Creating lasting impact for people and planet

Many important causes rightly receive significant attention and resources. Others- equally important- remain overlooked, under-resourced or insufficiently understood.

Stichting Lisrosa believes philanthropy can achieve its greatest impact by supporting these neglected causes. We partner with ambitious organisations tackling complex challenges where thoughtful, evidence-informed and long-term philanthropy can help unlock lasting systemic change.

Our approach

We actively identify opportunities, undertake independent research and work closely with organisations whose missions align with our principles. Every potential partnership is subject to careful due diligence, with consideration given to the importance of the problem, the strength of the proposed approach, organisational leadership, financial sustainability and the potential for lasting impact.

We believe effective philanthropy combines thoughtful analysis with long-term partnerships, continuous learning and a willingness to adapt as new evidence emerges.

Our philosophy

Our work is guided by four principles:

Focus on neglected causes
We seek opportunities where additional philanthropic support can make a disproportionate difference.

Maximise impact per euro donated
We aim to allocate our resources where they can achieve the greatest possible benefit.

Use evidence and careful reasoning
Our decisions are grounded in thoughtful analysis, continuous learning and a willingness to adapt.

Take a long-term perspective
We recognise that meaningful change often requires patience and sustained commitment.

We recognise that meaningful change often takes time and that tackling complex problems requires patience, curiosity and a willingness to learn. Not every initiative will succeed, but every decision should contribute to a deeper understanding of how lasting impact can best be achieved.
