Connected Solutions Group

In 2005, Michael Pittman didn't know anything about selling used electronic devices. But when the former building superintendent discovered that people were willing to pay good money for refurbished BlackBerry phones, he took a sales job at a reseller. Ten years later, he founded the Mechanicsville, Virginia-based Connected Solutions Group, or CSG, to do more than sell refurbished wireless devices. Pittman's company has also developed a specialty in creating mobile command centers for first responders and others who may need to power up to 168 laptops in a time of crisis. That business has become an entire division at CSG, and with partners like Verizon in tow, it expects to generate more than $26 million in 2019 revenue. --Guadalupe Gonzalez
