What is a term for the person whose involvement in your startup can improve your pre-money valuatuon for your first negotiations with VCs & angels?
Otherwise — DO NOT DO THIS.
You can have invisible advisors, that’s OK. But 96/100, don’t have someone visibly involved in negotiating valuation at least until you are in the $X00m phase. It will be a clear turn-off to VCs, for many reasons.
