Introduction

For digital-first banks, building a seamless product experience is just the beginning. The real challenge comes next, when you have to secure your platform against digital crime every day to maintain your customers’ trust – a currency more valuable than capital itself. 

The founders of German neobank N26 know this better than most. They also knew that to scale a fully mobile finance platform across Europe, they would need to address the security concerns of potential customers, adhere to the increasingly complex compliance requirements of multiple countries, and stave off the rising threat of financial crime.  

Easy, right? 

No, but possible — with the right partner.
