About
ChannelAdvisor is an e-commerce channel management platform that helps brands, manufacturers, and retailers manage product listings, inventory, pricing, and advertising across dozens of online marketplaces and comparison shopping engines — including Amazon, Walmart, eBay, Instacart, Google Shopping, and international marketplaces. Founded in 2001 in Research Triangle Park, North Carolina, ChannelAdvisor was publicly traded on NYSE (ECOM) before being acquired by CommerceHub in a $715 million deal in 2022, creating a combined e-commerce software platform.\n\nChannelAdvisor's platform connects brand catalogs to marketplace product listing APIs, automating the product data transformation needed to meet each marketplace's specific content and category requirements. The platform manages inventory synchronization across channels, repricing automation to stay competitive, and advertising campaign management for Amazon Sponsored Products, Walmart Connect, and other marketplace advertising systems. For mid-sized brands and retailers selling on 5-20 marketplaces simultaneously, this centralized management reduces the manual work of maintaining separate marketplace accounts.\n\nIn 2025, the combined CommerceHub/ChannelAdvisor platform (now operating under the Rithum brand following CommerceHub's rebrand) competes with Feedonomics (acquired by BigCommerce), Salsify, and Syndigo for multichannel commerce management. The marketplace commerce market continues to grow as brands shift from wholesale to DTC marketplace selling. The combined platform serves thousands of brands and retailers, with ChannelAdvisor's marketplace expertise complementing CommerceHub's drop-ship and supplier network capabilities. The 2025 strategy focuses on integrating the two platforms' capabilities and growing the combined Rithum platform's market share.
