MGA Augmented Names Overall From Atrium as Head of Underwriting

Augmented UW Ltd., the tech-powered managing general agent (MGA) that serves the smart-follow insurance market, has appointed Luke Overall as head of Underwriting.

Overall joins Augmented with over 15 years of experience across both MGA and carrier environments, most recently at Atrium Underwriters where he was a property binders underwriter, according to his LinkedIn profile. He also has held senior underwriting roles at Beazley and CFC.

His multi-class expertise spans property, terrorism, cyber, and liability, with a consistent focus on binder-driven portfolios and strategic underwriting partnerships.

At Augmented, Luke will lead the underwriting team, working closely with brokers and carriers to build data-led portfolios that match capacity to risk. His remit includes shaping the MGA’s technology-enhanced underwriting strategy and supporting the development of digital infrastructure that enables brokers to create their own smart-follow panels.

“Luke brings an exceptional blend of technical underwriting expertise, multi-class experience, and deep market understanding,” said Daniel Prince, CEO of Augmented. “His ability to navigate both broker and carrier dynamics makes him uniquely positioned to lead our underwriting strategy. As Augmented scales across new lines and expands its digital infrastructure, Luke’s leadership will be instrumental in shaping high-performing portfolios and delivering value to our clients and partners.”

Overall’s appointment follows the launch of Augmented in July 2025. The MGA will initially target property and terrorism, before expanding into other lines in 2026.
