Ep 310: Kat Gordienko, Co-founder & CEO, Builty

In Episode 310 of the FNO: InsureTech Podcast, co-host David Prejeant sits down with Kat Gordienko, Co-founder and CEO of Builty, to explore one of the most overlooked and underutilized data sources in insurance: building permits. What began as a personal home improvement project during the pandemic ultimately sparked the creation of a company focused on transforming fragmented permit records into actionable intelligence for insurers. 

Kat shares her journey from analyzing streaming data at Netflix to tackling the complex world of permit data, where information is scattered across more than 20,000 jurisdictions, filled with inconsistencies, abbreviations, and unstructured records. She explains how Builty uses AI and proprietary data models to normalize this information and turn it into meaningful risk insights for underwriting, claims, and property intelligence. 

The conversation explores how permit data can reveal information that traditional property data sources often miss, including electrical upgrades, plumbing improvements, fire protection systems, and commercial property modifications. Kat also discusses how Builty is working with insurers, leveraging NVIDIA's Inception program, and uncovering new ways permit data can help carriers better understand future risks before they appear in claims history. 

Along the way, David and Kat dive into some of the most unusual building permits ever filed, including catios, residential helipads, falconries, and fur storage facilities, proving that permit data can be both insightful and entertaining.
