Channel Advisor

Leading multichannel commerce and marketplace management platform, now part of the broader Rithum commerce network following merger with CommerceHub

ChannelAdvisor, now operating as Rithum following a 2023 rebrand, was founded in 2001 and built its reputation as one of the most comprehensive cloud-based e-commerce and multichannel commerce platforms in the industry. The platform historically enabled brands, manufacturers, and retailers to manage and optimize their product listings, inventory, pricing, and advertising across hundreds of online marketplaces and digital marketing channels including Amazon, eBay, Walmart, Google Shopping, and more. ChannelAdvisor went public on the NYSE in 2013 and was subsequently acquired by CommerceHub in 2022 in a deal valued at approximately $715 million. Following the merger of ChannelAdvisor and CommerceHub under private equity ownership by GTCR and Sycamore Partners, the combined entity rebranded as Rithum in 2023. The unified platform brings together ChannelAdvisor's multichannel commerce and digital marketing capabilities with CommerceHub's dropship and supply chain network, creating a more comprehensive commerce network solution. The combined company serves thousands of brands and retailers globally, processing billions of dollars in gross merchandise value annually. In the AdTech and commerce technology ecosystem, Rithum (formerly ChannelAdvisor) occupies a significant position as a full-funnel commerce enablement platform. Its capabilities span marketplace management, retail media advertising, digital marketing optimization, dropship fulfillment, and analytics — making it a critical infrastructure layer for omnichannel commerce strategies. The platform's breadth of integrations and its data-driven optimization tools continue to differentiate it in a competitive landscape that includes players like Feedonomics, Linnworks, and Productsup.
