What country is Coinbase from?

Could you please elaborate on the origins of Coinbase? I'm curious to know which country this renowned cryptocurrency exchange platform hails from. Coinbase has become a household name in the world of digital currencies, but I'm not entirely sure of its geographical roots. Does it originate from a tech-savvy hub in Europe? Perhaps a financial epicenter in Asia? Or is it deeply rooted in the Silicon Valley culture of the United States? Clarifying this detail would help me better understand the context and potential influences behind Coinbase's success.
