Clearwater Underwriting has appointed Henry MacHale (pictured) as its first chief executive officer - a newly created role that signals a shift in ambition rather than a change in direction. MacHale, currently chief underwriting officer and head of strategy, international markets at Sompo, is expected to join in Q2 2027.
The appointment is the clearest signal yet that Aquiline Capital Partners, which took a majority stake in the marine MGA in November 2025, is ready to accelerate the business beyond its original marine focus.
MacHale's career at Aspen included three roles that together constitute a distinctive profile: portfolio director for first party and specialty lines, chief underwriting officer for AIUK Insurance, and group chief strategy officer - the last of which, the press release notes, involved "close involvement in the private equity-backed liquidity event process."
That is a description of someone who has been through a PE-driven business transformation and exit at senior level. Aquiline has taken a majority stake in a two-year-old MGA. The profile they have hired for is exactly what that situation calls for.
Richard Young, chief underwriting officer at Clearwater, framed the hire around commercial experience as much as underwriting credentials.
"Henry's understanding of the specialty insurance market, commercial perspective and experience of businesses at different stages of growth and evolution make him a natural fit for Clearwater," he said.
Clearwater was founded in 2023 by Young, a former Beazley underwriter, and began underwriting in 2024. Aquiline's majority investment in November 2025 - its 12th MGA and fifth in the London market, according to Aquiline partner Daniel Flueckiger at the time - marked the transition from founder-led start-up to PE-backed growth platform. MacHale is the hire that completes that transition at the executive level.
MacHale said he had been impressed by what the business had built.
"I have been hugely impressed by the quality of the business, the expertise of the team and the ambition for its future," he said. "I look forward to working alongside the team to build on these foundations and deliver on Clearwater's ambitions for the next phase of its development."
Clearwater's strategy is to expand from marine into a broader range of specialty and niche classes, through new underwriting capabilities, selected class and market expansion, and targeted M&A. It currently writes marine hull, marine war, upstream energy, subsea cables - via InterProtect, its dedicated cable binder launched in July 2025 - and crisis management cover for active assailant and terrorism and political violence risks, added from August 2026.
The multi-line ambition, supported by Aquiline's capital and now a CEO with the right growth-phase experience, suggests the class list will broaden materially over the next two to three years. Broker and capacity relationships are named explicitly in the press release as central to that growth - which is both a statement of intent and an indication of how the business intends to compete.
For brokers not yet trading with Clearwater, the MacHale appointment is the moment to look again. A PE-backed MGA transitioning from start-up to institutionalised platform tends to move quickly once the executive architecture is in place - and the class range available through it in 12 months' time may look different from what it is today.
