One Underwriting Srl

What One Underwriting Srl does

One Underwriting Srl is a Managing General Agent (MGA) and wholly-owned subsidiary of Aon Group, founded in 2014 to expand specialized insurance solutions in the Italian market. The company operates a B2B2C distribution model that delivers insurance products and services to insurance intermediaries, banks and credit institutions, distribution networks (credit brokers, real estate agents, auto dealers, travel agencies, large retailers), and insurance companies themselves, without charging fixed costs to partners. It holds Lloyd's Coverholder status and maintains multiple facilities and mandates with primary domestic and international insurers, enabling access to specialist insurance products not available on the general market.

The company's core offerings include Donazione Sicura, a first-of-its-kind insurance policy covering properties of donated origin against reduction and restitution actions by heirs; Tsunami, a proprietary multibrand digital platform integrated with banking channels and insurance company management systems that harmonizes operational processes; and Coral, a forthcoming digital distribution platform currently in development. The company also operates insurance departments covering Professional Liability, Accident, Real Estate, Construction, Agribusiness, Legal Protection, D&O, Cyber, Marine/Yacht, Fine Art, Livestock, and Sports Accident lines.

One Underwriting generates revenue through commission-based insurance product distribution (managing the full insurance lifecycle including product creation, risk underwriting, data management, and claims handling) and through platform and technology services provided to partners. The company has approximately 62 employees across four Italian offices (Milan headquarters, Asti, Pordenone, and Rome), having tripled its team size over the past two years. Its competitive positioning rests on the combination of Aon Group affiliation, Lloyd's Coverholder access, proprietary digital platforms, and an integrated partner distribution network.
