Investment Policy

Investment Areas

While covering the entire Internet/technology domain, we invest in a wide range of startups with a focus on X-Tech (fusion of the Internet and the real world). The two main areas of investment are: (1) "industry transformation businesses" that solve problems faced by existing industries, and (2) "new industry creation businesses" that create new industries using leading-edge technologies and business models.

Investment Stages

We invest in early-stage and later startups that have passed the hypothesis verification phase and are moving into the business expansion phase. After the initial investment, additional investments can be made in subsequent rounds depending on the situation.
We aim to invest 100 to 500 million yen for early-middle stage startups and 500 to 1 billion yen for later stage startups.

Hands-on Support

We provide a variety of management support to our portfolio companies. We support our portfolio companies to increase their value by collaborating with external partners as necessary.


Innovation Support

Through Spiral Innovation Partners, we provide comprehensive support for the promotion of open innovation.
