Bring Erin to Your Stage
The Leadership Playbook Has Changed. It's Time We Did Too.
As AI takes hold and economic shocks become constant, leaders are being asked to fight battles they never trained for.
After nearly two decades at leading Silicon Valley technology companies, Erin found a different way to lead in an Amsterdam boxing gym. Boxers call it Ring IQ, the strategic intelligence they use to decide which fights are worth taking, read a fight as it unfolds, and adapt in real time.
Erin developed a proprietary version of Ring IQ for business leaders that underpins her leadership development firm, Fight Co.Lab. Today, she teaches leaders to choose the challenges that matter, lead from their strengths, and make smarter decisions under pressure. The result? Winning finally feels like winning.
What happens when you get everything you wanted—and lose yourself along the way?
About Erin's Forthcoming Memoir
Erin's debut memoir is an unflinching takedown of the fairytale we've been sold about success, identity, and self-worth. Through a deeply personal reckoning with perfectionism, external validation, and the hidden costs of high achievement, it explores what happens when the life you've built no longer fits—and what it takes to find your way back to yourself.
Forthcoming from Simon & Schuster in 2027.
