Is ICON a real company?

Could you elaborate on the authenticity of ICON as a company? I've heard of it in the context of cryptocurrency and blockchain technology, but I'm curious if it truly exists as a legitimate corporate entity. What is the background of ICON? Are there any official documents or registrations that confirm its legitimacy? Additionally, how does ICON operate within the crypto ecosystem? Does it have a physical presence or is it purely digital? Clarifying these details would help me better understand the validity of ICON as a company.
