MOSAIK

What MOSAIK does

MOSAIK is a boutique business law firm structured as an AARPI (Association d'avocats à responsabilité professionnelle individuelle), founded on March 30, 2022, with co-founders Pascal-André Gérinier, Julie Aubin, and William Mak. The firm operates across three jurisdictions, headquartered in Paris with additional offices in Mexico City and Hong Kong, and employs approximately 12 people. It serves a client base ranging from small and medium-sized enterprises to listed companies, with named clients spanning BlackRock, Binance, AKORIS Finance, ESSEC Business School, and SAINT JAMES.

The firm offers a multi-disciplinary practice organized around five practice areas: Commerce, Creation/Entertainment, International Affairs, Digital, and Real Estate. Its value proposition centers on a multicultural, multilingual team providing cross-border coverage through a single dedicated point of contact, addressing the coordination gap faced by SMEs and mid-cap clients operating across French, Latin American, and Greater China jurisdictions. The firm has invested in memberships across bilateral chambers of commerce and business associations (CEMF, CCI France Mexico, France Hong Kong Business Association, Franco-Chinese Footwear Association) to source cross-border mandates.

MOSAIK's business model is fee-based legal services revenue from hourly billing and project engagements typical of boutique law firms. The firm has pursued an entirely organic growth strategy with no disclosed funding rounds, growing through targeted lateral hires (including Izzat-Begum RAJAN in January 2025 and Pénélope Ghiglia in July 2025) and network-driven client development. There is no public revenue disclosure and no evidence of technology-platform or productized service extensions beyond traditional legal advisory.
