What company sells Celsius?

I'm curious, could you clarify for me who or what company actually sells Celsius? Is it a particular exchange, a brokerage firm, or perhaps a direct-to-consumer platform? I'm trying to understand the distribution channels and the business model behind Celsius, as I'm interested in potentially investing in it. Could you provide me with some insights into how individuals can purchase Celsius and what kind of entities are involved in its sale?
