An Original Equipment Manufacturer (OEM)is a company that produces parts and equipment that may be marketed by another manufacturer.

An Original Design Manufacturer (ODM) is a company that designs and manufactures a product, as specified, that is eventually rebranded by another firm for sale.

An Original Brand Manufacturer (OBM) is typically a company that sells an entire product made by a second company or including a component from a second company sources as its own branded product. Selling the product of the second company under its own brand just adds a virtual extrinsic value to the product.
