At this point Fidor Bank is a fintech dinosaur, which is actually a compliment.  Matthias Kröner, the CEO of Fidor, founded the bank in Germany back in 2009.  Many of the current concepts and themes of "Neo" and "Challenger" banks have their roots in the Fidor ethos.  Matthias has, and continues to be a true revolutionary when it comes to banking and fintech solutions.  I loved interviewing him.
