Note that in the EU and UK mid-size has a definition:
"fewer than 250 employees and a turnover of under €50 million (or a balance sheet total below €43 million)"
Thus by definition that company wouldn't be mid-sized over here anyway.
edit: in-fact after checking even in the US, the IRS for example declares a large business as one with more than 10 million in assets, though there is no set rule like in the EU to be used by other gov orgs.
I'm with a rather small company (~ 250 people) in the US and we pay about $1,2mm-1,4mm yearly on GCP alone.
