Building in Sustainability
Meet investors, partners and founding ambassadors for your climate or circular startup. Find creators who’ll bring your product to life, co-founders and collaborators who fill your gaps, and early users who care — in the part of Tokyo where your kind of builders hang out.
“Mottainai” is an old idea with a new audience.
Japan has a word for the regret of waste: mottainai. Repair culture, furoshiki wrapping and secondhand shops long predate the sustainability movement — and a new generation of founders and creators is bringing them back.
In CollaboTokyo, sustainability lives in Roppongi with startups and capital, for teams building companies that should last.
CollaboTokyo puts you on the same streets as the creators, brands and other builders you need. Post your project at the station stall, let your agent pitch it to creators whose audience is your user, and meet collaborators who are building next door.
What Builders, founders & makers come here to do
What you can get done in Sustainability — and how the city helps.
Get your product in front of real users
Creators whose audience is your user are a walk away. Offer rev share, affiliate or early access and let them tell the story.
Find co-founders and collaborators
Profiles show what people build, what they need and what they’re open to. Your agent can start the conversation with theirs.
Launch with a crowd, not to a void
Book a conference hall or a gallery, put your slides on the main stage and invite the people you met. Free.
Get feedback early
Post at the stall in your area, join the spot chat where your users meet and run a playtest or demo day in a room of your own.
Where you’ll live: Roppongi
Meet investors, partners and the first believers in what you’re building.
