ABOUT US.
We advise individuals, boards, charitable institutions and businesses on how to give well, partner wisely, and leave a lasting legacy.

WHERE REASON MEETS RESPONSIBILITY.

Voltaire is a boutique philanthropy consultancy rooted in Enlightenment ideals, reason, dignity, and evidence, reimagined for modern capital. Proudly founded and led by women, we bring a distinct lens to the practice of giving: one that challenges legacy conventions, centres overlooked causes, and treats generosity not as sentiment, but as strategy.

We created Voltaire in response to a problem we saw time and again: that too much capital is deployed without precision, accountability, or long-term vision. Philanthropy, in its most powerful form, is not charity, it is stewardship. And yet, across boardrooms and foundations, we witnessed a deficit of discernment: urgent issues left unfunded, vanity projects praised and outcomes unmeasured.

Voltaire was built to correct that. Our mission is to help patrons and institutions give well: with rigour, humility, and impact that compounds across generations.

Between us, we bring years of cross-sector expertise from international law and private intelligence to humanitarian leadership, public affairs, and the arts. This range allows us to operate with intellectual fluency and cultural sensitivity, advising UHNWIs, family offices, NGOs, and corporate leaders with discretion and depth.

As women leading in a space still dominated by traditional finance and legacy philanthropy, we are unapologetically values-led.
We believe what is funded defines what is prioritised and that whose perspective is at the table changes what is seen.

Our role is not to tell you what to care about. It is to sharpen the alignment between your intent and your impact and to help you deploy your capital with the same intelligence, elegance, and discernment you apply everywhere else in your life.

This is not charity as performance.
This is capital with conscience.
This is Voltaire.

Female Founded. Ethically Driven. Strategically Led.
