Herndon; 600 employees
While some federal contractors saw revenues drop in 2014, this software firm’s sales increased by 50 percent. Despite a growing staff—MicroPact merged with Iron Data Solutions in August—employees say management has done a great job keeping everyone connected, creating a culture of trust and collaboration. Project wins are celebrated, new hires are welcomed with an ice-cream social, weekly “shout-outs” recognize good work, and staffers are treated to free breakfast on Thursdays and pizza on rainy days.
Perk: Liberal telecommuting—90 percent work from home at least once a week.
