I once on a company where a CEO did that 3 times in a row to an engineering team, and mentioned wanting that team to be 4x its current size in two years. In an interview, he mentioned The Mythical Man Month as one of his favourite books.
Everyone perceives things through their perspective. Dopey CEO guy sees himself as the surgeon leading the software “surgical” team described by Brooks.
Just like there's a bunch of politicians complaining about 1984 who clearly have never opened "1984" too.
Those hundreds of millions of VC money have to be put to use. So it either advertising or more head count.
