Quick Summary
ZestyAI has secured regulatory approval for its Z-WATER property-level risk model in over 20 U.S. states. This technology addresses the $15 billion non-weather water peril by providing 18x better risk segmentation than traditional methods, allowing insurers to price individual property risks with unprecedented precision and transparency.
How Does Z-WATER Solve the Non-Weather Water Crisis?
Non-weather water risk is now the fourth-costliest peril in the homeowners insurance sector, resulting in over $15 billion in annual losses. ZestyAI solves this by moving beyond outdated territory-based proxies. The Z-WATER model utilizes computer vision and aerial imagery to analyze specific property characteristics, permitting history, and infrastructure context. This granular approach identifies risks like burst pipes and appliance failures before they escalate into catastrophic claims. Key metrics include:
- 18x greater risk segmentation compared to traditional age-based methods.
- Coverage for over one million annual claims.
- Addressing an 80% increase in claim severity seen across the industry.
Why Are Regulators Approving Property-Level AI Models?
Regulatory acceptance is accelerating as carriers seek more transparent and accurate ways to manage rising property loss costs. With recent approvals in states like Nevada, Ohio, and Oregon, ZestyAI has now surpassed 200 total regulatory approvals across its entire suite of risk models. This shift indicates that AI-driven transparency is meeting the rigorous standards expected by state insurance departments. By evaluating localized climatology and specific home data, ZestyAI provides a defensible framework for individual property rating that benefits both the insurer's loss ratio and the consumer's pricing accuracy.
"Non-weather water losses place real pressure on carriers' books, but they're also highly preventable when you understand where the risks actually lie," said Bryan Rehor, Senior Director of Regulatory and Government Affairs at ZestyAI. "The growing regulatory acceptance of Z-WATER reflects a broader shift toward models that can identify meaningful differences in risk from one home to the next while providing the transparency regulators expect.”
