this might be the weirdest conversation I've ever had on this weird site.

I think the we give you stock, you give us money, we spend that money hiring is the a pretty common event.

yes very common. therefore it's highly unlikely to be what OP is asking about.

by this point, it's hard not to conclude that OriginalMrPink and I are being wilfully misunderstood here.

OP is interested in more details about the deal, particularly what power the investors might have, to ascertain for himself to what extent the investment might change the business.

Probably given a board seat, but usually the exact terms of a round are covered under NDA.

OP is very clearly able to make some guesses himself, as he does so in his comments.
