Turn undefined ideas
into ventures built
for the world.
For founders, researchers, and creators building from Day 0.
D-0. is a cross-border venture creation platform across Japan and Singapore.
This platform integrates and accelerates the entire process from concept development to prototyping, validation, and venture business creation.
We nurture questions and ideas that are not yet fully formed into businesses through dialogue and practice, while generating new knowledge and implementing it in society.
Throughout the process, we re-examine what “Fulfillment” means for future society and shape it into new forms of value.
Why D-0.
Supporting the journey from concept to venture creation in one continuous flow.
In venture creation, the initial concept stage greatly influences subsequent development.
From the very beginning, D-0. mentors will provide hands-on support to the founders, integrating prototyping, validation, funding, and company formation into a unified journey that culminates in a global scale business.
This design is a direct result of the co-creation between JT and Leave a Nest, emerging from our deep involvement in tackling the challenges of bringing new businesses to life.
Building on these insights, we connect the markets of Japan and Singapore into one cohesive track to drive continuous business creation.
Program
More than just a vision: a one-year program dedicated to rigorous execution and tangible results.
During the first six months, we sharpen the focus of the core question and the business vision.
In the following six months, we turn that vision into action through prototyping, validation, and pathways to commercialization.
D-0. is engineered not as a mere educational course, but as a continuous trajectory that bridges the gap between insight and enterprise.
