Our history

Learn more about our history, which started for than 10 years ago and inspires us for a present and a future full of opportunities.


The foundation of Briganti Advogados was inspired by the strong presence of Spanish clients and their operations among Leonardo’s clients’ portfolios. The new firm soon became a renowned business hub for companies and investors in Spain and Brazil. Our founding partner and Tax expert Leonardo Briganti, who led this initiative, accumulated significant legal experience since 1998. When he founded Briganti, Leonardo already had in mind the future internationalization of the firm.


Partner Alexandre Fragoso Silvestre joins our law firm, enabling greater and more qualified performance in our team in consulting and litigation focused on companies. Silvestre holds a master’s degree in Labor Law from PUC-SP and has accumulated broad experience in this field since 1999.


We start the BriganTI legal hub aimed at supporting promising businesses and startups. Using this platform, entrepreneurs can apply for an initial consulting session which covers everything they need to structure their business, and they pay for these services only when their businesses start to thrive.


Our team of partners expands again with the arrival of Francisco Roberto da Silva Jr., who brings to Briganti Advogados his expertise in Civil Law, with a focus on contracts, consulting, litigation, administrative disputes, and arbitration – fields in which he has been working since 2004.

In this initiative, we aimed to merge Briganti Advogados’ expertise and domains with the extensive experience of the lawyer Rodrigo Loureiro in the implementation and management of International Desks in Law Firms with a global presence. Resident in Paris since 2012, Rodrigo Loureiro is also the partner responsible for implementing the firm’s international strategy and co-chair of the French-Brazilian commission of the Paris Bar Association.


Our founding partner, Leonardo Briganti, becomes an advisor to the recently opened Pateo 76 – a space dedicated to connecting and driving new businesses and startups in São Paulo.

Imagem Compromisso Social

Social commitment

In addition to our business activity, we are aware of the importance of the legal community’s contribution to a more just society. Based on this assumption, we also act on a pro bono basis, that is, without charging attorney’s fees, defending the interests of individuals in economic and/or social vulnerability.
