Colin Johnson joins Hadron as CEO of international business

Hadron Insurance , a modern insurance carrier specializing in delegated authority, has named Colin Johnson as CEO of its International operations. Johnson will oversee Hadron UK Insurance Company (HUKIC), subject to regulatory approval, and its affiliates, with a focus on building a leading franchise for the delegated authority market in the UK and EU.

The announcement follows the launch of new programs across the US and UK, backed by a growing panel of reinsurers. Previously, Johnson served as CEO of Accredited Insurance (Europe) Limited (AIEL), where he expanded the business to over $1 billion in annual GWP through a diversified portfolio of MGAs.

Hadron projects over $200 million in written business across its platforms for 2024, with higher run-rate figures expected for 2025. Its strategy emphasizes disciplined underwriting, technology-driven efficiency, and strong collaboration with underwriting teams and risk capital providers.

“Colin is an exceptional leader, and I am pleased to have him join our team to help accelerate our growth in the UK and other international markets in time. As we look toward growing our business in 2025 and beyond, Colin’s expertise will be invaluable to me and the rest of the team.” – Sam Reeder, CEO, Hadron.

Hadron, backed by more than $250M in capital from Altamont Capital Partners and other institutional investors, was launched in the US in late 2023. Hadron provides both lead and primary insurance services as well as capacity to managing general agents (MGAs) or managing general underwriters (MGUs) that want to offer small-to-medium-sized businesses (SMBs) protection for risks that standard insurance carriers won’t cover.
