Zest AI is the only complete AI solution built to generate faster, fairer, and better lending down the credit spectrum.

FAQs

Zest AI uses powerful machine learning to deliver accurate insights on your borrowers and allow you to automate more of your lending process. Machine learning uses more data from the credit bureau report you already have, and better math to allow for smarter, more inclusive, and faster lending decisions.

Industry models use around 20 data features to assess a borrower and deliver a 3 digit score. Zest AI uses closer to 300 variables to create a clearer, more accurate picture of your member. Zest AI is able to look at a longer duration of credit history, meaningful data correlations and trends over time to produce a proven, more accurate risk assessment.

Zest AI can help automate the lending process by integrating with the most popular LOS’ or your credit reporting bureau. However, integration with an LOS is not required to use Zest AI.

A credit union can start scoring in a matter of weeks. The exact timing depends on the specific configuration of the solution.

In terms of implementation and deployment, the IT lift is minimal to none from the credit union side. The Zest team coordinates the implementation and onboarding with the credit union at every step.
