Gay Lussac Gestion

What Gay Lussac Gestion does

Gay-Lussac Gestion is an independent French portfolio management company founded in 1995 and headquartered at 45 avenue George V in Paris, with a secondary office in Brussels. The firm operates under AMF license GP 95-001 and is structured as a privately-held SAS, providing asset management, employee savings and retirement solutions, and private wealth management to wealth management advisors (CGP), family offices, companies, institutional investors, and individual clients in France and Belgium.

The product portfolio spans equity funds (Gay-Lussac Microcaps, Microcaps Europe, Microcaps Monde, Smallcaps, Green Impact), diversified funds (Europe Flex, Héritage Sélection Crédit, MacroSphere Global Fund, MacroSphere Low Vol), employee savings vehicles (Gay-Lussac Trésorerie, Microcaps Épargne, Impact Social), and the digital InfiniPER individual retirement plan. Investments are managed through a proprietary four-stage process: quantitative screening on Low Volatility/Low Beta/Momentum criteria, quarterly macroeconomic committee review chaired by economist Jean-Pierre Petit, fundamental stock analysis reducing the universe from 200 to 50-60 holdings, and ongoing portfolio construction.

The business model is fee-based on assets under management across subscription/recurring revenue streams, with a sales-led go-to-market targeting CGPs and private banks, supplemented by direct digital distribution for the InfiniPER product. The firm differentiates through 30+ years of microcap specialization, an open-architecture distribution model, and increasing ESG integration via SFDR Article 8/9 classifications and pursuit of Label ISR and FAIR Finansol certifications on the employee savings range.
