KatRisk, a US provider of catastrophic risk modelling software to the insurance and financial services industries, has acquired location intelligence and Irish property-level risk assessment firm Gamma.

The deal is expected to bolster KatRisk's expertise in risk analytics, enabling the delivery of more precise insights and next-generation technologies that drive smarter decisions. 

Dublin-based Gamma has built a reputation for delivering trusted property-level risk data, and its flagship platform, Perilfind, is a widely recognised address-level risk assessment, exposure management, and underwriting solution developed in partnership with some of the world’s largest general insurers.

With the acquisition, KatRisk will integrate Gamma’s expertise in property-level visualisation to provide clients with map-based risk insights, dashboards, and enhanced spatial analytics.

The ability to visualise risk at the property level, from flood, wind, and wildfire exposure to other peril data, will provide insurers with unparalleled clarity in risk selection and portfolio management.

“Our acquisition of Gamma is a major step forward in our mission to provide the most comprehensive, high-resolution risk data available,” said Brandon Katz, EVP of Strategy at KatRisk.

“By combining our catastrophic risk models across floods, storms, and fire with Gamma’s location intelligence capabilities, we will deliver an even more powerful suite of tools that improve risk selection, reduce loss ratios, and enhance underwriting efficiency.” 

“The combination of Gamma and KatRisk represents an exciting opportunity for our customers and partners,” said Feargal O’Neill, CEO of Gamma.

“Joining KatRisk gives us access to the world’s leading catastrophe modelers, while opening global markets for Perilfinder. Together, our combined strengths in catastrophe modeling and location intelligence will empower insurers and underwriters to make smarter, faster risk decisions with greater confidence.”

Founded in 2012, KatRisk now has clients in more than 190 countries. The Berkeley, California-headquartered firm and its parent, Technosylva, are backed by private equity groups TA Associates and General Atlantic BeyondNetZero.
