My guess based on the investors (Capital Appreciation owing 35% in GovChat. Capital appreciation also been Fintech / Payment and Payment Infrastructure business) is that GovChat was hoping to using WhatsApp APIs in a way that would allow financial services sold/distributed on/through WhatsApp...
"The Competition Tribunal asked GovChat what its business model is given that it offers its services for free to government. GovChat declined to answer the question in a public forum."
Yeah GovChat is 100% legit, but it can't talk about how it makes money.
