A little offtopic here. I actually was thinking of creating a messaging app (serious) It is quite easy to build the app for any company or individual in India . India's own messenger will quite be popularised. But the catch lies afterwards. Handling the data. Setting up data centers in India is not simple. Renting a space or using AWS or Google Cloud is not ideal for Data privacy. And financing in a way is another hell of a job . where it does not collect data and then showing random ads in a way that it does not hinder the messaging experience for anyone . That is why Whatsapp still rules in India(they collect data but do not show ads)
Brazil and India are the top users of Whatsapp . Many people in USA still use text messaging through their carriers
Do share some innovative finance models if you have
can't get myself to use any product from that company when their founder is a hard core sanghi. zoho does have some well priced product. almost got tempted to use their email service few months ago. but sticking to keeping them in my blocklist.
