In the latest episode of the What the FinTech? podcast, we’re joined by Dirk Marzluf, Chief Operating and Technology Officer at Banco Santander, to learn more about the development and deployment of the bank’s self-built core banking solution Gravity. Dirk and FinTech Futures editor Paul Hindle cover how the project came about, how the bank has gone about building Gravity and the steps involved in getting this project completed, the challenges involved in migrating to a new core, and the key benefits for both customers and the bank in having its own in-house core platform powering its operations. And finally, we find out what fintech buzzword Dirk wants to cast into our Fintech Jail!
