Reinsurance broker modernizing analytics and operations at scale

Insurance London, England 51–200 employees Founded 2025 Privately Held

Willis Re is a reinsurance broker operating with a 50-person ops-and-data-focused team, built around Excel, Python, R, SQL, and Verisk. The hiring velocity—6 roles in 30 days across ops, data, and finance, tilted toward mid and senior levels—paired with active projects in catastrophe modeling, analytics capability building, and carrier onboarding, suggests infrastructure maturation rather than proof-of-concept. Regulatory reporting compliance and portfolio optimization appear as persistent friction points, consistent with a broker scaling operations faster than processes.
