Where is 0x based?

As a cryptocurrency enthusiast, I'm often intrigued by the underlying foundations of various blockchain projects. So, I must ask, where is 0x, a leading decentralized exchange protocol, based? I'm curious to know if its development hub is rooted in a particular country or region, as this often sheds insight into the project's cultural and technological influences. Additionally, understanding the geographic location of its headquarters could potentially offer clues about its regulatory environment and accessibility to talent and resources. Therefore, I'm eager to learn more about 0x's base of operations.
