On April 17, 2025, MGT Insurance Company filed to introduce a new Businessowners (BOP) program in California, targeting small and medium-sized businesses. The “Mainstreet Businessowners Program” leverages ISO loss costs and rules, with MGT filing proprietary exceptions and endorsements including cyber liability, assault/battery, and canine exclusions.

MGT positions itself as a tech-forward, broker-focused insurer led by a team with experience at Liberty Mutual, Travelers, Bold Penguin, and Vouch. It distributes primarily through retail brokers and emphasizes disciplined underwriting. “We believe that one competitor in particular, AmGuard Insurance Company, is an appropriate benchmark given that their rating structure mimics ISO, they offer ISO coverage forms, and their BOP product appetite aligns with this program.”

As part of its filing, MGT benchmarked AmGuard Insurance Company’s program—citing its ISO-based rating and similar appetite—as a justification for deviations from ISO General Liability Territory Modification Factors. The company will also use the LexisNexis Attract B505 non-FCRA insurance score model.
