Yes, Transworld is a franchise. Transworld Business Advisors is the largest business brokerage franchise in the world, with hundreds of offices across the U.S. and internationally.
It operates on a franchise model, meaning individual owners purchase a license to run a Transworld office in their territory while following the company's systems, training, and branding for buying, selling, and franchising businesses.
Transworld itself also brokers franchise sales as part of its services, so it works both as a franchise brand and as a company that helps clients buy into other franchises.
If you're asking about a different "Transworld" (there are several companies with that name, including Transworld Systems, a debt collection agency), let me know and I can clarify further.
