I have a buddy who works in the Silicon Valley recommend Affinity CRM as he uses it to get warm introductions both personally and professionally. From what I have read it uses your LinkedIn network and "connects the nodes" in order to target potential prospects. It is expensive at $1500 a year but potentially could be useful if potential business owners/brokers have a LinkedIn. Does anyone have any experience using it in the SearchFund community?

Disclaimer: I have tried and will probably go with Hubspot, Pipedrive, or Copper, but I was more curious than anything if searchers have used the tool in a current or former life.
