AAZZUR AAZZUR
AAZZUR is a Fintech innovation that is changing banking. 10 years ago financial institutions built most of their own infrastructure, products, and services themselves. The new paradigm is to connect services. This is more flexible, cheaper, and more powerful. AAZZUR is a layer above the banks and fintech to facilitate the exchange of data,messages, and transactions. This is the promise of open banking. AAZZUR is an open banking platform that will revolutionize how data is monetized, customers are serviced, and how banks and fintech can be built. It’s a marketplace to provide the next wave of financial services. Seed / Jan 22, 2018
