Eric Guo is a serial founder-turned-investor at Sky9 Capital who built and sold FaceU, a mobile social camera app with AR filters, to ByteDance for around $300 million after scaling it to over 200 million monthly active users. He then served as CEO and Product Manager for ByteDance's camera-based products before joining Sky9's investment team, where he focuses on mobile internet, digital media, and AI-powered consumer products while serving as both a partner and a living example of the firm's long-term founder partnership approach.
About their Fund
Sky9 Capital carries forward a multi-generational family legacy through its name tied to founding partner Ron Cao's grandfather "Yunjiu," the first in his family to study at Harvard, creating unusually personal branding for a VC firm that has raised around $2B across seven funds since 2011 with deep China tech pattern recognition from early backing major platforms like Meituan and Pinduoduo. The firm formalizes VC 3.0 through structured venture philanthropy including dedicated vehicles like the Good Soil Foundation and runs concrete Public Goods programs spanning technical fellowships, open-source grants, and a San Francisco pre-accelerator, positioning itself as a deliberate bridge between China and global markets across nine cities rather than just having multiple offices.
