Apple Inc.

Apple's iPhone makes up a majority of the firm sales, and Apple's other products like Mac, iPad, and Watch are designed around the iPhone as the focal point of an expansive software ecosystem. Apple has progressively worked to add new applications, like streaming video, subscription bundles, and augmented reality. The firm designs its own software and semiconductors while working with subcontractors like Foxconn and TSMC to build its products and chips. Slightly less than half of Apple's sales come directly through its flagship stores, with a majority of sales coming indirectly through partnerships and distribution.

The company's mortgage lending operations are split between its direct-to-consumer lending, which sees borrowers accessing the company's lending arm directly through either its mobile app or website, and its partner network where mortgage brokers and other firms use Rocket's origination process to offer loans to their customers. The company has rapidly gained market share in recent years and will also be the largest mortgage servicer in the US following its acquisition of the Mr. Cooper Group.
