How can I use this to find net new companies?

You can access the networks of any of your connections on CTD, not just people in your company. Therefore you can tap into the networks of friends, former colleagues, and mentors outside of your company to find "ins" at new companies to sell to (image we use for this should probably have more connectors). 

Connect the Dots also allows you to search for a company or browse connections' networks to find a company of interest. 

Either way you do it, you'll find that you can use your network to find new companies to sell to.
