Can you set up an umbrella company?

Excuse me, could you please clarify for me what exactly you mean by setting up an "umbrella company"? Are you referring to establishing a holding company or a parent company that would oversee and manage the operations of multiple subsidiary companies? If so, I'd be happy to discuss the process with you and explore the potential benefits and drawbacks of such a structure. Alternatively, if you're referring to a different type of entity, could you please provide more context or specific details about what you're looking to achieve? Thank you.
