Ledgebrook raises $200 million

Specialty insurance company Ledgebrook has raised $200 million in primary equity financing co-led by Allianz X and Rockefeller Capital Management, with participation from existing investors. Separately, Allianz Re has agreed to enter a multi-year reinsurance agreement with Ledgebrook.

Headquartered in Boston, Ledgebrook writes general liability, professional liability, and specialty cover for mid-sized-market businesses in the E&S market, distributed exclusively through wholesale brokers. Its underwriting platform Blackbird reads submissions, classifies risk, and calculates a technical price, quoting specialty risks, “often in hours rather than weeks,” with experienced underwriters making the final decision.

The company claims to be on track to surpass $1 billion in cumulative premium written since it started writing business in 2023.

“Our vision is for Ledgebrook to be the company that makes the wheels of insurance spin faster. Businesses with complex risk deserve specialized underwriting, rated with rigor and delivered at speed. Our platform lets our underwriters do that with real discipline. Allianz X backing gives us the capital to keep investing in technology and talent. We’re building this company for the long term.” – Gage Caligaris, Founder & CEO of Ledgebrook.

“The industry is applying AI to its simplest risks first, because that is where automation comes easily. We think the larger prize sits at the other end, in complex, hard to place business, where underwriting judgment is scarce and slow decisions cost the most. That’s exactly the gap Blackbird is built to close, and it’s why Ledgebrook fills a meaningful space in our U.S. P&C platform.” – Dr. Nazim Cetin, CEO of Allianz X.
