What kind of company is radiant?

Excuse me, could you please clarify what you mean by "radiant" in the context of a company? Are you referring to a company with a particular reputation, or one that operates in a specific industry? It's not a commonly used term to describe a business entity, so I'm wondering if you're referring to a specific aspect of their operations, branding, or perhaps their impact on the world. Could you please elaborate so I can provide a more accurate description?
