Sure, go to each country and check what food delivery companies operate in them, get a list of companies operating in the market that are not controlled by the big 5 mentioned in the article.

In Europe there were a few companies operating in the sector which were taken over by these global companies. I recall the Glovo takeover by Delivery Hero. You mention Foodpanda but you seem to be unaware this is a brand from Delivery Hero, and Just Eat is a Prosus company too.

> What countries have both the talent to build a food delivery app and the USA is the dominant player?

I'm baffled by your comment. Do you believe only the US has "the talent" to put together a food delivery business? Because even if you ignore the fact that 2 out of the 5 dominant players are not US companies, you need to be way out of touch with the reality of both the technology side and business side.
