Under-explored solutions to achieve 100x impact
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, AI interpretability and big art. We empower visionary thinkers who dare to challenge norms and pursue bold solutions that others overlook.
Recent projects include funding bold cancer research, investing in synthetic natural gas development, scaling global digital education, and using public big art as a catalyst for economic development.
