Founded in 2022, Ledgebrook focuses on delivering technology-driven solutions in the Excess and Surplus (E&S) insurance market, streamlining the placement of complex risks for brokers.

The fresh capital will accelerate business expansion, enhance product offerings, and further develop its platform. The funding also coincides with the appointment of Anthony Segal-Knowles as Chief Financial Officer, bringing significant financial expertise from roles at Lazard, the British Treasury, and the International Monetary Fund.

Ledgebrook CEO Gage Caligaris expressed enthusiasm about the new partnerships, stating, “We are thrilled to welcome Duquesne Family Office and the Stephens Group into the Ledgebrook family. Their commitment to long-term thinking aligns well with our vision for what Ledgebrook can be in the coming decades. It is a rare opportunity to be able to bring on partners of this calibre and I could not be more excited.”

The Stephens Group managing director, Ryan Morrow, also praised Ledgebrook’s potential, noting, “We have been fortunate to get to know Gage over the last year, and it is clear he has the chance to build the next great insurance platform. The E&S market and its brokers are long overdue for better technology to place their most difficult risks, and Ledgebrook is building that exact platform.”
