What Martinelli Advogados does

Martinelli Advogados (legal name Martinelli Advocacia Empresarial) is a Brazilian full-service corporate law firm founded in 1997 and headquartered in Joinville, Santa Catarina. Registered with OAB-SC under n° 252/97 (CNPJ 01.650.515/0001-08), the firm operates 16 offices across 8 Brazilian states plus the Federal District and is led by CEO Juliana Martinelli, with founder João Joaquim Martinelli as founding partner. The firm runs 20+ practice areas — Tax, Labor and Social Security, M&A, Compliance, ESG, Dispute Resolution, Capital Markets, International, Estate and Succession, Tax Incentives for Innovation (Lei do Bem), and Debt Collection — and is particularly recognized for precedent-setting tax litigation (notably PIS/Cofins and ICMS disputes cited as "Caso Martinelli") and superior-court work from its Brasília office.

The business is a traditional professional services partnership. Revenue comes from engagement-based and retainer fees negotiated per mandate with corporate and enterprise clients; pricing is not publicly disclosed and the firm provides no rate cards or subscription offerings. Go-to-market is sales-led and relationship-driven, leveraging physical office proximity, regulatory thought leadership (website updates, monthly "Informativo Brasília" newsletter), active social media presence, industry events, and an international legal alliance spanning 126 countries with 29,000+ professionals for cross-border referrals. The firm operates no proprietary technology platform; infrastructure rests on standard legal research and document management, with LGPD-compliant data handling overseen by a named Data Protection Officer (Stefanie Rosso Sarnick).

Customer concentration sits in agribusiness and cooperatives (a flagship vertical evidenced by the Somos Coop seal and Cocamar Cooperativa Agroindustrial mandate), banking and financial services, oil and gas/energy, manufacturing/automotive, technology and innovation (including Lei do Bem structuring), and multinational groups with Brazilian operations requiring Pillar Two/QDMTT advisory. The firm is Brazilian "Highly Recommended" per Latin Lawyer 250, ranked by Chambers Global and Chambers Brazil, IFLR 1000, Leaders League, ITR World Tax and ITR World Transfer Pricing, Best Lawyers, LACCA Approved, and Análise Advocacia (Most Admired since the inaugural edition), and is Great Place to Work certified. Operationally, the firm added 11 partners in the first half of 2026 (reaching 135 partners by June), pulling talent from PwC, EY, Eli Lilly, Gerdau, SiqueiraCastro, Leite Tosto e Barros, David Rechulski, Prolik, and Cursino — an aggressive lateral-hiring cadence that signals capacity build-out ahead of Brazil's tax reform cycle.
