## Questions

### How does G-STARTUP relate to GLOBIS Capital Partners?

G-STARTUP is the seed-stage investment vehicle operating within the broader GLOBIS ecosystem, while GLOBIS Capital Partners (GCP) manages later-stage venture funds. The two share infrastructure, networks, and brand. Soichi Kariyazono, GCP's co-founding partner, provides institutional oversight, and portfolio companies from G-STARTUP can graduate into GCP funds for follow-on rounds.

### Who makes investment decisions at G-STARTUP?

Natsuki Tamura serves as Director of G-STARTUP and leads the Venture Support Team at GLOBIS. While ultimate investment committee authority is not publicly disclosed, Tamura's operational leadership role and Reiji Yamanaka's fund management position indicate a team-based decision structure drawing on GLOBIS Capital Partners' institutional venture processes.

### What stage does G-STARTUP typically enter?

G-STARTUP targets early-stage, pre-Series A startups — effectively the seed round. Its strategy is described as backing 'start-up, venture (general)' companies. The firm fills the earliest institutional check position within the GLOBIS ecosystem, ahead of GLOBIS Capital Partners' core fund entry points.
