Who owns Upbit?

Could you please clarify who the owner of Upbit is? I understand that Upbit is a popular cryptocurrency exchange platform, but I'm not sure who is behind the company. Is it a publicly traded company, or is it privately owned? Additionally, are there any major shareholders or investors that have a significant stake in Upbit? I'm interested in learning more about the ownership structure of this exchange and how it may impact its operations and decision-making processes.
