João Fonseca, one of Brazil’s most highly rated young tennis players, has been unveiled as a brand ambassador for Claro, the Latin American telecommunications company owned by América Móvil, as the brand deepens its investment in emerging sporting talent.
The agreement brings Fonseca into Claro’s wider sports marketing ecosystem and aligns the telecom giant with a new generation of Brazilian athletes as it looks to strengthen relevance among younger, digitally native audiences through long-term ambassador partnerships.
As part of the collaboration, Fonseca will feature across Claro’s national advertising campaigns, digital platforms, and brand activations. The partnership will focus on Claro’s mobile connectivity and digital services, with the player integrated into original content, promotional appearances, and social media-led storytelling designed to follow his progression on the professional circuit.
Fonseca has rapidly established himself as one of the standout prospects in Brazilian tennis. The teenager has delivered a series of impressive performances on the ATP Challenger Tour and continues to gain exposure at senior-level tournaments, positioning himself as a key figure in Brazil’s next wave of international tennis talent.
The appointment further strengthens Claro’s footprint in tennis. The company already sponsors Brazilian player Victória Barros, holds partnerships with tournaments including the Rio Open and the São Paulo Open, and supports grassroots development through its association with Yes Tennis, where Fonseca has trained since the early stages of his career.
Beyond tennis, Claro has also expanded its presence across global sport in recent months, including a regional partnership with the BWT Alpine Formula 1 Team through Argentine driver Franco Colapinto, underlining its broader strategy of aligning with high-growth, globally relevant sporting properties.
The deal reflects a wider trend among Brazilian brands to engage athletes earlier in their professional journeys, securing long-term associations ahead of potential global breakthroughs. For Claro, the partnership offers a scalable platform that can grow alongside Fonseca’s international profile, delivering sustained visibility across domestic and global markets.
Fonseca is expected to continue competing across ATP Challenger events and selected ATP Tour tournaments as he progresses through the professional ranks, with Claro activating the partnership across multiple touchpoints as his career develops.
