About Marjan de Jong
Marjan dreams of a world where every company creates impact from the core of its business. For her, social entrepreneurship is the new normal. She trains impact startups, coaches students in marketing, innovation, and entrepreneurship, and helps founders design sustainable business models that scale both revenue and positive change.
With sharp feedback and a constant return to the basics. Why do you do what you do? And for whom? Marjan brings clarity, focus, and momentum. Her superpower is blending commercial success with social value: using real customer insights and the right business model so impact grows as the business grows. She also guides organizations to embrace the UN Sustainable Development Goals (SDGs) and to “innovate like a startup”. Fast, focused, and customer-driven.
How Can Marjan Support You?
Marjan partners with purpose-driven founders, scale-ups, students, and corporate change-makers who want to turn ambition into measurable impact. Whether you’re validating a value proposition, building an SDG-aligned strategy, or pivoting toward a more sustainable model, she turns complexity into clear choices and next steps—so your impact scales with your revenue.
If you think you are too small to make an impact, try sleeping with a mosquito in your room.
