Yes, to my understanding the SF office is mainly a sales/business office, while engineering/technical work remains based in Copenhagen, with some bits outsourced elsewhere (Ukraine, China, etc.). I believe the main rationale for the SF office is that it's closer to a number of potential clients and investors (and events like GDC), but operations weren't moved there. If anything they seem to be doubling down on Copenhagen as the engineering site, recently moving to a bigger new space in the city center.
