Needing high-power, smart automation
Application volume was mounting, and so was the headcount— Washington State Employees Credit Union (WSECU) needed a solution that helped sustain their lending business growth in a way. While their team grew, adding more underwriters and expanding into both direct and indirect auto lending, WSECU needed tools to help them keep up with the flow of applications, become more flexible, and ensure equitable outcomes.
WSECU leadership, along with the internal data analytics and insights team, looked for a partner that could build and deploy lending technology that’s accurate, equitable, fast, and, most importantly, fully explainable and compliant. They discovered that Zest AI could deliver the tools they needed to see instant decisions, efficiency increases, and the capability to confidently decline loans with the appropriate, explainable adverse action codes.
Boosting the member experience with deeper insights
So far, WSECU has been able to automate 70% of their direct auto decisions with Zest AI technology. After becoming comfortable with their direct auto performance, WSECU began to decision indirect applicants with Zest and has been able to automate up to 40% of all applications in their first six months.
