What FIRSH does

FIRSH is a Paris-based boutique law firm (Société d'Avocats, Selarlu) founded in 2023 by Claire Poirson, operating from a single office at 38 rue de Courcelles in the 8th arrondissement. The firm delivers legal advisory and litigation services across four tightly integrated practice areas: Intellectual Property & Media; Tech, Data & Cybersecurity; Emerging Technologies (Web 3.0, NFTs, blockchain, metaverse); and Artificial Intelligence law. It serves a cross-segment client base that includes AI startups and technology companies, creative studios and media organizations, luxury and fashion Maisons, and public institutions and professional bodies — in each case focusing on legal questions arising from innovation, digital content, and emerging technology. Both advisory (conseil) and contentious work are offered under French Bar fee rules (forfait, temps passé, honoraire de résultat), with no public pricing or subscription model.

The firm operates with a deliberately small team of around seven people — a founding partner, three named associates (Léa Monel, Samuel Brami, Marie Sirot) plus support staff — and is differentiated less by scale than by depth of specialization and an integrated research asset, FIRSH Lab, which publishes an annual White Paper (most recently on deepfakes) and convenes an International Expert Committee on technology-law issues. Distribution and demand generation are content-led: an active LinkedIn presence, a newsletter, recurring press contributions to Le Figaro, Le Point, Le Parisien, BFM TV, RTL, France Inter, TV5 Monde, Journal du Net, and RFI, and conference participation at VivaTech 2026, the European Fashion & Luxury Conference in Milan, B SMART Tech Talk, and MPACT IA forums. The firm is independently owned by its founding partner, has no external investment or parent entity, and reports no revenue publicly.

Financially, FIRSH is a private, founder-financed French SELARLU with no disclosed funding rounds, debt, or M&A activity. Revenue is not publicly reported; the firm operates under French Bar fee-fixing rules rather than any disclosed ARR or SaaS-style pricing. Its principal monetization is therefore professional fees billed under multi-year engagements, with no subscription, transactional, or platform revenue stream.
