Now, the company designs, develop, manufactures, and sells electronic displays for retailers, digital billboards, scoreboards, sound systems, message signs, and similar products.

Daktronics has been supplying the official digital scoreboards for the Olympic Games for several decades now. If you have ever watched the Olympics, you may have seen some of Daktronics’ products without even knowing it. However, due to the nature of the multimillion and even billion-dollar sponsorship deals that corporations sign with the Olympics organization, the logos of sponsors are more prominent and visible than the manufacturer of the digital scoreboard.

Since the 2000s, Daktronics has also been consulting with the National Basketball Association to help them better chronicle and digitally referee their games. The company created a digital shot clock that helps viewers see the game action more clearly. And, they developed lighting strips that are affixed to the backboard to aid referees who need to judge baskets that beat the buzzer.

Daktronics became a publicly traded company in 1994. The company is traded under the name “DAKT” on the financial trading markets. Daktronics is a large company that employs 2,501 employees and has a 2021 revenue of $482.03 million.

DocuTap (Experity) – 124 employees

DocuTap, now rebranded as Experity, was a software developer that created data management software products for use primarily in the healthcare industry.

DocuTap was founded by CEO Eric McDonald in 2000. McDonald predicted that the paper-regime standard of recordkeeping in the healthcare industry would evolve to become fully digital and accessible via handheld devices back in 2000. However, while McDonald’s ambition was boundless, he was the sole employee in the company at the time.

McDonald spent five years writing DocuTap’s future proprietary code by himself. He didn’t source any investors until 2012. DocuTap offered automated and customizable software tools that helped healthcare workers better organize, integrate, save, and transfer patient records or medical documents. 

At one point, the company increased to 250 employees and had offices in Georgia and Missouri. By 2019, the New York-based private equity corporation, Warburg Pincus, bought DocuTap and a similar software company, Private Velocity, and merged the two into one new company called Experity.

Experity’s data management software products are now used in over 4,000 healthcare clinics in the United States.
