Along with World-Changing Startups.

We nurture startups that tackle global issues and help them build the foundations of their organization and management.
The way we nurture startups is called “Bansou” (kanji: 伴走) support. Bansou is the term used in sports for a person that runs alongside a marathon athlete, and with the intention of success, guides them through the race side-by-side.
Leave a Nest Capital is the companion that bridges “science and technology” and “business growth”.

Our Support1


We provide support for the deep tech venture companies to organize administrative operations from their start-up phase, including daily accounting operations, labor management, and assistance in designing salary and evaluation systems.

For those who are starting venture companies with a small number of members that are mostly researchers or engineers, we propose the establishment of a workflow tailored to each growth phase of the company through consultation on general administrative operations and by undertaking some administrative tasks.
