Tracked.com is a sort of re-imagining of a business information service that provides personalized information on businesses and the people associated with them.
Conceived by Mike Yavonditte, formerly of Quigo, Tracked.com, of course, provides extensive information on ticker-based companies, including company financials, much like Google and Yahoo Finance do, but it's not just a stock service. Its strong point is that it also tracks privately held companies, gathering any available information on them. For all of these companies, Tracked shows a wealth of information and news as well as the people associated with the company, complete with fleshed out profiles on them as well.
This is an awesome business and competitive intelligence tool, they use massive data sets to compile all of the data they have on people and companies. Love it! I've been using it to track certain companies (i.e Twitter) and then when new or breaking news comes out via 'My Tracker' I immediately post to Twitter and that usually makes me the first to post interesting finds.
