Haoxi is a China-based online marketing agency focused on the healthcare industry. The company helps healthcare businesses, including hospitals, clinics, pharmaceutical companies, and medical aesthetics providers, acquire customers through short video ads on major Chinese platforms such as Douyin, Toutiao, WeChat, and Weibo. Haoxi provides full-service marketing that covers scriptwriting, video production, ad slot bidding, ad placement, and real-time campaign optimization. The company manages campaigns using its proprietary Bidding Compass software, which analyzes historical performance data to automate workflows and optimize bids. Haoxi acts as an intermediary, buying ad inventory primarily from ByteDance's Ocean Engine and billing advertisers on a CPM basis. The company earns the spread between advertiser billings and inventory costs, alongside volume-based rebates from ad platforms. Haoxi secures clients through annual framework agreements, relying on inbound demand and platform referrals rather than an outbound sales force. Its growth strategy focuses on adding healthcare clients, expanding onto platforms like Xiaohongshu, upgrading its software, and launching livestreaming and AI marketing services.
