The company told AFP that its investors include Chinese billionaire Jia Yueting, founder of Letv, which is sometimes described as the Netflix of China.
Faraday Future employees include former executives from Apple, BMW, Google, NASA, Tesla and other prominent firms.
Faraday is exploring "new types of ownership" for the vehicles, Sampson said, without elaborating.
Earlier, he told AFP the company was looking at shared ownership options and added that "ownership models will change over time."
Based in California, Faraday Future announced its factory plans in early December, saying it would be a "first phase" for the new company, which is yet to get a vehicle on the road.
The facility is "something more than an ordinary 'assembly line,'" according to its announcement, and will include three million square feet (280,000 square meters) "for passionate creators and diligent visionaries, where new concepts will be refined and implemented."
It will create 4,500 jobs in the region -- the same area where Tesla is building a major new battery manufacturing facility.
