QUAESTIOS

What QUAESTIOS does

QUAESTIOS is a French wealth management advisory firm operating as a SAS (Société par Actions Simplifiée) with a share capital of €200, headquartered at 229 Rue Saint-Honoré in Paris's 1st arrondissement with a secondary office in Montpellier serving the Occitanie region. The firm provides independent, fee-based advisory services focused on integrated tax optimization, asset structuring, and financial engineering for high-net-worth individuals, business leaders (dirigeants and entrepreneurs managing SAS/SARL structures), liberal professionals, and wealthy families seeking intergenerational wealth transfer. Founded and operated by José-Maria de la Fuente (30 years of experience, including 25 abroad) and Zou de la Fuente (HEC-educated, 20+ years internationally, AMF and CIF certified), the firm combines deep founder expertise with formal regulatory credentials including ORIAS registration, CIF certification, and AMF framework compliance with KYC, LCB-FT, and MiFID II procedures.

The firm's core offering is a 360° patrimonial methodology structured in four proprietary steps — Audit 360°, Scoring & Diagnostic, Strategic Roadmap, and Continuous Monitoring — anchored by a "Score Fiscal QUAESTIOS" (0-100) that quantifies fiscal optimization potential and prioritizes actions by estimated impact. Service lines include comprehensive fiscal optimization across IR, IFI, IS, capital gains, rental income, and transmission; statutory tax reduction schemes (Girardin Industriel, Malraux, Monuments Historiques); business introduction and financing facilitation (apporteur d'affaires) for €1M+ tickets covering fund raising, private debt, and private bonds in France and internationally; and estate/succession planning including Dutreil pact structures. The advisory layer is supported by five interactive web-based simulators — Diagnostic Fiscal Express, Malraux, Girardin, Monuments Historiques, and an Investor Profile Test — and a free Bilan Patrimonial Stratégique lead-generation tool.

QUAESTIOS runs a high-touch, sales-led GTM model with no publicly disclosed pricing. Client acquisition begins with free diagnostics and 15-minute Calendly consultation bookings, progresses to a paid comprehensive audit, and converts into custom-quoted multi-year advisory engagements with continuous monitoring. Demand generation is content-driven through SEO-optimized guides, a monthly newsletter, case studies, and self-serve simulators, supplemented by a VIP referral partnership with Vauban Prestige Immobilier that provides privileged access to premium Occitanie real estate operations. The firm claims 200+ clients, 98% satisfaction, and potential fiscal burden reductions of 15-40% through its integrated 360° strategy.

Revenue model

1. Advisory & Consulting Fees: QUAESTIOS generates revenue through personalized wealth management and fiscal advisory services. The firm provides comprehensive patrimonial analysis, tax optimization strategies, succession planning, and investment structuring. Services are tailored to each client's situation with a structured 4-step methodology. Fees are likely based on engagement scope and complexity, given the bespoke nature of services for high-net-worth clients.
2. Deal Facilitation Fees (Apporteur d'affaires): For business introductions and financing facilitation services, QUAESTIOS acts as an introducer/matcher between project promoters and qualified investors/lenders. The firm qualifies projects, organizes documentation, and facilitates connections with habilitated partners. The firm does not receive funds, collect subscriptions, or make investment recommendations. Revenue from this stream likely comes from success fees or referral arrangements with partner financial institutions.
