Frequently asked questions
Who runs investment decisions at Mobile Internet Capital?
The firm lists five Fund Managers — 海老澤 観, 元木 新, 稲垣 泰仁, 木本 恭介, and 苗 春亭 — alongside a network of Advisers and Mentors. Investment decision-making authority appears concentrated among this group, though delegation structures are not publicly disclosed.
What investment stages does Mobile Internet Capital target?
MIC covers the full venture lifecycle, from seed and start-up through growth and pre-IPO. The firm's website emphasizes early-stage technology companies with unique business models, and its portfolio includes later-stage positions tied to technology and telecommunications expansion.
Does Mobile Internet Capital invest outside Japan?
While its primary focus is domestic Japanese startups, MIC's historical portfolio includes US-based semiconductor and infrastructure companies such as SiTime, SiRF Technology Holdings, and Ruckus Wireless, as well as China-based Asia Media Co. Current activity appears concentrated in Japan.
Is Mobile Internet Capital a corporate venture capital arm?
No. MIC is an independent venture capital firm, unaffiliated with any single corporate parent. This structural independence differentiates it from many Japanese venture investors that operate as CVC units of large trading companies or financial institutions.
How does Mobile Internet Capital source deals?
Specific deal-sourcing channels are not publicly described, though MIC's 25-year operating history and broad sector coverage suggest a founder-referral and ecosystem-based origination model, consistent with an established Tokyo-based venture firm.
