Bold thinking. Measurable impact.
Challenging the status quo to achieve real-world progress.
At the Sijbrandij Foundation, we pursue under-explored solutions with the potential for 100x social return. We believe unconventional ideas have the power to unlock meaningful and measurable change.
What we do
We seek projects that deliver impact at one of three levels:
For individuals—by creating access to opportunity and upward mobility.
For communities—by fostering engagement and economic vitality.
For societies—by supporting systemic change and incentive alignment.
Areas of focus are education, healthcare, housing, climate solutions, and big art. We empower visionary thinkers who dare to challenge norms and pursue bold solutions that others overlook.
Recent projects include addressing climate change, developing charter cities and local economies, offering public big art and thought-provoking interactive experiences, and designing new areas of research into human behavior.
