Jeff Bezos’ private space firm Blue Origin recently got its first paying customer and will help launch a satellite into space. The company is one of a number of firms looking to commercialize space, where the vision is to have millions of people “living and working in space,” as Bezos puts it. Elon Musk’s SpaceX firm is a little bit further along the paradigm as it has already given piggyback rides to satellites and shuttled cargo to space stations. SpaceX also just got two paying customers for a private excursion around the moon (both get a window seat, we presume). An interesting webinar discusses the valuation angles of these firms, and a lot of it is relevant to any startup visionary company.
