WILMINGTON, DE — Global Indemnity Group LLC (Nasdaq: GBLI) has appointed insurance industry executive Jessica E. Buss as chief executive officer, placing her in charge of expanding the company’s specialty insurance operations and deploying its underwriting technology across a national distribution network.
Buss succeeds Joseph W. “Jay” Brown, who had led the Wilmington-based insurer since 2022. The appointment takes effect immediately and extends to Global Indemnity’s two operating platforms, Katalyx Holdings LLC and Belmont Holdings GX Inc.
The leadership change comes as Global Indemnity seeks to expand its excess and surplus lines business, recruit specialty underwriting teams and increase the use of proprietary technology across its insurance operations.
Buss joined Global Indemnity’s board of directors Oct. 26, 2026, and will retain her board seat while serving as chief executive.
Her appointment brings an executive with experience in specialty insurance expansion, acquisitions and commercial underwriting to a company seeking to build on infrastructure assembled over more than two decades.
As chief executive of GuideOne Insurance, Buss doubled the company’s premium volume, exceeding $1 billion, while developing a $400 million excess and surplus lines business.
She also previously served as chief executive of Argo Group and Open Lending. At Open Lending, she held the positions of board chairman and audit committee chair before becoming CEO.
Earlier in her career, Buss served as chief operating officer and chief financial officer of Rockhill Insurance, where she led the company’s sale to State Auto Mutual at 1.6 times book value.
She subsequently managed State Auto Mutual’s $1.5 billion commercial and specialty insurance division.
Buss is a certified public accountant and holds a directorship certification from the National Association of Corporate Directors.
At Global Indemnity, her responsibilities will include expanding Katalyx’s excess and surplus lines managing general agency operations through wholesale, retail and direct-to-consumer distribution channels.
The company’s existing network encompasses more than 350 wholesale agency offices and 12,000 retail agents, alongside a direct-to-consumer platform.
Global Indemnity operates five insurance carriers, each carrying an A (Excellent) financial strength rating from AM Best. According to the company, its carriers have maintained that rating for more than 23 years.
The insurer also reports a 23-year record of top-quartile underwriting loss ratios, a measure of claims expenses relative to earned premiums.
Those underwriting operations form part of a specialty insurance platform developed over 23 years under Fox Paine & Company, whose affiliate is Global Indemnity’s largest shareholder.
The company’s expansion strategy increasingly centers on Kaleidoscope, a proprietary underwriting, policy administration and data platform developed over the past four years.
Global Indemnity is rolling out the system to agency partners as it seeks to streamline underwriting and support additional specialty insurance business.
Kaleidoscope incorporates artificial intelligence-enabled underwriting capabilities designed to evaluate and price risks outside traditional binding authority arrangements.
Such arrangements typically permit designated agents or intermediaries to issue coverage within predetermined underwriting guidelines. The company’s technology is intended to support assessment of risks that fall outside those established parameters.
Saul Fox, Global Indemnity’s founder and chairman and founder and chief executive of Fox Paine & Company, identified Buss’ experience building specialty insurance businesses as central to the leadership decision.
“She knows how to make money in specialty casualty, how to attract first-rate talent and how to use technology to grow faster and run leaner than the competition,” Fox stated.
He also credited Brown with preparing the insurer for its next phase of development.
Brown, who moved from the company’s board into the chief executive position four years ago, oversaw preparations for the rollout of Kaleidoscope and the company’s increased emphasis on technology-supported underwriting.
“With Kaleidoscope now rolling out to our agency partners, Jessica takes over at the right time,” Brown stated.
Buss indicated that her immediate priorities would involve expanding the company’s existing underwriting and distribution capabilities while strengthening relationships with agents and specialty insurance partners.
“GBLI has what matters most in specialty insurance: disciplined underwriting, strong carriers, deep agency relationships and technology built for this market’s future,” Buss stated. “My job is to build on it.”
The transition places Global Indemnity’s growth strategy under an executive with experience scaling specialty insurance operations as the company seeks to use its existing carriers, agency relationships and underwriting technology to expand its market presence.
