I had this same question. Also, are "developers all over the world" "happily using Zero Sheets"?

Based on OPs description, I wonder if this company was spun up while already doing business with those companies.

There are far more startups/products using that tagline of "used by developers all over the world"/"used by $x company" than our industry seems to want to admit.
