ZestyAI today announced Z-SPARK™, an AI-powered model that predicts non-weather fire risk at the individual property level.

The model evaluates the factors that influence ignition and fire spread to help insurers identify the structures most likely to generate costly fire losses.

Most insurers still evaluate fire risk using neighborhood or territory level averages and limited historical loss data, even though risk can vary dramatically from one property to the next. Without property-level insight, insurers struggle to price risk accurately, increasing the likelihood of adverse selection and unexpected losses.

In 2023, $25 billion in property losses occurred from non-weather-related fire incidents from sources such as grills, appliances, heaters, and electrical faults.

Z-SPARK applies modern fire science and property-level intelligence to analyze how building materials, maintenance conditions, surrounding structures, local fire response capacity, and climate drive ignition and fire spread. 

The model predicts both the probability of ignition and potential loss severity using advanced machine learning trained and validated on millions of real fire incidents and verified insurance claims.

With these insights, insurers can:

• Price with precision — align premiums with true property-level fire risk rather than broad geographic averages
• Streamline operations — support straight-through processing for low-risk properties
• Prioritize underwriting resources — focus manual review and inspections where risk warrants closer scrutiny
• Expand confidently — write business in challenging markets with a clearer view of actual exposure
• Protect portfolio performance — proactively manage concentration risk before losses accumulate

Z-SPARK delivers 30× greater risk differentiation than traditional territory-based models.

“Non-weather fire is one of the most costly and least understood risks in property insurance,” said Kumar Dhuvur, Founder and Chief Product Officer of ZestyAI.

“Two homes on the same street can have dramatically different fire risk depending on how they were built, maintained, and what surrounds them. Yet most insurers still evaluate that risk using community-level scores. Z-SPARK reveals those hidden differences so insurers can make decisions based on the actual risk at each property.”

ZestyAI’s Z-FIRE wildfire model is widely used by insurers to assess catastrophic wildfire exposure. Z-SPARK extends that expertise to everyday building fires, applying the same property-level intelligence to the most costly source of insurance loss.

Together with models for hail, wind, severe convective storms, and water damage, Z-SPARK expands ZestyAI's suite of AI-powered capabilities across the most costly perils affecting insurance portfolios. Combined with ZORRO Discover — which applies agentic AI to help insurers research markets, prepare filings, and act on risk intelligence faster — the ZestyAI platform gives insurers a comprehensive view of property-level risk and the tools to act on it across underwriting, pricing, and portfolio management.

ZestyAI today announced that American European Insurance Group (AEIG) has selected its suite of regulatory-approved AI models to enhance underwriting, pricing, and exposure management across its multi-state property portfolio.

Through the ZestyAI platform, AEIG has adopted models for non-weather water (Z-WATER™), hail (Z-HAIL™), and wind (Z-WIND™), along with Z-PROPERTY™ to deliver property-level risk insight.

ZestyAI’s models are built, trained, and validated on carrier-contributed loss data and analyze the interaction between property characteristics, environmental conditions, and peril behavior to predict claim frequency and severity at the individual property level. Carriers apply these insights at new business and renewal to sharpen risk selection, improve pricing alignment, and manage portfolio concentration. ZestyAI’s models have secured regulatory approvals that enable transparent and defensible use in underwriting and pricing.

“As we operate across states with varied exposure profiles, we need consistent, property-level insight into what drives losses across wind, hail, and non-weather water,” said Steve Hartman, President and CEO of AEIG.

“ZestyAI gives us the precision to align underwriting and pricing with expected loss performance, support our agent partners with greater transparency, and maintain disciplined growth. Corporate experience alone is no longer sufficient to intelligently compete in a crowded marketplace, and the ability to leverage both traditional and non-traditional data in best-in-class account underwriting and pricing is a requirement for sustained profitability.”

“Regional insurers like AEIG are balancing expansion with the need to stay highly disciplined in how they evaluate property risk,” said Attila Toth, Founder and CEO of ZestyAI.

“By grounding underwriting and pricing decisions in verified, property-level intelligence, AEIG can expand across diverse exposures with confidence while protecting portfolio performance.”

ZestyAI has been named one of the Everest Group’s Top 50™ Property & Casualty (P&C) Insurance Technology Providers for 2026, marking the second consecutive year the company has been recognized for helping shape the future of insurance technology. 

Each year, Everest Group evaluates hundreds of providers across the global insurance technology landscape. The Top 50 ranking highlights providers demonstrating strong market momentum, broad industry impact, and continued investment in advanced technology.

Over the past year, ZestyAI has significantly expanded its platform and product capabilities to help insurers understand and manage property risk with greater precision. This includes the launch of ZORRO, ZestyAI’s agentic AI platform that enables insurers to research markets, analyze regulatory filings, and act on risk intelligence faster.

Everest Group also recognized ZestyAI within the Property and Location Intelligence category—solutions that help insurers evaluate structural, environmental, and catastrophe risk at the individual property level to improve underwriting, pricing accuracy, and operational efficiency.

ZestyAI’s AI-powered models help insurers assess exposure across the most costly perils affecting property portfolios, including wildfire, hail, wind, severe convective storms, and non-weather water damage. Together, these capabilities give insurers a more complete view of risk and the tools to act on it across underwriting, pricing, and portfolio management.

As AI moves from experimentation to enterprise deployment across the insurance industry, ZestyAI continues to invest in technologies that help insurers operate with greater precision, transparency, and confidence.

ZestyAI today announced that Harford Mutual Insurance Group (HMIG) has selected the ZestyAI Platform to enhance property-level exposure insight across its commercial portfolio.

Two insurers operating in hurricane-exposed coastal markets — Southern Oak Insurance Company and Lilypad-Centauri Insurance — are using the ZestyAI platform to bring greater structure-level insight to underwriting and portfolio oversight

As catastrophe volatility intensifies in states like Florida, insurers are increasingly turning to property-level intelligence — including roof condition, parcel characteristics, and structural features — to better understand exposure and manage accumulation risk.

Southern Oak Insurance Company expanded its partnership with ZestyAI following nine months of portfolio impact using Z-PROPERTY™ to analyze structural condition across its Florida homeowners portfolio.

Lilypad-Centauri Insurance adopted Roof Age and Z-PROPERTY™ to improve visibility into roof replacement history, parcel characteristics, and structural exposure across its coastal homeowners and dwelling fire portfolios.
