{ Founder Story }
It started in 2010 with $12,000, a shared desk, and a stubborn belief that the industries most resistant to change were the ones most worth attacking.
My first company failed in 18 months. The second one was acquired. The third became a platform. Each time I was building toward the same thing: systems that create compounding value long after I’ve moved on.
Today I run a portfolio of 12 companies, back founders through my angel fund, and lead a global community of 12,000+ operators who believe business is the highest form of creative work.
