Crowdsourcing ideas through an e-commerce platform like Spreadshirt allows anyone to create, sell, and profit from merchandise ideas without minimum orders. The platform handles transactions, printing, delivery, and customer service. Over 9 million design ideas are in Spreadshirt's database, with only about 1,000 belonging to the company. While crowdsourcing generates many potential business ideas and free marketing through social sharing, it also requires managing the crowds and turning their varied output into a coherent customer experience.
