Blueseed is a Silicon Valley-based startup company and a seasteading venture to create a startup community located on a vessel stationed in international waters near the coast of Silicon Valley in the United States.  The intended location (outside the territorial seas of the United States, 12 nautical miles from the coast of California, in the so-called “contiguous zone”) would enable non-U.S. startup entrepreneurs to work on their ventures without the need for a US work visa (H1B), while living in proximity to Silicon Valley and using relatively easier to obtain business and tourism visas (B1/B2) to travel to the mainland.  After the conclusion of their incubation on the vessel, successful startups may relocate to Silicon Valley and employ local workforce.
