[adventured]

The last A round I did a few years ago, funded by a top tier investor, had no background check. It involved basic, fairly routine, due diligence and several conversations.

I'd be surprised to hear of a background check on an A round in the US, unless it involved a particularly unusual investment size or where something very specific threw up a bad red flag. And usually if you can command a massive A round, you're already a known quantity.
