Ategrity Specialty Insurance Company Holdings is a specialty property and casualty insurance holding company that underwriters commercial property and casualty coverage exclusively through the excess and surplus (E&S) market, serving small to medium-sized businesses across the United States. The company distributes its products through licensed surplus lines brokers and wholesale agents using a proprietary "productionized underwriting" model that combines technical underwriting expertise with a centralized, cloud-based operating platform to standardize and automate key tasks such as submission intake, risk classification, pricing, and policy administration. The company generates revenue from gross written premiums across a diversified portfolio of casualty and property coverages in selected industry verticals, manages risk exposure through reinsurance arrangements including quota share and excess-of-loss structures, and operates through a dedicated technology platform to enable both automated processing for standardized risks and underwriter-assisted decisions for higher-complexity accounts.
