Hey, I'm León Castillo
I’m an entrepreneur, investor in 40+ startups, and university professor obsessed with one question: Why do so many smart, driven founders still fail to execute at the level their businesses demand?
Six years ago I founded Selfmastered after seeing too many entrepreneurs buy more courses and coaching, yet end most days knowing they still didn’t do the work that actually moves the needle.
Since then, we’ve worked with hundreds of 6–9 figure founders, using neuroscience‑based performance protocols originally reserved for Fortune500 CEOs, elite athletes and operators, and tailored them to the reality of running a high‑growth company.
Selfmastered is the antidote to the 1-sided, mostly ineffective executive performance advice most entrepreneurs have to rely on.
We exist to do one thing: Turn you into the operator your business needs you to be, with an execution system that is deep, durable, and measurable, not another 30‑day motivation spike that fades when life gets hard.
