While most banks offer flashy apps and modern chatbots, very few can boast of truly digital cores.

The majority of banks run on outdated core systems, forced to add layer after layer on top of opaque legacy infrastructure. The outcome? A nicer-looking front-end at the cost of added complexity, heightened risk and millions in investment. It’s a heavy price to pay for relying on old systems. You’re just building future legacy technology.

While banks understand the threat, and the strategic importance of change, many struggle to address it. Yet contrary to how the industry has operated for decades, cloud technology, APIs and ecosystems allow institutions to mitigate risks, test models and implement in a controlled environment.

Time to make the switch. The 4 options.
