What Groupe Burrus does

Groupe Burrus is a family-owned federation of approximately 50 SMEs headquartered in Strasbourg, France, operating across four business areas: insurance, insurance brokerage, financial management, and technology. Founded in 1923 and led since 1991 by third-generation chairman Christian Burrus, the group has built a pan-European franchise through organic growth and acquisitions, with ~1,500 employees across seven European countries (France, Belgium, Italy, Luxembourg, Switzerland, Monaco, Liechtenstein). Its core products include life savings insurance, borrower insurance, individual provident and funeral coverage under the AFI ESCA brand (France, Belgium, Italy, Luxembourg); insurance brokerage and risk analysis through Diot-Siaci (formed in 2021 from the merger of DIOT and Siaci Saint Honoré) and AFI ESCA Patrimoine; asset management via DÔM Finance (AMF-authorised, €10M–€500M mandates, 20 investment vehicles); and proprietary software through Custy (60+ IT specialists) covering workflow automation, dematerialisation and performance management for insurance brokers, insurers, banks and financial institutions.

The group's revenue is generated through insurance premiums (AFI ESCA entities), brokerage commissions (Diot-Siaci), asset management fees (DÔM Finance), and software/services revenue (Custy). Distribution is overwhelmingly B2B via partner channels: more than 3,500 brokers in France, 700+ wealth management partners, and international reach through EOS RISQ (135+ countries) and Siaci Global Partner (170+ countries). The group recently added direct online sales in Italy. Pricing is not publicly disclosed; contracts are negotiated case-by-case with brokers and institutional partners. In November 2025, Diot-Siaci finalised a new ownership structure with Ardian (45%) joining Groupe Burrus (47%) under joint control governance. Diot-Siaci alone reported €1.31 billion gross revenue for FY2025, up 28% year-over-year, with international revenue growing 34%.
