WhatsApp has stopped being just a chat app and has become the main digital counter for Brazilian SMEs. The numbers help understand the size of this opportunity and what to do with it. We gathered the most relevant data and what they mean in practice.
Reach is almost total
Statista estimates point to about 147 million WhatsApp users in Brazil, equivalent to practically the entire internet‑connected population, which makes the country the second largest market for the app in the world, behind only India. For an SME, this means the channel where the customer already is is WhatsApp, not an app they would need to download.
Daily use is intense
A 2025 Opinion Box survey indicates that about 97% of Brazilians open WhatsApp at least once a day and 61% several times a day. A channel with this frequency of access responds faster than email or phone, and it is where a message has the highest chance of being seen instantly.
Consumers want to talk to companies there
A BCG study in partnership with Meta, with more than 400 Brazilian companies, showed that 8 out of 10 consumers prefer to communicate with companies via messaging. Add to that the fact that most users have already interacted with brands and have chatted with a bot through the app: the customer not only accepts it, they expect to be served on WhatsApp.
The opportunity for the SME
About 5 million SMEs already use WhatsApp Business in Brazil. The competitive differentiator today is not being on the channel, but serving well and quickly on it. That’s where AI comes in: an agent that replies instantly, 24 hours a day, turning message volume into sales instead of leaving money on the table.
