Silveiro Advogados

What Silveiro Advogados does

Silveiro Advogados is a full-service Brazilian law firm founded in 1956, headquartered in Porto Alegre, with additional offices in São Paulo and Brasília. The firm operates across core practice areas including tax litigation (contencioso tributário), corporate/M&A, private equity, environmental law, data protection (LGPD), digital assets, ESG, and broader strategic advocacy. Its primary client segment is corporate and institutional clients requiring coordinated, multidisciplinary legal advisory across regulatory, transactional, and contentious matters.

The firm's technology footprint is modest and practitioner-facing rather than product-facing. It maintains a proprietary digital platform, GFSO (Gestão Full Service de Ofícios), for managing Full Service office communications, and publishes a content-focused AI Hub covering artificial intelligence regulation. It also operates an internal training program, the Escola da Advocacia (Eajcs), a documented Code of Ethics, and dedicated ESG sub-pages under Environment, Social, and Governance. Marketing channels consist of the firm website, LinkedIn, Facebook, Instagram, and downloadable White Papers covering tax reform, LGPD, Marco Civil da Internet, Marco Legal de Criptoativos, and succession planning.

Silveiro Advogados is a private, partnership-style firm with no parent company, no external investors, and no disclosed funding rounds. Revenue is not publicly disclosed. In 2024 the firm executed three targeted lateral hires (João Crepaldi for M&A/private equity, Solange Cunha for environmental, Vanessa Cecconello for tax litigation) that deepened its specialty practices. Operationally the firm is LGPD/GDPR compliant with a designated Data Protection Officer (Maurício Brum Esteves). The business model is traditional fee-for-service legal advisory priced by matter complexity, with no disclosed public pricing.
