Founded in 2021 by former actuary Gage Caligaris, the company pairs a next-generation tech stack - which enriches and prefills broker submissions and speeds rating - with experienced human underwriters to write specialty commercial coverages such as general liability, excess liability, professional liability, allied healthcare, and architects & engineers. Having written its first policy in May 2023, Ledgebrook passed a $100M premium run rate and closed an oversubscribed $65M Series C in June 2025, bringing total funding to roughly $119M.
