CDW Headquarters & Corporate Office

About CDW

CDW was founded in 1984 by Michael Krasny after he sold a used computer through a classified advertisement and recognized the growing opportunity to sell technology products directly to businesses. The company originally operated as MPK Computing before adopting the CDW name, short for Computer Discount Warehouse. It expanded from computer hardware sales into software, services, cloud infrastructure, cybersecurity, data-center solutions, digital workplace technology, and large-scale IT consulting.

Today, CDW Corporation is a leading multi-brand provider of information technology products, solutions, and services to business, government, healthcare, and education customers. The company works with more than 1,000 technology brands and supports approximately 250,000 customers. Its offerings cover hardware, software, cloud, hybrid infrastructure, security, digital experience, professional services, managed services, networking, data center, artificial intelligence, and other enterprise technology requirements. CDW reported approximately $22.4 billion in 2025 annual net sales.

CDW remains an independent publicly traded company listed on Nasdaq under ticker CDW and is a member of the S&P 500. The company has expanded internationally through organic growth and acquisitions, including businesses that strengthened its cloud, services, cybersecurity, and enterprise technology capabilities. CDW reported approximately 14,800 coworkers worldwide at the end of 2025, including about 11,200 in the United States and 3,600 internationally.
