There is a little known history about how to acquire FREE contacts (legitmately) via SalesForce. They acquired a company called Jigsaw.com
about 6 or 7 years ago. Jigsaw was an open-sourced FREE platform that allowed garbage in, garbage out contact uploads that were vetted and edited by whomever had an account with Jigsaw. Well, when Jigsaw got bought out, SalesForce decided that they were going to charge for this free service, which they still do today. However, the "deposit contacts to download contacts" approach is still there, but they've buried this truth deep in many clicks. Nonetheless, connect.data.com/home
is the URL. I happen to have the top level connectivity and can pretty much get thousands of names whenever I want that happen to have about an 80% legitimacy rate. If anyone is interested in partnering with me to get the info they need feel free to chat with me instantly at twoople.com/spark
It seems SalesForce values my level of access (or partnership with you) as worth over $1,500/year. http://www.data.com/connect/pricing.jsp.
