I'm not sure if I understand the point of this blog post. VCs give money to startups so these startups can grow faster than they would without external investment. So they will spend that money. It is not like startup come to VC and said: I need $10M and I will put that money in the bank. Maybe the blog should be how it is important that startups are more focused when they spent? Or maybe how VCs are investing into companies with not so great ideas? I'm just confused here.
