Technical Excellence First
We believe the best companies are built by founders who deeply understand the technical challenges they’re solving. We look for teams with the expertise to build what others cannot.
Sky9 Capital traces its roots to a simple belief: that technology can transform industries and improve lives. Named "Yunjiu" in honor of our founding partner's grandfather—the first in his family to study at Harvard—we carry forward his pioneering spirit and commitment to education and opportunity.
Sky9 Capital was founded in 2016 by partners who had been collaborating since 2011. From their early days of working together, they witnessed firsthand technology's power to reshape markets, which inspired the firm's clear mission: to back exceptional technical founders solving hard problems with AI and frontier technologies.
We bring more than capital. Having built and scaled companies ourselves, we understand the journey from idea to IPO. Our partners have led engineering teams, closed enterprise deals, navigated regulatory challenges, and scaled operations across continents.
