Is Uphold located in the US?

I'm curious to know about the location of Uphold. As a cryptocurrency enthusiast, I've heard quite a bit about this platform and I'm interested in its physical presence. Specifically, I'd like to ask: Is Uphold located in the United States? If so, what state or city can I find it in? On the other hand, if it's not based in the US, could you tell me where exactly it's headquartered? Understanding the location of Uphold could give me a better idea of its regulatory environment and potential impact on its services.
