In recent years, we have witnessed a revolution in the financial technology (fintech) space. We have seen the emergence of organizations like Plaid, Bud, TrueLayer, Yappily, Yodlee, Stripe, and others, that provide financial market infrastructure. Financial market infrastructure is a critical component of today’s economy that allows businesses to easily manage financial transactions via APIs.

We have seen businesses provide banking-like services without having a banking license.
