What is BaaS?

More famous as Banking as a Service, BaaS is an end-to-end process, which enables the banks to carry out all financial services through an API or cloud platform.

The non-banks such as FinTech and non-FinTech businesses can connect their existing mobile and web apps to the cloud with pre-written software. The result of leveraging regulated financial infrastructure are specialized banking propositions brought to market in weeks, not months.

Beyond that, BaaS offers remunerative opportunities for everyone involved in it:

  • New propositions being enabled in the market to meet customer needs
  • Differentiating capabilities enabling market participants to win business
  • Understanding the customer buying behavior and providing customized solutions
  • Accessing the market within a short time period

What do BaaS providers do?

Providers are creating value in the BaaS ecosystem today. Normally, to acquire core elements of the baking tools, businesses reached out to the traditional banks’ distribution channels to build banking offerings in-house.

Luckily, providers expedite and simplify this daunting process by offering unique financial services propositions much faster and swifter. Essentially, they allow their partners to build financial products or services for all businesses by renting out their banking license, products, operations or technology for use. By joining capabilities and forces with other banks they compose a complete out-of-the-box BaaS solution for fintechs, start-ups and other companies.
