Who are Deribit shareholders?

I'm curious to know more about the ownership structure of Deribit, a prominent cryptocurrency derivatives exchange. Could you please shed some light on who the shareholders of Deribit are? Are they a publicly traded company, or do they have a private equity structure? Are there any notable investors or individuals among their shareholder base? I'm interested in understanding the financial backing that supports this platform and its operations in the ever-evolving world of cryptocurrency finance.
