Web builds, software, design, consulting, quote requests.
Crowdsourcing is crowded with bids. SNS doesn't reach the right people.

broadcasting your RFP across SNS, LINE,
and QR-coded posters that reach pros in the real world.
AI analyzes the ripple of cooperation and suggests where to spread next.
Meet the partner who's truly serious about your project, fast.
That's the power of a Cooperation OS.
✓ Free to use ✓ No app install required ✓ Posts in under 3 minutes

Once prepared, your post can quickly start reaching people through YOROSIX.

YOROSIX is a web platform where you can easily post and spread your cooperation requests—
whether it’s outsourcing a job, collecting quotes, or finding a professional.
Each post becomes its own dedicated page, ready to be shared via SNS or LINE.
It’s like recreating the good old “paper bulletin board” using digital tools.

YOROSIX offers a "Real-world Poster Generator" feature that turns your cooperation request into a printable, QR-coded poster.
This helps convey your message effectively and reach a wider audience.
The generated posters can be downloaded in JPEG format.


Your privacy is respected, so you can use the service with confidence.
