Castaldi Partners

What Castaldi Partners does

CastaldiPartners is an international law firm founded in 1997 (originally as Castaldi Mourre & Partners, rebranded around 2017) that specialises in cross-border legal matters between France and Italy. Its service portfolio is organised around five core practice areas: corporate M&A and restructuring, international arbitration and dispute resolution, employment and labour law, real estate and retail, and intellectual property (delivered through the IP Alliance with Kern & Weyl). Named clients include Eni, Salvatore Ferragamo, Marelli, OVHcloud, Apave, MicroPort CRM, Stef Group, ProductLife Group, Diesel, Boggi Milano, René Caovilla, Conserve Italia, Club Med Italia, and ICOP, spanning energy, luxury/fashion, industrial, technology, healthcare, logistics, and infrastructure sectors.

The firm operates owned offices in Paris and Milan and extends its reach through three branded alliances: the Buckles CastaldiPartners Alliance (UK), the Labour Alliance with de Berardinis e Mozzi, and the IP Alliance with Kern & Weyl. In March 2024 the firm converted from a Professional Association to a Società tra Avvocati and adopted Benefit company status, formalising ESG commitments that had earlier been recognised by the 2021 LegalCommunity Sustainability Awards. The partnership is private and partner-owned, with 15 named partners and a workforce in which women represent over 60% of staff and 50% of the partnership.

CastaldiPartners generates revenue through professional services fees billed on a per-engagement basis to corporate clients, with no public pricing or subscription model. Go-to-market is partner-led, leveraging referral networks, chambers of commerce (CCI France Italie, BCCI), industry events (Legalcommunity, Le Fonti awards, the Incontri di Via Savona series, France Odeon), and direct enterprise relationships rather than intermediaries. The firm's primary segments are large multinational and domestic corporations engaged in Franco-Italian transactions, dispute resolution clients, employment-law clients, and luxury/fashion brands expanding across the two markets.
