SunBridge Global Ventures
George Hara launched SunBridge Global Ventures in 1996, establishing a multi-family office rooted in entrepreneurial wealth from technology and venture capital. The firm operates offices in San Francisco, Tokyo and Tel Aviv, giving it a distinctive position bridging the US, Japanese and Israeli innovation ecosystems. SunBridge targets early-stage enterprise software, digital health and climate-tech startups, alongside direct co-investments and venture capital fund commitments. The firm also maintains a real estate portfolio in the US and Japan. Portfolio companies include cybersecurity firm Cybereason, fintech company Payoneer and robotics provider Mujin (per public record). Deal sourcing relies on Hara's network built over three decades in the US-Japan venture community. The organization employs a lean team of investment professionals across its three offices. Adjacent structures include philanthropic initiatives focused on US-Japan bilateral exchange and education. SunBridge operates as a multi-family office structure, aggregating capital from a limited circle of high-net-worth families. A structural differentiator is SunBridge's explicit three-region mandate and sourcing model. Most family offices concentrate in one geography; SunBridge systematically deploys across the US, Japan and Israel, using physical offices in each hub to source proprietary cross-border tech and real assets.

Frequently asked questions
Who makes investment decisions at SunBridge Global Ventures?
George Hara, founder and chairman, leads strategic direction. A small team of investment professionals in San Francisco, Tokyo and Tel Aviv execute day-to-day operations. The exact CIO or CEO title has not been publicly disclosed for recent years.
What is SunBridge's geographic focus?
SunBridge explicitly bridges three regions: the United States (primarily Silicon Valley), Japan and Israel. Offices in San Francisco, Tokyo and Tel Aviv cover each hub, allowing the firm to source cross-border technology deals that other family offices miss.
Does SunBridge invest via funds or only direct deals?
It does both. SunBridge commits capital to venture capital funds and makes direct co-investments alongside those GPs. The firm also holds real estate assets in the US and Japan.
How is SunBridge related to other vehicles or foundations?
SunBridge operates as a distinct multi-family office structure. It has philanthropic initiatives centered on US-Japan exchange and education, but no large public foundation. No spinout vehicles have been publicly identified.
What sectors does SunBridge avoid?
No explicit avoidance list is public. Based on known portfolio, the firm does not invest in oil and gas, commodity trading, or public equities. It focuses on early-stage technology (enterprise software, digital health, climate tech, fintech, AI/ML) plus real estate.
What is the wealth origin of the families served?
The founding wealth comes from George Hara's entrepreneurial and venture capital career in technology. The additional families in the multi-family structure are not named publicly.
How many professionals work at SunBridge?
Team size is not publicly disclosed. The three-office structure suggests a lean headcount, likely under 20 investment professionals across all locations.
