What KACIUS does

KACIUS is a Paris-based independent wealth management advisory firm (SARL, €130,000 capital) founded in 2007 and operating under the Groupe Descolonges umbrella. The firm is co-directed by Son and Lân Descolonges and provides open-architecture advice to French individual investors across three integrated service lines: (1) tax-incentive real estate (Malraux & Monuments Historiques, Déficit Foncier, LMNP/LMP, Denormandie, Pinel Plus, Nue Propriété, and the new Jeanbrun device); (2) tax-advantaged financial placements (Assurance Vie, PER, SCPI, Girardin Industriel in DROM-COM territories, SOFICA, crowdfunding immobilier); and (3) wealth engineering (SCI formation, donations, matrimonial regimes, succession planning). Distribution runs through a sedentary Paris support team, a network of 15 CGPI partner advisors, a B2B prescriber platform (KACIUS Partenaires), and a self-serve property search portal (KACIUS Invest) surfacing more than 1,121 programs.

Revenue is generated primarily through commission retrocessions of up to 100% from product providers (insurers, asset managers, banks, and property developers) on entry/exit, subscription, management (0.2%-1.5%), and arbitration fees, plus real estate transaction commissions and business-introduction fees. Advisory engagements are priced per mission letter (lettre de mission). The firm holds ORIAS registration (09 051 226), ANACOFI membership, AMF CIF authorization, and AIG-backed professional liability insurance. As of the available data, KACIUS has accompanied 1,887+ clients over 17+ years and ranks 4th in the Gestion de Fortune Palmarès, but discloses no revenue, headcount growth rate, or external funding.

Revenue model

1. Retrocessions de commissions: KACIUS receives commission retrocessions from product providers (insurance companies, asset management firms, banks, and property developers) up to 100% of the commissions charged by these providers. This includes entry/exit fees, subscription/redemption fees, account management fees, arbitration fees, and management fees (rates between 0.2% and 1.5%).
2. Frais de transaction immobilière: For real estate transactions following wealth management advice, KACIUS acts as a real estate agent and receives commission retrocessions from property developers up to 100% of their commissions.
3. Commissions d'apport d'affaires: As a business introducer for service providers, KACIUS receives commissions paid by service providers for client referrals. For non-independent CIF advice or intermediation acts, the advisor retains a fraction of the fees initially charged by the product promoter.
4. Honoraires de conseil: A mission letter (lettre de mission) establishes adapted pricing for the advisory services provided. The company mentions that for Girardin Industriel investments, tax reduction can reach 110% to 125% of the amount invested.
