Social calling math

In my last post I went through the math on traditional cold calling.
There’s an alternative way to get meetings with prospective clients, but sales people don’t generally use it. Oddly enough they often do use it when they need a job and in this case they call it “networking”. I had to come up with a cool name for using networking in sales so I call it “social calling”.
Whatever you call it, I think the math on the effectiveness of a networking approach vs. a cold calling approach is pretty interesting…

He figured out that we have about 150 relationships we can maintain (this number should be higher for sales people and entrepreneurs involved in developing their business.)
If you know 150 people and each of your connections
