Chiba Dojo Fund operates as an entrepreneurial community integrated with venture capital capabilities, actively investing across seed, early, and later-stage startups. This unique model fosters an environment where approximately one hundred visionary entrepreneurs collaborate and support each other. The firm primarily backs founders across diverse industries, offering both capital and a robust network to aid in their growth and ultimate success.
The Chiba Dojo Fund was established in 2019 by Kotaro Chiba and Takaki Ishii, building on an insight from 2014 that a founder-led community paired with venture capital would significantly benefit emerging companies. Kotaro Chiba, a seasoned entrepreneur and angel investor with a background at Colopl Inc. and as founder of Drone Fund, brought extensive industry experience. Takaki Ishii, who founded the online learning platform Aoi Zemi, recognized the need for a collaborative environment for founders to share challenges and mutual support.
The firm's focus is on visionary founders, welcoming them into its exclusive community. Chiba Dojo Fund provides active support to its portfolio entrepreneurs from initial investment through to a successful exit, including IPO. Its long-term vision is to continue building a powerful ecosystem where investment decisions are driven by the aim of expanding and strengthening this founder community, supporting those who are shaping the future.
