We build Geoyuan
to a Network state

A distributed, borderless crew building toward a network state. We are recruiting builders from all over the world — prove you belong.

Not just another group.

Geoyuan is a small, globally distributed team. We do not care about passports or time zones — we care about people who ship, think, and stay curious. This is a site in building for our crews and for those who want in.

Founded in Hangzhou, China. Our long-term bet: a sci-fi company and a network state, built in the open. If that sounds like your kind of strange, keep reading.
