Zest AI

Zest AI builds automated, explainable credit-underwriting models for banks and credit unions, emphasizing transparency and fair-lending compliance as a more inclusive alternative to legacy scorecards. Founded in 2009 and headquartered in Los Angeles, Zest has a strong footprint among community lenders and credit unions. Its core pitch is that machine-learning underwriting can expand access to credit while remaining explainable enough to satisfy fair-lending law — a balance that black-box models struggle to strike.
