The tool I most often use with WINMO and love is the Advanced Search, where I go directly to any company I choose and get contact information for their C-Level executives and decision-makers along with information about their media spend broken down by year and type of media. It also shows me what agencies they use so I know who my competition is. Review collected by and hosted on G2.com.
I don't think there is a downside to using WINMO. Review collected by and hosted on G2.com.
