I worked at a place where we developed information extraction systems that could be customized to the needs of particular customers. This was before transformers so the technology wasn't 100% ready.

Think of a global aircraft manufacturer turning maintenance documentation into a knowledge graph, a global clothing and shoes retailer building a model of what social media thinks about them, etc. I told other employees that our product could generate enough value for one customer that it would be worth it for one to buy us and... that's what happened.
