Threadless ( Skinny CM Holdings)

Threadless (operated by Skinny CM Holdings) is an online design community and print-on-demand apparel marketplace founded in 2000 in Chicago. Artists and designers submit artwork, the community scores and votes on submissions, and winning designs are printed on t-shirts, apparel, wall art, home goods, and accessories sold through the site. Threadless also runs Artist Shops, free hosted storefronts that let independent creators sell their designs on a print-on-demand basis without holding inventory. Surfaced as a portfolio company of Insight Partners and added to the API Evangelist network for enrichment; no public developer API surface was reachable during this pass (the storefront aggressively blocks automated access).

Threadless ( Skinny CM Holdings) is profiled on the APIs.io network. Tagged areas include Company, Consumer, Apparel, E-commerce, and Marketplace.
