The company, called Project Prometheus, is coming out of the gates with $6.2 billion in funding, partly from Mr. Bezos, making it one of the most well-financed early-stage start-ups in the world, said three people familiar with the company who spoke on condition of anonymity because details have not yet been made public.
This is the first time Mr. Bezos has taken a formal operational role in a company since he stepped down as chief executive of Amazon in July 2021. Though he is deeply involved in Blue Origin, a competitor to Elon Musk’s SpaceX, his official title at the space company is founder.
