Doumeng is an innovative mobile advertising technology company in China. We provide accurate delivery services to advertisers through advertising networks and provide efficient monetization services for the media. In 2013, we launched the SDK Platform, a pioneer of early mobile advertising platforms in China. In 2015, we launched a 7-in-1 SDK, which greatly reduced the size and integration efficiency of media embedding in various advertising formats. In 2015, we launched a cloud-supported SDK. After media developers embed the advertising SDK, there is no need to update the SDK; the cloud will automatically update and download the latest code version. In 2017, we launched interactive advertising technology, which perfectly combines advertising, media monetization, and user experience. In 2018, we launched applet advertising technology, adding a new advertising model to the WeChat ecosystem.
