About the founder
Martijn Sonderwal
CEO | Entrepreneur | Performance coach
Ambitsi was founded by Martijn Sonderwal, a high-performance coach with a background in elite military and law enforcement special forces. With years of experience in pushing human potential to the limits, he saw a gap in how people develop their skills—too much theory, not enough action.
Driven by the belief that success is built on practical, no-nonsense strategies, Martijn created Ambitsi to make (high) performance training accessible to everyone. Inspired by the proven methods of special forces, Ambitsi offers fast, effective, and results-driven e-learning designed to help people unlock their full potential.
'HIGH
PERFORMANCE ISN’T A GIFT—IT’S A CHOICE. MASTER YOUR MINDSET, SHARPEN YOUR
SKILLS, AND TAKE CONTROL OF YOUR FUTURE.'
- Martijn Sonderwal

Mission statement
In today’s fast-paced world, both adults and youth face increasing pressures—whether it’s workplace stress, relationship challenges, social media pressure, or academic expectations. Many struggle with burnout, anxiety, and adapting to constant change.
Without strong human skills such as emotional intelligence, communication, and resilience, it’s difficult to navigate these challenges successfully. These essential skills are now more important than ever for thriving personally and professionally.
Together we can
change the world
What we strive for: We envision Ambitsi, the performance academy, as the standard for anyone seeking to develop human skills—not only for adults but also for the younger generation preparing to enter the workforce. We believe that with the right support and resources, everyone can strive toward their greatest potential and make a lasting impact in their communities.
