When Ty Melton first envisioned the smoothly operating, successful business he runs today, he imagined an aquarium. Fish, plants, crustaceans, all harmoniously living together. “I wanted to build a little ecosystem,” Melton says. He had, when he started his Boulder, Colo., company, recently left a job at a cabinetmaker, where he worked 70-hour weeks for low pay. “It was a great company, and I learned a lot,” Melton says, but he didn't want to keep working there. “The idea was that [my company] would be a more fun place to work if the people working for me thought I was a good guy and liked working for me.”
