Who is RBX owned by?

Could you please clarify the ownership structure behind RBX? I'm particularly interested in knowing who the ultimate stakeholder or parent company is. I understand that in the cryptocurrency and finance industry, ownership structures can be complex and often involve multiple layers of entities. It would be greatly appreciated if you could provide a concise yet comprehensive overview of the ownership hierarchy for RBX, as well as any relevant information regarding its management team and any significant shareholders. Thank you for your time and attention to this matter.
