What GOSSET does
GOSSET Conception SARL, trading as Gosset Patrimoine, is a Lille-based turnkey rental investment firm founded on 14 February 2017 by sisters Marie Gosset and Claire Gosset. The company serves individual property investors in the Lille metropolitan area with an end-to-end service that combines property sourcing, full-scale renovation, complete furnishing, and ongoing rental management. Since founding, Gosset reports completion of more than 200 projects and currently manages over 150 rental lots across Lille, Lambersart, La Madeleine, Marcq-en-Barœul, Bondues, Wasquehal, and surrounding municipalities.
The service portfolio centers on the "Projet Clé en Main" turnkey product, complemented by the "Signature Gosset" renovation-only offering for existing owners, the "Club Pépites" private network for off-market deal flow, and modular services covering wealth strategy consulting (including LMNP, déficit foncier, and SARL structures), property search, project sketches delivered within 72 hours, 3D design and furniture (including four in-house furniture collections developed by Claire Gosset), and ongoing rental management. All client-facing functions are internalized — there is no subcontracting of project execution — with an external network of vetted artisans supporting construction.
Gosset operates a high-touch, consultative sales model targeting individual high-net-worth investors, with investment envelopes ranging from under €150,000 to over €600,000 per project. Revenue is generated through professional service fees on turnkey and renovation engagements (multi-year contracts) plus recurring monthly subscription fees on the managed rental portfolio. The company is privately held by its two co-founders with €12,000 of share capital, operates from a single office at 56 Avenue Henri Delecaux in Lambersart ("La Maison Gosset"), and employs 11–50 staff. The firm is bootstrapped, with no evidence of institutional funding, parent company ownership, or external investment.

GOSSET competitors and assessment
Company assessmentBroad incumbents
- Orpi: Largest French cooperative real estate network covering transactions, rental management, and related services. Competes with Gosset's sourcing and management functions but does not offer integrated renovation and investment structuring under a single accountable team.
- Citya: Major French property management and real estate transaction network with deep regional roots, including northern France. Competes with Gosset on the rental management side but lacks the integrated investment advisory and renovation offering.
- Sergic: French property manager with strong presence in northern France (headquartered in Hauts-de-France), offering rental management, transactions, and syndic. Geographic overlap with Gosset's home market, though broader and less specialized on turnkey investment.
- Square Habitat: Real estate arm of Crédit Agricole offering transactions, rental management, and advisory. Comparable on the rental management and investor advisory axis, but distributed through banking branches rather than a specialist boutique model.
- Foncia: France's largest residential property management group, managing hundreds of thousands of lots nationwide. Overlaps with Gosset's rental management arm and investor servicing, but operates as a broad incumbent across all property types and geographies rather than a specialized investment-focused offering.
- Nexity: Integrated French real estate group covering development, rental management, and investor advisory. Competes broadly for the same investor persona but operates at significantly larger scale with a different capital and developer-led structure.
- Laforêt: National French real estate franchise specializing in transactions, rental management, and property management. Overlaps with Gosset on investor-side brokerage and ongoing management but is franchise-driven and lacks the renovation integration.
- IAD France: France's leading network of independent real estate agents, with growing presence in property management. Comparable to Gosset on the brokerage and investor-acquisition side, but relies on independent contractors rather than an integrated team.
Direct peers
- Masteos: French proptech offering turnkey rental investment with property sourcing, renovation, furnishing, and management under one roof—the closest direct analogue to Gosset's integrated model, but operating at national scale across multiple French cities.
- Mandat Gestion: France-wide rental property management specialist focused on long-term residential rentals, including furnished (LMNP) and traditional leases. Directly comparable to Gosset's ongoing management line of business, though without the integrated renovation and investment advisory stack.
