Lucas lives in São Paulo and will be the first to tell you that in Brazil, WhatsApp is not just an app — it's basically how the country runs.

He covers everything from local business networks and community trade groups to football discussions, regional cultural exchanges, and neighbourhood support chats. His listings tend to have real energy to them because that's just how Brazilians use these spaces.
