HIVE Underwriters, an independent specialty MGA, has expanded into the Political Violence & Terrorism (PVT) insurance market with the hire of Stuart Harmer as Class Underwriter, PVT.
The move marks a further step in HIVE’s evolution into a multi-class specialty MGA, strengthening its knowledge-led underwriting proposition.
The expansion into PVT will be underpinned by advanced technology. Following the appointment of George Stylli as Chief Technology Officer, HIVE has accelerated investment in digital infrastructure and underwriting capabilities.
The PVT team will benefit from sophisticated triage and exposure management systems, enhanced data architecture and dynamic threat assessment tools, reflecting the disciplined approach HIVE applies across its aviation war portfolio.
By combining specialist underwriting expertise with intelligent data infrastructure, the business aims to enable faster decision-making, clearer risk visibility and stronger portfolio control from day one.
Under Harmer’s leadership, HIVE will establish a focused PVT offering centred on disciplined risk selection, data-informed underwriting and close alignment with brokers and capital partners.
The division will concentrate on specialist segments of the political violence and terrorism market where underwriting insight and structural expertise are key to sustainable performance.
Harmer joins HIVE from Atrium Underwriting Group Ltd., where he served as an underwriter. He brings extensive experience in the political violence and terrorism market, alongside strong broker and capacity relationships across the global specialty sector.
In June 2025, HIVE expanded into space insurance with the appointment of Jack Kenneally as Class Underwriter. In January 2026, the MGA announced its expansion into specialty marine insurance with the appointment of Nick Lewis as Marine Chief Underwriting Officer, effective July 2026.
Bruce Carman, CEO of HIVE Underwriters, said, “Political Violence & Terrorism is a highly nuanced class where underwriting judgement, geopolitical insight and structural discipline are critical. In today’s volatile environment, brokers and clients need partners who combine specialist expertise with rigorous exposure management.
“As we expand into PVT, Stuart will be supported by advanced triage and exposure management systems, enhanced data architecture and dynamic threat assessment tools, reflecting the disciplined, technology-enabled approach we apply across our war and aviation portfolio. That combination of deep expertise and intelligent aggregation control gives us real confidence in our ability to manage accumulation risk and respond swiftly to emerging threats.
“The addition of PVT is a natural step in HIVE’s evolution as a multi-class specialty MGA. We deliberately build complementary lines around exceptional underwriters, providing them with the autonomy, technology and aligned capacity to create resilient, high-quality portfolios. Stuart is widely respected for his technical expertise and disciplined approach, and we’re very much looking forward to supporting him as he establishes a distinctive, knowledge-led PVT platform within HIVE.”
