I've identified a veteran CTO of several successful web and tech companies who I'd like to be the first Advisor to my web-based startup. He could help me with operations, as well as business strategy. He has had extensive experience as an advisor to other startups.
From reading other responses on this site, it's not clear to me what kind of equity I should offer him. One response said 0.1% for about 10 hrs of phone calls per quarter. Is this the minimum? What's a reasonable max, and is there an average? And, what are the negotiation points?
