There are many core banking solutions in the market targeted to different financial institutions of different sizes and different business models. Some of the popular ones on the market are Crassula, Iorys, Mambu and Temenos Transact covering needs of fintechs, neobanks and well established banks of different sizes and business models.

The world of banking is rapidly changing, as advances in technology have made it possible for consumers to access financial services in new and innovative ways. In the digital era, banks and financial institutions must adapt to stay relevant and meet the changing needs of their customers.

Core banking solution upgrades is not an easy task as it's not a computer or some gadget where you might want all the latest and greatest features available along with latest bugs. Yes, bugs are also common especially with "dot zero" versions. Core banking solution actually is a heart of your financial institution or fintech and here you need stability and minimise risks as impacts could be devastating, if something goes wrong, and thus with a system at heart of your organisation you won't play just to get "latest and greatest". You are looking stability for your heart.

Temenos Transact which until recently was known as T24 is one of the most popular and established core banking solutions around the world. In recent years it has undergone quite a few changes and got some nice improvements. Now it is cloud native and cloud agnostic, there is also Temenos Banking Cloud offering as well as Temenos has pretty much simplified integrations with other systems thanks to APIs and micro services. So... does Fintech needs such banking solution that always was mostly targeted towards banks?

My current project for almost a year is based on Serverless Google Firestore and Cloud Functions backend, and Flutter to develop Android and iOS mobile apps. That allowed me to deeply evaluate those new Serverless projects, to see all the good and bad in these technologies at this moment (year 2021).
