Who owns the polygon group?

Can you tell me who exactly owns the Polygon group? I've been hearing a lot about their blockchain technology and the projects they're working on, but I'm unclear on the ownership structure of the company. Are they publicly traded, or is it a privately held company? Are there any major investors or stakeholders that have a significant influence on the group's direction? I'd love to learn more about the team behind the polygon group and how they're shaping the future of blockchain technology.
