## Questions

### How does SunBridge source proprietary deal flow?

SunBridge leverages founder Allen Miner's deep network from his tenure as a founding executive at Oracle Japan. The firm sources opportunities through its dual presence in Tokyo and Silicon Valley, often acting as the first institutional call for Japanese enterprise-software startups seeking US market entry and for US startups requiring a launch partner in Japan. This cross-border origination model is distinct from regionally constrained seed funds.

### What investment stages does SunBridge typically target?

SunBridge concentrates on seed and Series A investments, occasionally participating in later-stage rounds for existing portfolio companies. The firm's sweet spot is a startup with a working product and initial customer traction that needs capital and a bridge to enterprise customers across the Pacific. It does not operate an accelerator or incubator, distinguishing it from studio-model investors.

### How is SunBridge's bilateral structure different from a typical Japanese venture firm?

Unlike purely domestic Japanese venture firms, SunBridge has maintained a permanent office presence in Silicon Valley since its founding. The firm invests in US-domiciled companies and actively facilitates their Japan market entry through relationships with Japanese corporate partners. This is not a fund-of-funds arrangement or a limited-partner role — SunBridge takes direct board seats and plays a hands-on operating role for portfolio companies entering the Japanese market.

### Does SunBridge invest primarily from Japan-based limited partners?

Yes, SunBridge has historically raised the majority of its capital from Japanese corporate and institutional limited partners seeking exposure to enterprise-software and AI/ML startups. The firm's alignment with Japanese corporate LPs directly supports its model: capital partners often coincide with early customers or distribution partners for SunBridge portfolio companies in Japan.

### What sectors does SunBridge actively pursue?

The firm focuses on enterprise software, AI/ML infrastructure and applications, and digital health. Notable historical investments include data-storage platform Cloudian and analytics provider Mode. SunBridge generally avoids consumer internet, hardware, and deep-tech sectors that lack immediate enterprise go-to-market alignment with Japanese corporate demand.
