Who is Wink owned by?

Can you clarify for me who exactly owns Wink? I understand it's a cryptocurrency-related platform, but I'm not sure about the specifics of its ownership structure. Is it a publicly traded company with shareholders, or is it privately held by a specific individual or group? Additionally, are there any notable investors or partners associated with Wink that I should be aware of? I'm looking to get a better understanding of the company's ownership and governance structure.
