What is a mantle in business?

Excuse me, could you please clarify what you mean by "mantle" in the context of business? I'm not quite familiar with this term as it isn't a commonly used expression in finance or cryptocurrency circles. Is it a specific jargon or a concept related to a particular aspect of business? Could you provide some more context or examples to help me understand it better? I'm always eager to learn about new terminologies and concepts in the field of business, so your explanation would be greatly appreciated.
