Fintech Has Evolved a Very Different ‘Core’ Technology Architecture

Fintech’s talk “Tech Stack” instead of ‘core’ systems, but what’s at the heart of fintech agility?

A Very Different Tech Evolution

Over the last decade, fintechs players have built some of the largest engaged customer bases in the digital sphere. WeBank with north of 240m customers acquired in less than 8 years, NuBank with 50m, Revolut 16m, Square’s 30m monthly active customers, Chime with 25m, Credit Karma with 10m, and so forth. They’ve all had to build tech stacks that enable a much more flexible operating model and technical capability than that of incumbent banks. For startups like Simple, Moven, Fidor and GoBank in the earliest days of the Fintech boom (2010–2012), simple capabilities like digital identity verification (replacing a wet-signature requirement) didn’t exist because banks weren’t demanding it from their core providers. Even check deposit capture wasn’t readily available as a service, and certainly elements like contactless payments, the ability to turn off a debit card temporarily, real-time receipts, transaction categorization, or P2P payment rails APIs simply didn’t exist in the way they do today.

The Emerging Ecosystem — Why it Matters?

We’re seeing a plethora of new offerings enter the retail and SME offerings space today. From BuyNowPayLater, Mobile Wallets that mimic bank accounts, SuperApps that incorporate banking, and many more experiences that won’t be supported by traditional core systems. That being said, if you wanted to support these functions or integrate them into this future world of banking, you’re going to have to think about your organization as a platform that exists in the emerging fintech ecosystem.
