Everything at some point has a physical manifestation that can be broken down further and further until we explain things with (according to many physicists) strings. Every thought, idea, dream or lie could be described as neurotransmitters moving between neurons, but that's very rarely the level of detail we use. Yes, corporations have physical manifestations. And if we use a formal or legal definition, you could maybe break that down to some database entry at some government branch or paperwork in a cabinet etc. Very real and physical. But then I could hack the database and insert a new company and fake the paperwork, and arguably the result is not a real company. Or delete a real company and destroy the paperwork, but arguably the company will still exist. If we imagine I could create or delete a company perfectly in all its physical aspects, documents, electronic records, inventory, products etc - but not modify anybodies thoughts or memories -, you would be very clearly be able to tell if the company is "real" or not. If nobody knows about it ("believes" it exists) and nobody works for it, it's not real. The office, machines, computers and a bunch of (fake) employment contracts do not result in anything if nobody shows up. If everybody still believes it exists and just continues to work, they might need a few new staplers and other things, and at some point get the paperwork corrected.
