Threadless is an online retailer that specializes in selling artist-designed t-shirts, hoodies, and other apparel. The company was founded in 2000 by Jake Nickell and Jacob DeHart and has since grown to become a popular destination for unique and creative clothing. Threadless operates on a crowdsourcing model, where artists submit designs and the community votes on which ones to produce and sell. The company has also expanded into other product categories, such as phone cases, wall art, and home decor.
