Is Uniswap a US company?

Could you clarify for me if Uniswap is indeed a company based in the United States? I've been reading a lot about decentralized exchanges and Uniswap seems to be one of the most talked-about platforms. However, the information I've found hasn't been entirely conclusive about its geographical location. Given the decentralized nature of cryptocurrency, I'm wondering if Uniswap's operations transcend national boundaries, or if it has a specific headquarters in the US. Could you please shed some light on this matter? Your insight would be greatly appreciated.
