Drawing on decades of experience advising ultra-high-net-worth individuals and foundations, this white paper explores the potential of high-impact philanthropy. We welcome all generosity, but this guide is intended for donors making substantial charitable investments—those with the opportunity to leverage their resources toward meaningful, scalable impact. The evidence reveals a fundamental truth: all giving is not the same.

An Oxford University study found that most donors believe the best charities are only 1.5 times more effective than average, when in fact the most impactful solutions can be up to 100 times more effective.

As lead author Lucius Caviola notes, “People drastically underestimate how much more good some charities do than others. That’s a huge opportunity for improving lives through better giving.”

Especially because so many philanthropists today feel the weight of responsibility as they aspire to breathtaking scale and lasting change.

The purpose of this paper is to inspire and equip philanthropists—whether your contributions are modest or substantial—to practice High-Impact, Purpose-Driven Giving. By blending personal passion with results that matter, you can align what you care about with transformative outcomes.
