Who we are? We're the oldest and the biggest bank in the Czech Republic. Together with other banks from Erste group we're part of one of the largest financial provider in the Central and Eastern Europe. Today I'm gonna speak from the perspective of my team which is part of the Czech bank. About our API platform and the approach to an OpenAPI. We do have around 5 million clients, over 6 hundred branches, and I don't know how many thousands of ATM's AND the reputation of a Dinosaur.
