Which country is owner of Coinbase?

Could you clarify for me, which nation holds the ownership rights over the cryptocurrency exchange platform, Coinbase? I'm curious to know if it's based in a particular country that's known for its favorable regulations towards digital currencies, or if it's a multinational enterprise with operations spanning across different jurisdictions. Understanding the geographical location of Coinbase's ownership might provide insights into its operations, regulatory compliance, and potential future expansions.
