I didn’t think Parker Conrad would get up off the mat when he got ousted from his previous startup, Zenefits. No one in Silicon Valley did. Instead, Parker let his rage propel him into an all-consuming mission to prove the haters wrong and build Rippling, a $17 billion juggernaut that blows his prior success out of the water. Parker has advice for founders: from productively harnessing the chip on your shoulder, to maintaining fast operational velocity to why you need founder-minded people on your team instead of manager-minded people—even among your managers. And yes, he spills the dirt on Deel. 

Parker is one of the new greats who is tearing up the old CEO rulebook and writing his own.
