Employees tell us they’re proud that Carfax vehicle-history reports make buying and selling used cars safer. What also drives them: good work/life balance as well as bonuses and incentives. (One member of the sales force each year wins a new car.) And though many companies claim to “work hard/play hard,” Carfax takes it to an extreme: Besides occasional contests at the office putting green or shuffle-puck table, colleagues band together for some intense charitable endeavors, including a 200-mile running relay race and a 100-mile Bike to the Beach for autism. The company hosts new-hire happy hours every month for a reason: It has grown by 20 percent over the past three years.
Perk: Free lunch every Friday.
