They say everything is bigger in Texas, and that’s certainly true when it comes to the state’s sprawling tech scene. And while Austin may be known as the state’s fastest-growing tech hub, Houston holds its own when it comes to tech potential. As the home of many of the nation’s leading aerospace and energy companies, the Bayou City is no stranger to the tech space. According to the Greater Houston Partnership, the city ranks 12th in terms of tech employment among the nation’s 46 largest metros, outpacing established tech hubs Philadelphia and Minneapolis. And it seems Houston’s increasing popularity among talented tech professionals may be the result of the city’s reasonable living costs. When compared to a city like San Francisco, Houston proves to be the better economic option for many tech companies, which has resulted in a fair amount of California expats setting up shop in the city, according to a report from the Houston Business Journal

Given Houston’s tech prowess, it’s no surprise the city is home to the headquarters of many industry giants. Houston’s collection of leading tech competitors spans a wide range of sectors, from telecommunications to financial services. While one is developing new ways to help companies solve complex IT challenges, another is transforming the selling process within the digital economy. For these tech behemoths that call Houston home, making an impact on people’s daily lives is integral to transforming the city’s tech landscape. Here’s a look at 15 of the largest tech companies in Houston making their mark on the city’s tech scene.
