The most important rule of building a board of directors

When trying to build a Board of Directors, or Advisory Board - you want to find people with a good network, deep market expertise and/or great knowledge of your industry.

The biggest mistake Founders make is that they like to just add names to badges. Regardless of their clout, choosing advisors only for cosmetic reasons isn't going to bring you value -  its actually going to negatively affect you more than it is going to help.
