The challenge

Marginalen Bank needed a new eBanking platform that would enable it to grow its business and extend services over the long term. A seamless migration was required for both private and corporate customers, as was the flexibility to add new functionality for future services such as mobile banking lending. What’s more, the transition had to be completed in less than a year.

It was critical to find a partner with the business understanding and in-house technical competence required to ensure a smooth implementation. Three things set Crosskey apart: its proven platform, its track record of success and its outstanding level of commitment.

We needed a trusted supplier we could grow with over time. That’s Crosskey. They understand our business and go the extra mile to make things happen. It’s a true partnership – almost like a joint venture.

The solution

Crosskey’s eBanking solution is delivered as a service to Marginalen Bank. Crosskey takes responsibility all the way from system hardware down to the end-customer experience. With the internet bank successfully in place, the next step is a mobile banking solution, which is currently under development. The ambition is to create Sweden’s fastest and  simplest mobile bank.

Crosskey combines structure with flexibility. We are also a growing company, and their business understanding supports our growth.

The result

The migration was completed on schedule, and the smoothness of the implementation was beyond expectations. This is a business partnership for a successful long-term future.
