Is Bubble a private company?

Could you please clarify for me if Bubble is indeed a privately held company? I've been hearing a lot about it recently and am trying to understand its corporate structure. Is it owned and operated by a group of individuals or entities, rather than being listed on a public stock exchange? Could you also elaborate on any relevant information about its funding, investors, or corporate governance structure, if it's available? Your insight into this matter would be greatly appreciated.
