Silicon Valley-based Yu Galaxy has closed $90 million for its third fund, pushing the firm’s total assets under management past $500 million. This milestone puts founder PR Yu among the few solo general partners who operate at an institutional scale and still have full control over their funds.
Yu Galaxy invests from seed through Series B in healthcare, AI infrastructure and automation, backing startups using breakthrough technology to tackle global challenges. The firm raised capital from entrepreneurs, high-net-worth individuals and family offices, many of whom Yu has worked with across multiple funds.
Yu Galaxy was one of the first investors in Leo Cancer Care, which has developed radiation therapy that lets cancer patients receive treatment while upright, which it says is more effective and reduces the need for giant, rotating machinery. The technology is now used at Stanford Medicine, Dana-Farber Cancer Institute, and the Mayo Clinic.
Another portfolio company, Capstan Medical, builds surgical robots for heart procedures and recently performed the first robot-assisted mitral valve replacement. Wibotic, based in Seattle, supplies wireless charging systems for more than 15,000 robots and devices used in warehouses, hospitals, and even space.
New York-based InsightFinder AI helps prevent AI model “drift,” remediate hallucinations, and detect anomalies.
“We don’t think social impact is separable from financial return,” Yu told ImpactAlpha. “When you solve a big social need and make a big social impact, the financial return will come. It’s two sides of one coin.”
The firm aims to impact 1 billion lives through its portfolio companies over the next ten years.
Solo GP momentum
A solo GP fund, with a single decision-maker for fund deployment, is a model that has been getting traction in Silicon Valley over recent years as founders have amassed wealth and created funds to invest it. In 2020, solo GPs were a minority among emerging fund managers. By 2024, they accounted for over half of all new VC funds.
The structure allows for faster decisions and clearer communication with founders. Yu can commit capital in weeks rather than months, and for follow-on rounds with portfolio companies, sometimes in days. It also gives former founders and operators a chance to leverage their experience to help other startups grow.
“Solo GP just means there’s one decision maker,” said Yu, who founded Optony, a solar technology company, and co-founded SV Tech Ventures, a deep-tech investment firm, before starting Yu Galaxy. “Unlike most firms with committees, I make the calls myself. It’s the same mindset I had as a founder and CEO — making tough decisions quickly and serving entrepreneurs better.”
