Investment thesis
Seiho Investment Works believes a VC's role goes beyond supplying risk capital: it must assess investment eligibility, help portfolio companies build sound management, generate returns commensurate with risk, and demonstrate the social and economic value of innovation. Guided by a principle of 'fairness', the firm invests hands-on in seed to early-stage technology companies nationwide across Japan, spanning healthcare/bio, consumer-facing (BtoC) IT, enterprise (BtoB) IT, and deep tech. It provides operational support from founding through maturity, drawing on decades of experience and networks built at Osaka Small and Medium Business Investment & Consultation.
