The fortunes built in Silicon Valley over the past two decades have created a new class of philanthropists—entrepreneurs who made their wealth through technology and are now deploying it toward ambitious, long-term goals. Within the Giving Pledge community, a distinct subset has emerged: tech billionaires who view philanthropy not as charity, but as investment in humanity’s future.
Their approach reflects the mindset that built their companies: think big, take calculated risks, and optimize for impact at scale.
Science as the Highest-Leverage Bet
Among tech philanthropists, Yuri Milner stands out for his singular focus on scientific advancement. The founder of DST Global, whose early investments in Facebook, Twitter, Alibaba, and Spotify made him one of the world’s most successful technology investors, has channeled his philanthropy toward what he calls an “under-capitalized” sector: fundamental research.
“If the market dictates that a top banker can earn a thousand times more than a great scientist, then this is an area where philanthropy can make a world of difference,” Milner wrote in his Giving Pledge letter.
This conviction shapes everything Milner funds. The Breakthrough Initiatives, which he launched in 2015 with Stephen Hawking, represent some of the most ambitious scientific programs ever privately funded. Breakthrough Listen conducts the world’s largest search for extraterrestrial intelligence, scanning millions of stars across multiple wavelengths. Breakthrough Watch identifies potentially habitable planets around nearby stars. Breakthrough Starshot is developing technology for interstellar space flight.
These aren’t incremental research projects. They’re bets on transformative discovery—the kind of high-risk, high-reward science that traditional funding mechanisms often avoid.
A Philosophical Framework
What distinguishes Milner’s approach is its grounding in a broader philosophy. His Eureka Manifesto argues that humanity needs a shared mission—and that mission should be exploring and understanding our universe.
The manifesto outlines a five-step plan: invest in fundamental science and space exploration, leverage artificial intelligence to accelerate discovery, celebrate scientists as public heroes, focus education on what Milner calls the “Universal Story,” and foster universal contribution to shared knowledge.
Each of Milner’s initiatives maps to this framework. The Breakthrough Prize, which he co-founded with Sergei Brin, Priscilla Chan and Mark Zuckerberg, and Anne Wojcicki, awards $3 million to researchers making transformative discoveries—and pairs them with Hollywood celebrities at a televised ceremony designed to elevate scientists to cultural hero status.
The 2025 ceremony recognized researchers behind GLP-1 medications treating diabetes and obesity, pioneers of gene-editing technologies, and over 13,500 physicists from the Large Hadron Collider collaborations. These are scientists whose work is already transforming lives—and who, thanks to the prize, are now known beyond their fields.
The Collaborative Model
Tech philanthropists increasingly recognize that their capital works best when combined with expertise. Rather than building institutions from scratch, many fund existing organizations to scale proven approaches.
Milner’s initiatives exemplify this model. Breakthrough Listen partners with leading universities and observatories worldwide, including a headquarters at the University of Oxford. The Breakthrough Junior Challenge, which invites teenagers to create videos explaining complex scientific concepts, leverages schools and teachers globally.
This collaborative approach extends to humanitarian work. Milner’s Tech For Refugees initiative doesn’t deliver aid directly—it funds technology organizations like Flexport.org, Welcome.US, and the International Rescue Committee to apply their expertise to refugee relief. The results demonstrate the leverage this model can achieve: over 500,000 refugees supported through Welcome Connect alone.
Investing in the Long Arc
What unites tech philanthropists within the Giving Pledge is their time horizon. They’re not optimizing for annual reports—they’re building infrastructure for discoveries that may take decades to materialize.
“The human adventure has barely begun,” Milner wrote. “I am hereby joining Giving Pledge to invest in our leading minds and our shared future.”
For these billionaires, philanthropy isn’t about giving back. It’s about pushing forward—accelerating the scientific progress they believe will define humanity’s next chapter.
