CooTek is a Shanghai-based mobile internet company focused on two core product lines: online literature and mobile games, which together account for nearly all of its revenues. The flagship online literature product in China is Fengdu Novel, a free-to-read app offering novels across genres like romance, fantasy, and science fiction. CooTek monetizes Fengdu Novel through advertising and in-app purchases (IAP) rather than charging per chapter. CooTek also operates Fengdu Literature Platform, where authors publish original content that CooTek can license to third parties for adaptation into audiobooks and short videos. In overseas markets, CooTek offers English and Spanish-language reading apps like Readict; overseas online literature has grown rapidly and now represents roughly 80% of total revenues. CooTek's mobile games business includes casual dress-up and interactive story games, and the company has developed an "Interactive Story+" format that blends game mechanics with its online literature content. CooTek generates revenue through advertising on third-party exchanges and IAP, with IAP now the primary revenue driver. User acquisition relies heavily on paid marketing through platforms like AppLovin and Facebook Ads. CooTek's cost structure is weighted toward user acquisition spend and employee costs, with the majority of staff being engineers and product designers. The company operates parts of its China business through a VIE structure, as is common among Chinese internet companies listed overseas. CooTek is incorporated in the Cayman Islands and trades on the OTC Pink market.
