I want you to watch this episode of Wine Library TV.
Gary V. talks with the guys from Three Thieves. The 20 minutes or so is not about tasting wine, but rather how these three built their business.
Their company name comes from the fact the guys buys excess, premium wine from wine producers, create their own blends, and sell most of their wines for under $10. These three have been particularly innovative in their packaging and marketing.
The Newspaper Club in the UK founded their business on a similar excess. After developing a short run newsprint project, the founders discovered that most newspaper production facilities go unused during the day while the day's paper is being put together. Again, excess capacity creates a business model.
Every industry has their version of excess whether it is a machine waiting to be used or product that never found a customer. Is there an opportunity waiting there for you?
