It might not always be possible to directly translate it to revenue, but in my company, we started using an RAG system to help the Customer Support team answer inquiries. It replaced the old Knowledge Base articles search system, and it improved the number of processed inquiries by about 30%. This decreased customer support times and probably helped make customers happier, which is a pretty nice win, even if it would be pretty much impossible to attribute any revenue numbers directly to it.
