Jack, look at this thread viewtopic.php?p=27627
already answering a number of questions about the site.
Here is just a portion of what is posted there.
I looked at your site and it is basically the same as other sites doing the same thing. You are not the only one doing this. The web is flooded with websites all claiming to be the place every Inventor should list their idea/product to get noticed, funding, sales. They all say list with us for free and companies and investors will find your product.
You say yours is an international marketplace. If they are on the internet they are all international marketplaces. There is nothing special to being international anymore. You get international exposure just by being on the internet. I get contacted by people all across the world that find my site using Google.com. I didn't do anything special that makes me stand out over the next website or buy a spot on Yahoo or Google so I show up first in a web search.
My problem with these types of websites is that they don't work unless the website has direct contact to every possible industry worldwide, which they don't. The Inventor that has a patented tool and posts it on your website or any of the others has no better chance of getting noticed by Black and Decker than if they made their own website. Large companies do not daily search the web looking for invention posting websites and then look through each and every posting on that website looking for the next big idea. They would have to employ a staff just to do the daily searches. So, what would bring all these companies/investors to your site daily over the other hundred websites offering the same setup?
Most large companies have a system set up to either review ideas submitted or go through a broker to filter the products they see. They also do their own product searches or they don't look at any ideas at all and hope they can come with new products in house through their own research and development department.
Posting sites feed off the hope of the Inventor that they will be spotted by a large company and make millions. They are better served to contact the company they want to attract themselves than post on a site and hope someone notices them.
