From The Founder, León Castillo
Who We Are
Selfmastered is a peak performance institute for entrepreneurs. This is where the top 1% of entrepreneurs unlock their full potential through peak performance protocols, tools & accountability.
Our Vision
Become the world’s leading performance training center, the “Harvard of Scientific Self-Development and Performance” to help 1,000,0000 entrepreneurs become elite performers and build elite-performing teams through evidence-based, data-driven training & coaching.
Our Mission
Create the World's Best Training & Coaching Methodology to Help Founders master core performance skills that schools don't teach that guarantee success across four verticals: spiritual, mental, physical & executive performance.
What we Believe In
We believe entrepreneurs deserve to win the game of business because they move the world forward. Yet, few ever build the business they aren't ready to perform at their best daily. As a result, they struggle to remain effective, focused and consistent, and end up overwhelmed, frustrated and out of balance when building their business. Selfmastered was born to change that.
Our Values
Excellence
We believe in sustaining the highest standards. For us, it's either 'insanely great or nothing'.
Service/Hospitality
We strive to be one of the top 5 decisions of our clients’ life.
Adventure
We seek to do what others won't to get results others can't even fathom.
Play the Long Game
We aren't in business to build a great company, but an enduring legacy. This informs every action we take.
Selfmastered In Numbers
At Selfmastered, we avoid unsubstantiated advice and focus strictly on what can be proven. Our commitment is to deliver evidence-based strategies that yield tangible, measurable outcomes. We assess progress using a blend of quantifiable and qualitative KPIs, leveraging both self-assessments and our proprietary tools to ensure continuous improvement and tangible results.
