## Overview

Gamma Risk is a property-level risk analytics and location intelligence company serving insurance underwriters and financial institutions across the UK and Ireland. Founded in 1993 as a GIS technology spinout from Trinity College Dublin, the company has spent over 30 years developing geospatial tools that help carriers assess property-level perils, standardize address data, and quantify climate-related exposures.

The company's core offering is Perilfinder, a platform that delivers instant property-level peril assessments with RAG (Red, Amber, Green) scoring across perils including flood, subsidence, windstorm, and fire. Perilfinder integrates into insurer underwriting workflows via an API, enabling property risk decisions at point of bind. A sister company, Autoaddress, provides address matching and geocoding services through the AddressLink API. Gamma also publishes spatial analysis of climate and flood risk for mortgage lenders.

In May 2025, Gamma was acquired by KatRisk, a global catastrophe modeling software provider backed by TA Associates and General Atlantic BeyondNetZero, to expand KatRisk's property-level visualization and location intelligence capabilities. KatRisk itself was acquired by Technosylva, a wildfire simulation company, in November 2024. Gamma reported 100% customer retention on the Perilfinder platform since 2008, reflecting durable demand for its location intelligence tools in the Irish and UK insurance markets.
