Selfmastered is the Founder Performance Institute. We use Neuroexecution (neuroplasticity applied to execution) to train Execution Capacity, which separates stuck founders from elite operators. Most 6-7 figure founders work 10-12-hour days and get 2-3 hours of high-leverage output. They've tried every book, system, coach, and app. Nothing sticks past two weeks. That's not a discipline problem. That's a capacity ceiling, and it's trainable. Our 16-week protocol rebuilds the neurological capacity that drives focus, follow-through, and decision-making under stress. Every founder tracks their shift through the Execution Score dashboard. Results from 400+ founders: median 2.4x revenue in 12 weeks for 6-figure founders. 3x revenue-driving output. 78% reduction in procrastination and self-doubt. 90% less burnout. We have 4.7 score on Trustpilot and 27% client-to-case-study rate (vs <1% industry average) Founded 2020. Led by Horacio León Castillo, Professor at IE University
