Be careful -- that is a common(?) way for VCs to also say no -- "come back when you have 10 clients" which next time becomes "come back when you have 50 clients" and it goes on forever. Not saying that is the case here, but, don't put all your eggs in one basket that you will be ready to raise when you have 10 clients.
