Ivy raises $20M to take open-banking payments international

Today, a startup out of Berlin called Ivy, which has built an API to create a “network of networks” for open banking payments globally, is announcing some funding in its bid to make that a reality.

Qlayers

Unique community full of inspiring, young entrepreneurs that are ready to make the world a better place. It’s simply amazing to be in contact with likeminded people that are really focused on solutions rather than problems. Self-development is the key to changing your environment and that is why I like the approach of Sigma Squared, where personal and professional development are both viewed as one.
