Frequently asked questions
Who runs investment decisions at QB Capital?
Representative Partners Tsuyoshi Sakamoto and Takashi Hondo lead investment decisions. Sakamoto is a Kyushu University alumnus who teaches at the university's graduate school of business innovation; Hondo brings operating experience as an outside director at precision-instrument and biotech companies. They are supported by Investment Manager Noriyuki Kawata.
How does QB Capital source proprietary deal flow?
QB Capital sources through designated venture-capital certifications from Kitakyushu City and Hamamatsu City, and it serves as a commercialization-promotion organization under Japan's START program and the JST university-originated new-industry creation fund. The firm also holds comprehensive partnership agreements with institutions such as Kyushu Institute of Technology and participates in a national network of university-startup platforms stretching from Hokkaido to Hiroshima.
Is QB Capital structured as a single family office or does it operate more like a venture firm?
QB Capital operates as a venture capital firm structured as a limited-liability company. It does not manage a single family's wealth; the firm raised external capital from institutional limited partners to form QB 1号ファンド and QB 2号ファンド.
What investment stages does QB Capital typically target?
The firm targets early-stage and growth-stage rounds. Its strategy focuses on university-born, real-tech startups from the seed phase onward, often entering at the point where the technology still needs to cross the commercialization gap from research lab to market.
Which sectors does QB Capital explicitly avoid?
The firm's disclosed positions are concentrated in real-tech — advanced materials, precision machinery, biopharma, and health-science devices. There is no evidence of investment in consumer internet, financial services, or software-only business models.
What is QB Capital's known posture on co-investments alongside external GPs?
QB Capital deploys directly from its own fund vehicles, often as a lead or sole institutional investor in pre-revenue rounds. It has not publicly described a co-investment program alongside external GPs; its model relies on proprietary university sourcing rather than syndicate participation.
Where does the underlying wealth come from?
There is no underlying family wealth. QB Capital is a general-partner-led venture firm that raised its capital from external limited partners. The firm explicitly describes its fund formation process as an entrepreneurial act — 'we raised capital and formed a fund, so we too are entrepreneurs.'
