Tired of doing business on hard mode?
Like many entrepreneurs we work with, you feel you're not reaching your full potential.
You’re hardworking, committed, and thoughtful, but the high stakes, long work hours, and constant pressure to meet expectations are compromising your productivity, focus, and mental game.
Despite your best efforts to excel daily, distractions, negativity, and exhaustion hinder your results.
You've tried various solutions—self-help books, costly courses, generic coaching, and unvetted communities. Yet, none have led to lasting change.
This is often because unlocking peak performance requires more than generic advice; it demands a deep personal transformation that fundamentally improves how you manage yourself in business.

You don't know what to prioritize and why.

Tailored to your unique situation
Don't settle for generic solutions.

A New Approach to Executive Coaching
At Selfmastered, we believe business growth stems from internal clarity, focus, discipline, and self-belief – performance skills every entrepreneur has the potential to develop.
Unfortunately, most entrepreneurial advice focuses on “technical skills” about what to do (marketing, sales, etc.) at the expense of teaching critical performance skills related to “how and why to do what you do.”
With cutting-edge insights from neuroscience, performance psychology, and behavioral science—and guided by an accountability coach—you'll master these skills in real-world scenarios, achieving deep transformation.
This approach will create a profound psychological and behavioral shift in you, transforming you into an elite-performing entrepreneur.
Reach your next level in life & business
We’ve guided over 300 entrepreneurs to achieve major personal breakthroughs. Just like them, you will learn to perform at your best consistently.

Here’s how we take you to new heights

360º Evaluation
There is no "one size" approach to peak performance training. Every client's transformation unfolds differently.
Upon joining Selfmastered, you'll embark on an intensive self-examination process, which clients have described as 'the most profound analysis I’ve ever experienced.'
This isn't just an evaluation; it's a deep, data-driven, science-backed analysis of your entire performance spectrum.
We examine dozens of key performance indicators across multiple domains to understand how well you manage:
- Your mind: Strengths, weaknesses, personality traits, behavioral defaults, self-talk.
- Your brain: Self-awareness, attention span, cognitive load.
- Your life: Health, development, relationships.
- Your business: Product, marketing, sales, operations.
- Your time: Efficiency, prioritization, time-wasters, distractions.
Within one week, we deliver a detailed Performance Evaluation that clarifies your current status and provides targeted, actionable steps for rapid improvement. This thorough evaluation sets the stage for the next phase of your Selfmastered journey, where we collaboratively craft a personalized roadmap tailored to your personal and professional aspirations.

Guided transformation
Leveraging insights from your detailed 360º evaluation, we tailor a research-backed curriculum designed to enhance your performance as a Founder or CEO systematically.
We focus on critical performance skills—often overlooked in traditional education—that are crucial for business success.
In this phase, we’ll precisely level up your:
- Spiritual Performance (Purpose & intrinsic motivation, core values, presence and mindfulness, etc)
- Mental Performance (Belief system, behavioral defaults, and emotional management, etc..)
- Physical Performance (Stress management, active recovery, burnout-proofing), etc.
- Executive Performance (Strategy, prioritization, time management, planning, flow states)
Our personalized training includes 1-on-1 coaching and group sessions designed to catalyze significant personal growth, equating to what many describe as '10 years worth of development in just 12 weeks.'
You'll gain access to peak performance frameworks, protocols, and mental models that drive continuous improvement, helping you become the best version of yourself in every aspect of your life.
