We did that in 2014. The process is straight forward and is called a Delaware flip (if I remember correctly): you setup a C-Corp in the US and then do a share flip for all share holders in the EU company to the same percentage in the US Corp. this will make the shareholders of the original company stock holders of the US one and the original company becomes a wholly owned subsidiary of the US one (or can be folded if no liabilities are left and no need for it exists)
Super. Would be very interested to know if this is possible with a Spanish company. From hearsay, Spain is supposed to be way harder than Netherlands or UK.
I see all of the founder's shares and options are owned by Rients.org BV and would love to know a bit more about the structure.
Seems like EU companies eventually become American and I would love to know how :)
