In an effort to improve our searcher and therefor the prospecting abilities of our users, Amplemarket has added a 'Past Companies' filter. This filter will allow you to search for leads who previously worked at other companies, which allows you to execute more sophisticated sales plays.
Example: You could combine the use of filters such as 'recently job changes' and the 'past company' filters to identify a lead who previously worked at a company that is a customer of yours. This will, potentially, garner a new customer as this lead is already familiar with your product and may want to implement it at their new company.
If you would like any more information on the Past Companies filter or if you have any questions, please reach out to support@Amplemarket.com
