CaptShady is encouraging folks to disclose their ideas on this forum. Here's one of mine (at the risk that someone will steal it and make a billion dollars off it).
The idea involves a cross between a group funding site and a post card promotional mailing site ( sorta like
http://www.fundable.org/ and
http://www.royalmail.com/portal/rm ).
The site will be a place for businesses to meet and co-op with each other in order to share the expenses of marketing and promoting their businesses.
This would not necessarily be limited to postcards. For instance, the partners will be able to buy into a website, flyers, newspaper ads, radio spots, anything that single businesses can do now but with a group of marketing/advertising partners.
The co-op user will be able to choose from different variables like non-competitors, proximity of partners, mode of campaignes, industries . . .
The user will also be able to set variables that determine when or whether a particular campaigne gets triggered and executed. For instance, one of the triggers could be a certain price, which in turn may be based upon reaching a certain amount of co-op partners.
Another application of such a site will be in lowering the costs for otherwise unequal campaingnes. For example, a real estate agent only wishes to send flyers to neighborhood A but a pizza place wishes to cover neighborhoods A and B. By co-opting, the two can save money and still reach their targets.
There you have it!
