Corgi suits technology startups wanting packages organized from pre-seed through growth, with dashboard changes as the business grows; firms seeking only a direct single-carrier policy should compare alternatives. Issuers vary by product and state.

MMA’s source names E&O, architects and engineers, and lawyers professional lines. A service firm should compare Corgi’s broad catalog category with the particular MMA professional line proposed for its services and professional duties.

MMA’s source identifies those latter professional categories alongside E&O. If timing or a licensed specialty matters, ask Corgi which catalog route fits and ask MMA to identify the proposed line and its expected quote steps.
