Best Companies

Shine United (Madison, Wisconsin)

In the past five years, this Wisconsin-based advertising agency has shared more than $500,000 in profits with its employees through the company's ShineShares program. The agency partnered with the University of Wisconsin's oncology department to develop the Ride, a biking event that benefits cancer research. Employees also get snacks every day, "Beer Thirty" on Thursdays, and Summer Fridays, a program that lets employees leave at noon.

GroundFloor Media (Denver, Colorado)

The key for workers at this midsize public relations firm in Denver is that employees work anytime, anywhere. Headquarters are in a former warehouse downtown, near Coors Field. The offices are spread around the central space that doubles as a wet bar every Thursday when the company's "bear club" brings in a new brew.

Ergodyne (St.Paul, Minnesota)

The St.Paul-based company has grown to operating out of a retired storehouse with plenty of natural light. Rules about dressing? "Wear something." Its purpose? To create cool, comfortable, and tough safety workwear for those who need it to get the job done. Ergodyne has around 50 employees, who enjoy hot dish cook-offs, tickets to sporting events, and at least one happy hour every quarter.

Southwest Michigan First (Kalamazoo, Michigan)

It's family first at this Michigan economic development advising agency. CEO Ron Kitchens says that in the past year, the company has made a push to go green, initially started by the millennial employees who make up half the agency's workforce.
