The signatories of the Giving Pledge support health, education, scientific research and AI

Founded in 2010 by Warren Buffett, Bill Gates and Melinda French Gates, the Giving Pledge unites some of the world’s wealthiest philanthropists in a shared commitment to donate the majority of their fortunes to charitable causes, either during their lifetimes or through their estates. With over 240 signatories from 30 countries, the powerful movement toward impactful philanthropy counts Sam Altman, CEO of OpenAI, and his husband, Oliver Mulherin, among its newest members. Both have pledged to support advancements in technology to uplift people.

“In the face of mounting global crises putting additional demands on public resources, philanthropy fills critical funding gaps and catalyses life-saving innovations,” said Microsoft co-founder Bill Gates. “I’m grateful that so many Giving Pledge signatories have stepped up to take action through their philanthropy.”

Multiplying its influence, the Giving Pledge also connects the world’s most powerful with each other so that they can engage in collaborative philanthropy, combining their ideas, resources and networks to drive greater impact than they could on their own. Over the past year, for example, the Heising-Simons Foundation, led by Liz Simons and Mark Heising and their daughter Caitlin Heising, joined hands with Pierre and Pam Omidyar’s Omidyar Network to foster ethical AI development. The alliance of 10 major donors has committed over US$200 million to mitigate AI’s risks and promote its responsible use.

“One of the Giving Pledge community’s greatest strengths is that members represent so many different countries, generations and perspectives—it helps us learn from and challenge one another,” said Melinda French Gates. “I continue to be inspired by this group and grateful to be part of this community.”

MacKenzie Scott (United States)

In the past year, novelist and philanthropist MacKenzie Scott donated over US$2 billion, which includes giving away US$640 million to 361 community-led nonprofits driving progress on key issues such as health, education and socioeconomic mobility. Scott, the former wife of Amazon’s Jeff Bezos, is the fifth-richest woman in the world, with a net worth of US35.6 billion, according to Forbes 2024 World Billionaires List. “In addition to whatever assets life has nurtured in me, I have a disproportionate amount of money to share. My approach to philanthropy will continue to be thoughtful. It will take time and effort and care. But I won’t wait. And I will keep at it until the safe is empty,” she said in her pledge letter.

Francine A LeFrak (United States)

To uplift marginalised women, including those living in extreme poverty and who have been in the justice system, Francine A LeFrak established the Francine A LeFrak Foundation. For over a decade, the organisation has invested in programmes that teach financial literacy, business, tech and artisanal skills, as well as provides micro-grants to help women overcome barriers to success. In 2023, the philanthropist opened the Francine A LeFrak Wellness Center in New Jersey to provide training and free health services, including medical, dental and mental health care, to court-involved and formerly incarcerated people.

Rohini and Nandan Nilekani (India)

“What should we do at this time? That is a question every citizen must ask. Those of us who have wealth beyond all our wants must ask that very sharply. Wealth comes with huge responsibility and is best deployed for the larger public interest. So what must the super-wealthy do?” asked Rohini and Nandan Nilekani in their pledge letter. Since joining the Giving Pledge, the philanthropists have been catalysts of sustainable change. In the past year, Nandan donated US$39 million to his alma mater, the Indian Institute of Technology Bombay, to support infrastructure and innovation, marking one of the largest alumni donations to an Indian educational institution. Meanwhile, Rohini contributed US$12.5 million to NIMHANS and NCBS to advance mental health research and treatment in India.

Sam Altman and Oliver Mulherin (United States)

Sam Altman, the co-founder and CEO of OpenAI, the tech company behind ChatGPT and Sora, and husband Oliver Mulherin, a technology investor focused on energy, are among the newest signatories of the Giving Pledge. The pair, who joined the Giving Pledge in May 2024, shared their intentions in their pledge letter: “We would not be making this pledge if it weren’t for the hard work, brilliance, generosity and dedication to improve the world of many people that built the scaffolding of society that let us get here… We intend to focus our giving on supporting technology that helps create abundance for people, so that they can then build the scaffolding even higher.”

Marco Dunand and Suzan Craig Dunand (Switzerland and New Zealand)

Marco Dunand is the CEO and co-founder of Mercuria, one of the world’s largest privately owned energy and commodities trading firms, with revenues of more than US$150 billion, while Suzan Craig Dunand is a New Zealand-based entrepreneur focused on ecosystem restoration and sustainable practices. In 2022, the Dunands co-founded the Villars Institute in Switzerland, aiming to advance a net-zero, nature-positive economy through interdisciplinary research and youth engagement. In March 2024, the organisation gathered over 280 experts, entrepreneurs, investors and philanthropists to address the climate and biodiversity crises. “We are excited to... make a meaningful difference for the planet, and to learn from the collective wisdom and experiences of partners from around the world,” they wrote in their pledge letter.

Robert D Goldfarb (United States)

“More than 90 per cent of my capital will be given philanthropically. I expect that the Pledge will enable me to become a better philanthropist. My hope is that the Giving Pledge will enhance my sense of urgency to give during my lifetime, for which I have a decided preference,” declared Robert D Goldfarb. The equity investor was the chairman of asset management firm Ruane, Cunniff & Goldfarb from 2005 to 2016, and the co-manager of Sequoia Fund, the mutual fund that bucked industry expectations by outperforming all others in 1975. Goldfarb, who is now retired, credits his mentor Bill Ruane and his father as the biggest influences on his giving.

Jahm and Cheryl Najafi (United States)

“Supporting the underserved is critical when too many suffer diminished access to success paths. We’ve frequently and anonymously supported education and the arts, recently adding social justice and equity. We’re now publicly aligning ourselves with these causes so that others may be similarly inspired to give.” said Jahm Najafi. The international investor is the founder of The Najafi Companies, vice chairman of the Phoenix Suns, a member of the NBA’s Board of Governors and vice chairman of McLaren F1 Racing Team. His wife Cheryl, meanwhile, is an author, speaker, activist, and entrepreneur, who founded EverydayDishes.com, The Cause Collection and Kara Aware. Cheryl also established The Broken Butterfly Project, which prevents gun violence and advances sensible gun legislation.

Hemant Taneja is CEO of the global technology investment capital firm General Catalyst, as well as the co-founder of Responsible Innovation Labs, a non-profit consortium of leaders aiming to re-centre technology as a force for good. Jessica Schantz Taneja operates the 90-acre agricultural farm and winery Dhyana Grove Farm and heads a development company for speciality real estate in the Colorado Rocky Mountains. Together, they run the Taneja Family Foundation, which most recently gave a substantial donation to the Tampa General Hospital. In April 2024, the Taneja family broke ground on the Taneja Surgical, Neuroscience & Transplant Tower, which will house the hospital’s surgery, neuroscience and transplant service lines upon its completion. “Our aspiration is to innovate in how we do this work so that technology can be a multiplier for our giving,” they shared in their pledge letter.
