WorkingVendor case studyVendor ↗

Problem

Manual underwriting slowed loan decisions and limited Suncoast's ability to serve more applicants. Most decisions required staff intervention.

Approach

Suncoast adopted Zest AI's machine-learning underwriting software to evaluate applications beyond credit scores alone. It subsequently centralized underwriting across its branches. Analysts focused more time on complex applications.

Results

60%share of loan decisions automated, previously 30%, according to Zest AIVendor case study[1]
27Kstaff hours saved annually, according to Zest AIVendor case study[1]

Takeaway

Higher automation supported a change in how underwriting staff were organized. The reported time savings did not establish changes in loan losses.
