Coterie Insurance, a tech-enabled, data-powered managing general agent (MGA) specialising in property and casualty (P&C) commercial insurance for small businesses, has named Brett Saternus, FCAS, as its new Chief Underwriting Officer (CUO).
Saternus brings more than 15 years of underwriting and insurance leadership experience spanning specialty carriers, insurtech MGAs, and commercial insurers.
During his career, he has held senior underwriting leadership positions at Canopius US Insurance, Rainbow MGA, and Rhino.
In his new role at Coterie Insurance, Saternus will oversee underwriting strategy, portfolio management, and capacity alignment, supporting the company’s efforts to drive profitable growth and further strengthen its underwriting capabilities as it expands its small commercial platform.
The firm said that Saternus’s appointment reflects its continued investment in senior leadership that combines deep insurance expertise with technology-forward execution.
“His arrival strengthens the company’s executive team as Coterie continues building a modern, agent-friendly small commercial insurance platform grounded in data, underwriting discipline, and operational rigour,” Coterie added.
David McFarland, Founder and CEO of Coterie Insurance, commented, “Underwriting discipline is foundational to how Coterie creates value for agents, carriers, and small business owners.
“Brett brings the rare combination of actuarial depth, program insurance experience, and operator judgment that matters in small commercial insurance.
“He has built teams, managed capacity, worked across carrier and reinsurer relationships, and translated data into clear underwriting decisions. His leadership will help us scale with focus, clarity, and long-term profitability.”
Saternus added, “Coterie has built a model for small commercial insurance that puts data, technology, and underwriting discipline to work for agents and small businesses.
“I am excited to join a team focused on making underwriting more precise, transparent, and scalable, while helping partners grow profitably and deliver coverage with speed and confidence.”
