Modernizing Banking with Jack Henry Platform

Modernizing Banking and Unlocking Growth with Jack Henry

Banks today face a hard truth. Customers are no longer willing to wait for better experiences.

According to recent research, 57% of U.S. banks still lack a unified customer view, reflecting persistent challenges with data silos and technology costs. In an era where customer expectations are defined by personalization and speed, this gap is not just an operational issue but a serious competitive disadvantage.

At Celsior, we understand these challenges. With our deep Jack Henry platform experience, we can help banks using Jack Henry to move faster without losing control of their core environments.

Why transformation can’t wait

U.S. banks are under pressure to deliver faster, more relevant, and more personalized services. However, many find themselves limited by legacy systems and the inability of their customers to take advantage of attractive fintech capabilities. For instance, there are more than 13,000 fintechs in the U.S. market, but fewer than 8% integrate with Jack Henry systems. It’s even worse with other popular core banking platforms.

Without strong integration, institutions remain stuck with limited digital options, slower innovation cycles, and customers who quickly look elsewhere for better experiences.

A survey found that over 70% of U.S. banks are exploring AI for customer engagement. However, only a fraction has achieved enterprise-wide adoption.

What is limiting growth today?

Limited fintech access: Limited integrations between fintechs and existing core platforms restrict customer-facing innovation.

Fragmented data: No single view of the customer across channels prevents personalized engagement.

Underused AI: Initiatives stall before delivering measurable ROI or deliver sub-optimal results given the poor, unintegrated training data

For regional and community banks, these barriers translate into slower deposit growth, fewer opportunities to differentiate, and difficulty competing with digital-first players.
