In 2017 Joe shut down six physical call centers in Grand Rapids, Michigan, and swore he was done with that business for good.
He wasn't. Today his companies own the dialer, texting, and email software that runs it. He just traded the buildings for the code. That's the pattern behind almost everything he's built: he hits a problem, can't find a tool that actually solves it, so he builds his own and runs his own businesses on it before anyone else ever touches it.
He writes and speaks about the work too. His book, The 60/20 Relationship Rule, is on Amazon. He speaks at conferences and company events, and he keeps his articles and working notes in one place.
