有余 Youyu
A fulfillment layer for surplus that cannot ship
中文

The same idle resource is a burden here and a scarcity there.

The market is not short of searchable farm stays. What it lacks is a way for a resource that is about to be wasted — cannot be shipped, and whose owner will never list it online — to be used, safely, by someone who actually needs it. Youyu turns off-grid surplus into something you can find, book, pay for in escrow, and attend with someone accountable on site.

Where this is today

This is a working prototype you can click through — not a slide diagram. The national catalog, maps, categories, on-site check-in logic, and county-level replication / partner structure are live on this domain. It is not yet a scaled marketplace of real transactions. Sample listings exist to make the idea concrete.

What “surplus” means here

Anything idle, inefficient, or treated as a burden in place A, and genuinely wanted in place B.

The app only does four jobs

The value happens when a person arrives. Software only paves the path.

Who we want to hear from

People who see this and want to help move it forward: product and engineering, operators who can make density happen on the ground, and people who understand how local development and cooperation actually get done. If that is you, write.

Questions we expect

Is this a fundraising page?

No. It is a product you can inspect and a structure you can read. Conversations happen by email or the form — not as a public raise.

Can I place a real order today?

You can walk the flow to understand the product. Scaled real fulfillment and settlement follow formal operations. Treat this as a clickable specification.

Why does an overseas desk need this?

The thesis is not provincial: mismatch between idle capacity and real demand, fulfillment that happens on site, organizing supply that will never self-list. The English page states the same facts.

How does this relate to local government programs?

Ground operations go through county organization and compliance. Details are not on this page. The right people should just write.
