Luminor launches E&S property MGA
Luminor launched as a new managing general agent focused on the U.S. excess and surplus commercial property market, targeting catastrophe-exposed and hard-to-place risks through a wholesale-only distribution model.
The MGA is backed by the D. E. Shaw group and supported by a panel of reinsurers and capital providers. According to the company, the platform combines experienced E&S property underwriting leadership with proprietary data, analytics, and AI-driven underwriting infrastructure designed to support submission intake, pricing, risk selection, and portfolio management.
Luminor said roughly half of its team comes from software engineering, actuarial, and data science backgrounds, with its underwriting platform automating document review, data extraction, and other manual underwriting tasks.
The founding team includes Matt Booker, former Executive Vice President and Underwriting Manager for Property and Inland Marine at Westchester, a Chubb company; Bradley Winfield, former Head of U.S. Property, Marine, and Programs at Canopius USA; and John Lavin, formerly Executive Vice President, U.S. Property E&S at Sompo International.

“Luminor exists to redefine what an MGA can be – fully independent, data-driven, and built to last. The D. E. Shaw group’s vision for this business matches our own: that the best underwriters in the market, given the right tools and the right capital behind them, can do something the industry has never seen before.” – Matt Booker, CEO.
“Our focus is one hundred percent E&S with no retail conflicts and no broker ownership. We are applying carrier-level rigor to wholesale distribution, supported by real-time data and analytics that give our capital partners the visibility they deserve.” – Bradley Winfield, Co-Chief Operating Officer.
“Luminor is designed to be a long-term partner to brokers and capital alike. It is built for volatility, backed by world-class institutions, and staffed by a team that has spent careers earning the trust of this market.” – John Lavin, Co-Chief Operating Officer.
