GRAVEYARDS CAN SPOOK INVESTORS. Where an industry segment has had a history of several well-known failures, most investors will run a mile, regardless of whether the failures were different from your invention. Graveyards spoil fresh markets and are very difficult to enter. It is your job to know these histories, and it is prudent to avoid them. You do not need controversy to plague your funding. This is a shame because most graveyards have untapped markets and significant opportunities.
