What do MP3.com, Linspire, and SIPphone have in common? They were all created by Michael Robertson who now has another venture on the table. His latest startup is called Dealipedia. It’s a wiki that specializes in deals. Robertson wanted to fill the void on business deal data. The site includes news, merges and acquisitions, venture investments, IPO’s, bankruptcies, gossip and a plethora of other wiki goodies. Dealipedia is structured in the basic wiki format: users contribute news, articles, and facts to the site all the while building a veritable encyclopedia/database of business. Robertson recruited his friends to submit the initial fodder for the site. Unlike Wikipedia, Dealipedia submissions follow a more rigid structure with predefined fields for entry. This allows for a faster and more efficient search and advanced search. The site is still in its initial stages, but so far categories include, deals, “Who Made Money”, companies, and a hall of fame. There’s also a free weekly newsletter.
