Investment thesis
KUSABI draws its identity from the wedge (kusabi), a tool used for over 9,000 years both to split objects apart and to bind them together. The firm frames these seemingly contradictory roles as its mission: driving through difficult situations to break new ground, while connecting risk capital with entrepreneurs to create new value. KUSABI seeks to remain a timeless, universally needed presence in venture capital, much like the wedge itself has endured across ages.

Cherubic Ventures is known for investing before a startup even launches or reaches product-market fit, often as the first institutional investor, while also setting aside half of its latest fund for follow-on support all the way through pre-IPO; it was also one of the first venture firms to operate as a solo general partner and has grown into one of the largest funds run that way. Founded by Matt Cheng, who previously built two companies that each reached over $1 billion in public market value, the firm was designed from the start to invest across both the U.S. and Asia, backing early breakout companies in places like Croatia, Bangladesh, Japan, and Taiwan in addition to the U.S., with its Taipei roots still central to its identity alongside its Silicon Valley presence.
