Critical Software

At Critical Software, we embody transformation. Our teams are experts in engineering change, helping to build a better and safer world through trusted and groundbreaking technologies.

Over the last 25 years, we’ve helped major players in financial services embrace a digital future. From core banking modernisation to data engineering and everything in between, we’ve been integral to upscaling start-up challenger banks and upgrading established financial institutions.

As a bespoke software provider, digital transformation comes naturally to us. We specialise in optimising through our Build Operate Transfer model. Guided by you, we build the system, show your people how to manage it, and then transfer ownership. By uniting business priorities, people and technology, we help to create the landscape needed for successful adoption across your institution.

Our company culture shapes the way we work. Because our people sit at the heart of everything we do, we know what it takes to bring people on board during periods of business transformation. This means changes to processes and systems are done the right way: by putting people first.
