What STAR INVEST does

STAR INVEST is a French financial services group founded in 1994 that specializes in structuring and distributing tax-advantaged investment products under the Girardin Law for French overseas territories (Outre-Mer).

Since inception, STAR INVEST has financed over €4 billion in investments, obtained 750+ fiscal approvals, and managed 1,700+ portage holding companies.

The company's core offering is the Dispositif Girardin, operating across three pillars: Girardin industriel (industrial investment, available in variants with prior fiscal approval at 17% yield or plein droit at 19% yield), Girardin logement social (social housing, offering up to 50% tax reduction), and bond issuance products. Underlying technology consists of a proprietary fiscal engineering platform and the YSIDIS partner network platform, which connects 450+ wealth management advisors (CGPs) to available operations, client reservations, and documentation. A separate extranet portal supports CGP portfolio management and investor documentation.

STAR INVEST operates a B2B2C distribution model, earning transaction-based structuring fees on investment operations and ongoing managed services fees on its 1,700+ portage companies. Its end customers are high-net-worth individuals and corporations seeking French income or corporate tax reduction, accessed exclusively through independent wealth management advisors. The company runs weekly Thursday webinars, participates in flagship industry events like Patrimonia, and maintains thought leadership via blog content covering overseas investment topics and regulatory updates. Leadership includes Sébastien Guillaudeux (Directeur Général) and Karim Lahlou (Business Development Manager).
