The site is bidboxr.com We're getting ready to launch and since I've enjoyed so many of the articles posted here I thought it would be great to get some feedback from the YC community. Bidboxr.com is a unique blend of online advertising and online auctions. Instead of simply providing a site where sellers list items and bidders bid on those items, we've created an interactive ad banner that bring auctions to the bidders. One of our major goals when we created bidboxr.com was to provide online entrepreneurs/startups with a profitable source of revenue. Think of it like Google's adwords/adsense model, but we're using interactive auctions instead of static ads. The auctions are relevant to the content of the page, so it's designed to draw users who are interested in that particular content. Imagine reading a blog post about a digital camera and looking at an ad on the side of the page showing an image of the exact same camera on sale and closing in 10 minutes for $50 with a big 'BID NOW' button beneath it. If you're interested in running an ad on your site simply sign up, add a few lines of code and when someone bids from your site you earn money. I've started to do a few "pre-launch" marketing tests to see which method would bring in the most users - so we've already started to see some sellers listing items. If you have anything you'd like to list or know anyone who might want to list some items - I'll remove all listing fees from anyone that list anything over the next few days. Thanx!
