A experiência e a participação em processos de repercussão nacional e internacional levaram o GNA a conquistar, logo após a sua fundação em 2009, o reconhecimento de seus clientes, do mercado, dos seus pares e das principais entidades certificadoras do mundo, como a Chambers, o Which Lawyer e o Expert Guides, que recomendaram o GNA como escritório brasileiro especializado em Competition and Antitrust.

Pela segunda vez consecutiva, o GNA figura como LEADING FIRM no conceituado ranking da revista Chambers que, na sua última edição (2012), divulgou a seguinte análise sobre o escritório:

"This boutique is consolidating its presence in the market and expanding in terms of both infrastructure and clients. The firm is primarily focused on defending clients affected by anti-competitive behaviour investigations. Recently, the practice has sought to diversify and has increased its volume of cross-border notifications and preventative consultancy work. "The quality of service at this firm is excellent. The lawyers are real experts, consistently diligent and prompt to respond," explain clients, which include giants such as the Votorantim Group, Kodak and Usiminas. According to sources, Gianni Nunes de Araújo has "impeccable technical skills" and is also "a sharp strategist who perfectly understands the challenges faced by a multinational and knows how to achieve the best possible results."
