What Lsn Assurances does

LSN Assurances is a Paris-headquartered, independent insurance brokerage firm organized as a Société par actions simplifiée (SAS) under French law (RCS Paris 388 123 069), regulated by the ACPR and registered with ORIAS (n° 07 000 473). The firm traces its origin to La Sécurité Nouvelle and now operates as part of the Diot-SIACI Group following the finalized merger of DIOT-LSN with SIACI Saint Honoré. It runs three regional poles — Lyon, Bordeaux, and Lille — alongside its Paris headquarters at 39 rue Mstislav Rostropovitch, and maintains international program placement capability through the EOS Risq broker network covering 135+ countries.

The firm operates a relationship-based advisory brokerage model in which dedicated account managers conduct contractualized risk-mapping audits before placing coverage. Its product portfolio spans core P&C lines (civil liability, property, auto, construction, credit, aviation, transport), employee benefits (health, supplementary retirement, key person, manager redundancy, pension), and specialty segments. Two wholly-owned operating subsidiaries provide vertical depth: NEOTECH Assurances serves digital services and high-tech firms (selected by SyntecNumérique), and LSN Ré Walbaum provides reinsurance brokerage with over 30 years of experience to insurance companies and mutuals. Customer segments are organized vertically across regulated professions (notably notaries), commercial and industrial enterprises, professionals, associations and foundations, individuals, and the construction sector, supported by segment-specific portals (Espace Notariat, LSN Services Santé).

Revenue is generated through brokerage commissions on insurance products placed with carriers (transaction-fee model), with pricing structured as multi-year contracts tailored to client risk profiles rather than standardized rates. Distribution is primarily direct via the account-manager channel, supplemented by self-service portals for specific verticals and by the EOS Risq channel for multinational placements. The firm self-describes as an "independent family group on a human scale," and is operationally integrated into the broader Diot-SIACI corporate platform.
