Chicago’s legacy of innovation stretches far beyond its architectural marvels and industrial milestones deep into science and technology.
The city has been home to a lineage of STEM pioneers like John Bardeen, a two-time Nobel Laureate whose work on the transistor has become a cornerstone of modern electronics, and Maria Goeppert Mayer, whose groundbreaking discoveries in nuclear physics trace back to the University of Chicago.
This spirit of exploration persists in the city’s contemporary tech landscape. According to Cyberstates, more than 11,000 tech business establishments are located in Chicago.
Companies like Epsilon, Keeper Security, and Home Chef are advancing the fields of marketing, cybersecurity and food technology, respectively. These companies stand out not only for their impactful products and services but because of who’s behind them and how team members are supported.
Together, they contribute to a vibrant ecosystem propelling Chicago’s status as a hub for innovators and entrepreneurs.
