Apple Inc.

AAPL

Apple is among the largest companies in the world, with a broad portfolio of hardware and software products targeted at consumers and businesses. 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.

CTAS logo

Cintas Corp

CTAS

Cintas has roots dating back to 1929, when the Farmer family cleaned and resold dirty rags to manufacturing plants in Ohio. The firm has expanded its business organically and through acquisitions, and today Cintas acts as a one-stop outsourcing partner for businesses. Cintas will design, manufacture, collect, and clean every employee uniform for a small weekly sum, taking on the upfront capital expense itself. At the same stop, Cintas can also replace soiled or depleted mats, mops, trash liners, towels, first aid supplies, fire extinguishers, and cleaning products. Businesses value an outsourcing partner like Cintas as it simplifies operations and leaves noncore tasks with high regulatory standards in the hands of professionals.
