Yu Galaxy Secures $90M Raise to Surpass $500M AUM, Redefining How Venture Capital Invests in Global Challenges
PALO ALTO, Calif – In a landscape dominated by big-name firms and sprawling teams, Yu Galaxy stands apart — one investor and a mission to tackle some of humanity’s hardest problems. With the close of $90 million for Yu Star Fund III and a special purpose vehicle (SPV), the Silicon Valley firm has reached $500 million in assets under management (AUM),underscoring the growing influence of lean, solo GP-led venture firms.
PR Yu brings a rare perspective to venture capital. He earned a Ph.D. in physical chemistry and spent more than a decade conducting advanced research before becoming a founder-CEO himself. Yu built and scaled startups from the ground up, giving him firsthand insight into the challenges founders face. For the past ten years, he has applied that scientific rigor and entrepreneurial experience as an investor, backing more than 100 startups across healthcare, AI, and deep tech.
While solo GP-led funds remain a small segment of the industry, their momentum is accelerating. According to PitchBook, they account for less than 5% of total U.S. venture assets, with only a handful crossing the half-billion threshold. Yu Galaxy’s milestone highlights the advantages of this conviction-driven approach — one that moves faster, backs bolder founders, and provides hands-on guidance without the bureaucracy of large partnerships.
“We are transforming the way venture capital is practiced — not by being bigger or flashier, but by staying true to purpose,” said PR Yu, Founder and General Partner of Yu Galaxy. “From the start, I made a deliberate choice to only fund mission-driven companies addressing society’s most urgent challenges. As a lean, solo GP-led firm, every decision and every dollar must be intentional — and that discipline allows us to deliver both strong returns and maximum social impact, while serving our founders as true partners.”
Investing with Purpose at Scale
Founded in 2020, Yu Galaxy is driven by a single mission: to fund technologies that directly confront humanity’s most critical challenges. The firm invests from seed through Series B and follows on through exit, backing startups in areas such as cancer treatment, heart disease, national defense, resilient infrastructure, and responsible AI.

“PR cared deeply about our mission to save lives, but more importantly, he gave us the resources and strategic guidance to make that mission real,” said Stephen Towe, CEO of Leo Cancer Care. “Today, patients at world-class hospitals are benefiting because he stood behind us.”
“PR not only invested first, he has remained a true partner,” said Dr. Diana Gamzina, Founder and CEO of Elve. “His input on strategy and fundraising has helped us scale Elve from concept to contracts in aerospace and defense, where our technology is already making an impact.”
Why It Matters Now

With $500M AUM, Yu Galaxy demonstrates how a lean, solo GP-led approach can scale to institutional levels — without sacrificing purpose.
