What companies use EOS?

Could you possibly enlighten me on the companies that utilize EOS in their operations? I've been hearing quite a buzz around this blockchain technology, but I'm still a bit hazy on its practical applications. Could you perhaps provide me with a concise list of some notable firms that have embraced EOS, and maybe even offer a brief explanation of how they're leveraging its capabilities? I'm keen to understand the real-world impact of EOS and how it's shaping the future of finance and business operations. Thank you in advance for your insights.
