ZestyAI today announced an expanded partnership with Steadily, a top-rated insurer for rental properties, to deliver advanced hail and wind risk models that enable more precise underwriting. Building on a successful rollout in 2024, Steadily is broadening its use of ZestyAI’s property-specific insights to better assess storm risk and support growth across high-exposure states.
With operations in all 50 states and $300 million in annualized gross written premium, Steadily is one of the fastest-growing insurers in the U.S.
Steadily first adopted ZestyAI’s Z-HAIL™ and Z-WIND™ models in four high SCS states. With a successful proof of concept, the company is now extending usage to additional states in the coming months.
Datha Santomieri, Co‑Founder & COO of Steadily, said:
“Expanding our use of ZestyAI’s hail and wind models reaffirms our commitment to precision and efficiency in landlord underwriting. These insights help us make informed decisions quickly and manage exposure with greater confidence.”
ZestyAI’s platform predicts the likelihood and severity of storm-related claims by analyzing how localized climatology interacts with individual property characteristics — a sharp contrast to traditional models that rely on ZIP code or territory-level assessments. Each model is built and validated on extensive real-world claims data and delivers transparent explanations of the key factors behind every risk score.
Together, Z-HAIL and Z-WIND help insurers identify storm risk at the parcel level by evaluating roof condition, structural complexity, historical losses, and local storm exposure, enabling the granularity needed to underwrite confidently in volatile regions.
“Steadily is modernizing a critical segment of the market with their customer-centric, tech-forward approach,” said Attila Toth, Founder and CEO of ZestyAI. “We’re proud to support their growth with AI-driven insights that enable better pricing, smarter underwriting, and more resilient portfolios.”
ZestyAI’s severe convective storm models are currently approved by regulators in 19 states and used by leading insurers across the country.
