Perplexity has struck a global partnership with Cristiano Ronaldo, with the footballing icon taking a strategic investment stake in the AI answer-engine company.

The California-based firm says Ronaldo uses the product as part of his preparation and decision-making, and the collaboration will help push the platform to a wider mainstream audience.

To launch the tie-up, Perplexity is rolling out a dedicated Cristiano Ronaldo hub featuring an interactive CR7 experience, including career timelines, curated questions and exclusive imagery for fans to explore.
