I did this as a side project to track the most valuable/best startups. Now tracking 49 companies with a valuation of $1B+ - I predict there will be 100 1B+ startups by the end of 2014.<p>I built it mostly because I wanted to search jobs at just the best companies, so you can do that too: www.thestartup100.com/job<p>If you have comments on the site or companies on the list you can tweet them to me @thestartup100 or email frank(at)thestartup100.com. You can also sign up to add or edit companies.<p>Thanks!
