Marsia

What Marsia does

Marsia is a Paris-based residential real estate agency operating as a SARL (MARSIA SARL, RCS Paris 843 573 544) from 178 rue de Tolbiac in the 13th arrondissement. Founded approximately ten years ago by co-founders Martin Delpuech and Anastasia Blinov — both former lawyers who transitioned from legal careers into real estate — the firm provides residential property sales, free property valuations, and apartment rental services across Paris arrondissements 1-20 and multiple Île-de-France suburbs including Boulogne-Billancourt, Sceaux, Montreuil, and Levallois-Perret. The agency employs 1-10 people and holds professional card CPI 7501 2021 000 000 799 issued by CCI de Paris Île-de-France, with SNPI (Syndicat National des Professionnels Immobiliers) professional membership.

The firm's service portfolio consists of four core offerings organized as a traditional boutique agency model: Property Acquisition Services (Acheter), Property Valuation Services (Estimer), Property Rental Services (Louer), and Sales Commission Services (Vente). The technology stack is non-proprietary, relying on standard agency operations, a WordPress-based website (marsia.fr), organic social media presence on Instagram and LinkedIn, and direct client engagement. There is no app, no API, and no AI/ML components. The agency positions itself on founder expertise and trilingual capability (French, English, Russian) to serve expatriate and international clientele.

Marsia's revenue model is purely transactional and commission-based. Sales commissions range from 5% to 6% TTC depending on price bracket (5% for properties above €500,000; 6% for properties between €200,000 and €500,000; fixed fee for properties under €200,000), charged to the buyer and negotiable. Rental fees follow French regulatory structures: under the 1989 law, landlords pay one month's rent and tenants pay €15/m²; for non-regulated bails, both parties pay one month's rent. Property valuation is offered free as a lead-generation tool. No funding rounds, no external investors, and no revenue disclosures exist; share capital is €1, consistent with a small partnership structure.
