Alliant Credit Union
In order to realize its mission to become a digital credit union, Alliant Credit Union teamed with WillowTree to create mobile apps that deliver a great user experience and seamlessly span the range of devices a single member might use in a day.

Alliant Credit Union, with more than 450,000 members and over $11 billion in assets, is a not-for-profit financial cooperative. The credit union has set a vision to be a digital-first credit union, and recognized that transformation would be necessary to ensure the attraction and retention of an increasingly digital public that includes financially-savvy consumers of all ages.

Perfecting an Omni-Channel Experience

The apps offer a simple way to view and manage account information, make transfers, manage credit cards, and set travel notifications, delivering a way to bank in the consumer’s channel of choice. Using Xamarin leveraged the existing skill sets of Alliant’s growing team (many of whom were already experienced with Microsoft technologies), allowing them an easy way to work with WillowTree while ensuring a totally seamless omni-channel end-user experience.

Key Takeaways

WillowTree enables Alliant's digital transformation

By delivering a customized mobile experience, Alliant is better able to engage its digitally-savvy membership, which is vital given the credit union’s rapid growth of more than 10% per year for the past two years. The successful launch of new digital tools has enabled the strategic closure of the majority of Aliiant’s physical branches.

Security is paramount in the financial services industry

Leveraging cutting-edge best practices in financial security, such as second-layer data encryption and early adoption of Android’s fingerprint APIs (and other biometrics), the apps give members peace of mind while ensuring that Alliant protects customer data. WillowTree implemented modern security features such as facial and thumbprint recognition as well as a 6-digit PIN for a convenient and highly secure experience.

Ongoing partnership matures an Agile culture

WillowTree became an embedded part of the team, co-developing with Alliant’s in-house security, dev, and API teams. The WillowTree partnership has greatly boosted agility for Alliant’s team, helping them close in on their goal of deploying new services monthly.
