When a VC says "no, sorry", she usually means it. Arguing and repeating your viewpoint over and over is not going to change her mind. 

  • She heard the point before, thought about it, and did not find it convincing enough
  • You now come across as a nagging CEO, might be difficult to work with
  • You are arguing about a point that she says was the reason she turned you down, but the real reason might have been something else ("I simply don't like you") which she is not sharing with you.

What you can do is inject new information into the conversation. A new customer signed up. A similar company got funding. A new team member came on board. A new way to slice the customer data gives a new insight. Chances that it will work are low though.
