Peeling back the banking stack, layer by layer.

This week, we've put together a special show looking at a couple of the biggest topics in fintech.

Rebank is lucky to host some of the most noteworthy figures in fintech. The perspective and insight they provide is often an indicator of where things are going.

One of the trends we've discussed on the show in the past is the move to component front, middle and backend layers to replace proprietary pieces of the financial services technology stack.

Today, we start by taking a closer look at that trend before digging into data analytics, AI and machine learning. We wrap up by looking at the potential for quantum computing to change the way we think about processing for different types of tasks.

Scott Crowder is the CTO of IBM's Quantum Computing business.

In March, IBM announced the construction of a 50-qubit quantum computer as part of its IBM Q program, an industry-first initiative to build commercially available universal quantum computing systems. IBM Q enables customers to access quantum systems and services via the cloud. The technology sits alongside classical computing solutions, like Watson, IBM's artificial intelligence engine.

IBM's progress in quantum computing mirrors advances by other institutions, all of which will no doubt contribute to quantum computing having a meaningful impact on businesses and consumers in the coming years.

Eugene is literally a rocket scientist: He led a software engineering team developing NASA-certified software for the International Space Station prior to founding Mambu.

Mambu is a cloud-based technology platform that enables banks and fintechs to rapidly address new market opportunities and reduce the high costs previously associated with software licenses, maintenance and in-house infrastructure. Mambu supports a range of customers all over the world, including OakNorth, a new UK bank we covered in Episode 12, when we sat down with their co-founder Joel Perlman. If OakNorth's early success is any indication, Mambu is a powerful platform. We've touched on core technology in a few episodes recently, which has been a conscious decision.

Even with all the coverage around fintech, it can be tough to get clear, comprehensive insight into one of the most important components of banking & fintech success: core technology.

Please enjoy today's episode with Eugene Danilkis.

Financial inclusion is a global issue. In fact, it's probably more global than most of us think. Even in developed markets like the UK, US and Western Europe, there are huge numbers of unbanked people.

Pockit, a UK-based neobank, is addressing that problem in the UK. Launched in 2014 and currently serving 123,000 customers, Pockit is making a profound impact on the lives of a huge number of financially underserved individuals.

Virraj Jatania, Founder and CEO of Pockit, joins us in Episode 21 to talk through the problem they're solving and the strategies they're employing to do so.

We get into the economics of "neobanks," non-bank fintechs that leverage third-party authorizations to offer bank-like products.

Let us know what you think on Twitter @rebankpodcast or @will_beeson.

Connect with us via Twitter, Facebook, LinkedIn or www.bankingthefuture.com to continue the conversation.

We hope you enjoy today's episode.
