"The Spark of Genius Series highlights a unique feature of startups and is made possible by Microsoft BizSpark. If you would like to have your startup considered for inclusion, please see the details here.\nName: Keepio\nQuick Pitch: Keepio helps you keep track of collections and sell belongings within your social graph.\nGenius Idea: Sometime in June, college seniors' Facebook news feeds start to look a lot like Craigslist. As recent graduates move out of apartments, they turn to their social networks to unload used furniture, posters and other items.\nWhy not just use eBay, Amazon, or Craigslist? Well, eBay and Amazon charge a transaction fee and shipping costs. Craiglist usually requires a face-to-face interaction with a stranger. It's just easier to sell stuff to people who you already know.\nKeepio runs with this concept. The transaction platform makes it easy for anyone to post items for sale on Facebook, Twitter and within your own Keepio network. You decide if you want to make each of your listings private, public or kept between your Keepio friends. People who land on your Keepio page can browse all of your publicly listed items.\nThe site also wants to help manage belongings that you don't intend to sell. Posting a comic collection or art collection could help organize it, and users can share their collections with fellow enthusiasts. Groups on the site make it easy to browse collections belonging to people with similar interests and purchase used items.\nThis concept is somewhat similar to the way Snooth helps wine enthusiasts catalog and share their collections, what Listal does for media collections, and WhatUCollect does for all collections. Keepio, by contrast, hopes to appeal to enthusiasts of all kinds, whether their passions require camping gear, scuba diving equipment or a garden that produces a surplus of vegetables.  \nInstead of charging a transaction fee, Keepio's revenue will come from learning what its users are interested in and presenting targeted messaging based on that information. For instance, advertisers could send an extended warranty to someone they know previously purchased their products.\nThe startup is still bootstrapping for now, but it has acquired a broad base of users (if not a particularly deep one) in 16 different countries since launching in 2010. \n\n\n\n\nImage courtesy of iStockphoto, thesuperph.\nSeries Supported by Microsoft BizSpark\nThe Spark of Genius Series highlights a unique feature of startups and is made possible by Microsoft BizSpark, a startup program that gives you three-year access to the latest Microsoft development tools, as well as connecting you to a nationwide network of investors and incubators.
