The era of banks and fintech companies cozying up to each other is in full bloom. Fintechs realize they can better disrupt the industry from within, while banks are looking for partners to help them navigate the digital world. Here's a look at how banks worldwide are buying, investing in and in some cases lending to fintech firms.
Groupe BPCE-Fidor Bank
The second-largest French bank acquired Fidor Bank, the popular German digital startup, last month for an undisclosed sum. François Pérol, chairman of Groupe BPCE, said the acquisition would help the bank "develop a customer-centric approach enabled by a digital banking technology and to be more involved in digital and mobile banking field."

BPCE also plans to offer Fidor's proprietary digital banking platform, which facilitates banking through application programming interfaces, as a white-label service.
