Documented cause
Zest AI (formerly ZestFinance) founded by Google's former CTO tried to disrupt consumer lending with ML underwriting. The original direct-lending model ran into regulatory trouble with high-interest rate loans to subprime borrowers. The company pivoted to licensing its ML underwriting engine to banks and credit unions. That model worked modestly but required long enterprise sales cycles. A third pivot to BNPL underwriting software came too late — the BNPL market cooled before Zest could sign sufficient enterprise customers. The company ended its decade-long journey without achieving the scale its founding ambition implied.
Lesson
“ML underwriting models require regulatory approval for each use case — serial pivots do not accelerate the compliance clock.”
