15 countries.

Founder and CEO of SumUp Daniel Klein called the deal a “game-changer for the mobile payments industry” and a major move toward his vision of building the “first ever global card acceptance brand.” payleven co-founder Konstantin Wolff referred to SumUP and payleven as “two complimentary teams sharing the same vision” and said the merger would produce a company that is “larger and more powerful than the sum of its parts.” The combined entity will operate as SumUp.
