Hadron Appoints Liesel Carvajal as Group General Counsel and Ed McGough as Chief Information Officer

Executive Appointments Reflect Hadron’s Disciplined Growth Strategy and Continued Investment in Global Platform Expansion

LITTLE ROCK, Ark.--(BUSINESS WIRE)--Hadron, a modern specialty insurance carrier setting a higher standard in delegated underwriting authority, today announced the appointments of Liesel Carvajal as Group General Counsel and Ed McGough as Chief Information Officer.

Three years of deliberate platform-building across its global operations have established Hadron as a carrier built for the long term. These appointments accelerate that trajectory, bringing the legal, regulatory, and technology leadership to scale a multinational specialty platform with discipline and precision.

"The delegated authority market is at an inflection point,” said Sam Reeder, Chief Executive Officer of Hadron. “The carriers that will define the next decade are the ones investing in governance and infrastructure ahead of scale, not when they have to. Liesel and Ed are exactly the kind of leaders you bring in when you're building for the long term. I also want to recognize Steve Stephan, whose foundational work on our legal and compliance infrastructure made this next chapter possible. We wish him well in his retirement."

Liesel Carvajal Named Group General Counsel

As Group General Counsel, Liesel Carvajal joins Hadron's Executive Leadership team, where she leads all legal, regulatory, compliance, and corporate governance functions across the company's global operations. In her role, she will guide the company's continued international expansion, support strategic transactions and carrier operations, and strengthen the governance and regulatory infrastructure that underpins Hadron's long-term growth strategy to ensure the company operates to the highest standards across every jurisdiction in which it does business.

Prior to joining Hadron, Carvajal served as General Counsel, US Insurance at AXA XL, the property and casualty division of AXA, where she oversaw the legal affairs of the U.S. Insurance business. She brings extensive insurance industry experience, having previously held legal roles at Arch Insurance Group, AIG, and The Hartford. She began her career as a litigation associate at Wilson Elser in New York City.

Carvajal holds a Juris Doctor from Brooklyn Law School and a Bachelor of Science from the University of Richmond. She is admitted to the New York and New Jersey bars and holds the Registered Professional Liability Underwriter (RPLU) designation.

“The specialty insurance market is going through a period of real change, and the regulatory and governance questions that come with international expansion are increasingly central to how carriers differentiate themselves," said Carvajal. “Hadron’s focus on continuing to build a strong legal and compliance infrastructure while growing to scale is crucial to its success and exactly what this market needs."

Ed McGough Named Chief Information Officer

Ed McGough is an insurance technology expert, having led large-scale data projects for many years before moving into CIO and CTO roles with AIG and later with Insurtech startups. His industry experience includes delivering technology solutions across a broad range of insurance lines and markets, globally.

McGough joins as Hadron catapults into its next phase of growth, bringing the technology leadership to match the company's expanding ambitions. He will lead Hadron's technology function, with a particular focus on scaling the company's data architecture and releasing the full potential of Collider, Hadron's proprietary underwriting and portfolio management platform designed to deliver speed, precision, and transparency across the risk lifecycle.

“Hadron has taken an infrastructure-first approach to building a modern specialty carrier, combining underwriting expertise with data and technology to enable smarter risk selection and portfolio visibility,” said McGough. “Collider represents a natural extension of that strategy, bringing greater speed and precision to underwriting and portfolio management while maintaining the transparency and control that capital partners expect.”
