Ampere.Ginisty

What Ampere.Ginisty does

Ampere.Ginisty is a Paris-based French notary firm (étude notariale) headquartered at 90 Rue de Miromesnil in the 8th arrondissement. It was formed through the 2023 merger of two historic Parisian studies, Ampère Notaires and Ginisty & Associés, whose lineage extends back to 1757 and 1611 respectively. The firm is organized around five practice areas: institutional and tertiary real estate (acquisitions, arbitrages, and complex transactions across retail, offices, hotels, healthcare, logistics, and industrial assets); real estate development (administrative guidance for promoteurs); financing (structuring of mortgage loans, crédit-bail, and fiducies for banks and investors); family, wealth, and residential real estate (successions, donations, matrimonial regimes, and residential transactions); and energy (photovoltaic installations and renewable energy integration into real estate). It serves a diversified client base spanning CAC 40 corporates, premier-rang banks, institutional investors, property developers, local SMEs, and private individuals.

The firm operates with approximately 22 staff, including seven notary partners (associés) and supporting notaires, juristes, an office manager, a responsable formaliste, a responsable comptable, and notary trainees. Its technology stack is deliberately lean and externally sourced: an electronic dataroom via Espace Notarial for per-transaction document exchange with clients and external advisors, and SystemPay for online client payments. There is no proprietary platform, no in-house software products, and no disclosed AI capabilities. Quality is anchored by ISO 9001 certification covering notarial services.

The business model is built on France's regulated notarial tariff (Décret n° 2016-230), with revenue from proportional fees (émoluments proportionnels) scaling to transaction value and fixed fees (émoluments fixes) for standardized acts. The firm voluntarily discounts its share of proportional fees on high-value transactions — 40% for Dutreil transmissions above €15M, 20% for residential sales above €40M, and tiered 10-20% discounts for non-residential property sales between €40M-€60M and above €60M. Distribution is single-channel through the Paris office and direct, relationship-led client engagement; marketing relies primarily on the firm website and search engine visibility rather than outbound sales or paid acquisition.
