I wouldn't worry so much about WhatsApp suing you. If they don't like what you're doing (or others for that matter) they can more just change their protocol.

The problem with building a company around such a solution rather is this: Is there a market? Sure, having a machine automatically answer customer requests is a nice parlour trick but what's the benefit for the customer?

Just saving money on call centre agents? Or does the software actually solve a real problem in a novel way that can't be tackled using existing solutions?

I don't think whatsapp will change their protocol too much, as they'll break millions of clients installed in old phones.

The benefit for the company looks obvious to me: save money on call centre / community management. Deliver a service to millions of mobile users without requiring them to download your app (just adding a phone number to the agenda).

The benefit for the end-user: having a conversational interface with a system is probably the lowest barrier entry to that system for a human. Everybody knows how to chat using whatsapp, but not everybody knows (nor is willing to learn) how to use your "user-friendly" GUI.
