Whatsapp is pretty much the cornerstone of personal and business relationships here in India. I’ve closed more deals over Whatsapp than over phone calls and emails and Zoom calls combined.
It is not just people talking to each other, several business rely almost completely in WhatsApp around here.
IG is also still the top social media as well globally.
Banks that use WhatsApp for customer support, or restaurant chains that take orders via WhastsApp bots, pay WhatsApp partners for API access.
The payment goes to the WhatsApp partner. What I'm not sure is, if it is distributed between Meta and the WhatsApp Api provider.
I reckon its a bit like email. Great as a top of the funnel customer acquisition tool. Not that great from a money making perspective.
