Josh Payne's AI startup, Nscale, has raised $2 billion from Nvidia and other investors, valuing the business at $14.6 billion. The company's partnership with Norwegian industrial conglomerate Aker, Øyvind Eriksen, led to a deal to develop data centers together and Eriksens joined the company's board. This partnership helped Nscale become one of the fastest-rising companies in the artificial intelligence infrastructure boom. The investment underscores the increasing investment in companies building the computing systems required to run modern AI models.
