Masonite International Corporation is a publicly traded company that specializes in the manufacturing and distribution of doors for residential and commercial use. While the company has a corporate office in Tampa, Masonite has operations in North America, Europe, Asia Pacific, Africa and Latin America. The company was founded in 1924 by William H. Mason, who invented a new type of hardboard material for use in doors and other construction materials. This innovation revolutionized the door industry and ultimately led Masonite to become a leading player in the market. Today, it offers an extensive range of door products, including interior doors, exterior doors, patio doors, and commercial doors. These products are known for their durability, quality, and design versatility, which is a big part of the reason why Masonite stock - creatively listed 'DOOR' on the New York Stock Exchange - trades so well. Tampa has been lucky enough to serve as this corporation's home base for years. Its executive team works out of a location on E. 5th Avenue which connects to a greater global workforce of approximately 10,700 staff.

Primo Water

Primo Water is a leading provider of purified drinking water and water dispensers in North America. They offer a wide range of products, including water coolers, refillable water jugs, and single-serve bottles. Primo Water has been based in Tampa, Florida for a long time, but its specific position within the city recently changed. The company moved from a 15,000-square-foot office on Boy Scout Boulevard to a new $500 million Midtown West development in 2021. Luckily, that's just a proverbial drop in the bucket for a corporation that made over two billion dollars the year prior.
