In 2016 my book "Social Selling - Influencing Buyers and Changemakers", in which we used Google research from 2014, which talked about this new global phenomenon.
There was this person in an organisation that wanted change and they were willing to spend political capital to do it. Sales training systems in the past called this person an "inside salesperson", an "angel". But this was new.
The inside salesperson wanted your system to win. The Changemaker doesn't care, which system, they want the change.
The other thing is that these people are social. They are active on social networks. They grew up with social, (that is asking questions of their network) and also have business acumen.
They are out there, you just need to find them. Or of course, be active on social too and they will find you!
According to Brian Solis, the real (often untold) stories about digital transformation are the human struggles “change agents” face as they try to modernize their organizations. There are always colleagues, managers and others who don’t get it.
