About

Rithum is an e-commerce operations software company formed from the 2022 combination of CommerceHub and ChannelAdvisor, which rebranded as Rithum in December 2023. Its platform lets brands and retailers manage product listings, inventory, order routing, fulfillment, and performance reporting across hundreds of marketplaces and sales channels from one place. The company says more than 40,000 brands and retailers use it, including Walmart, Home Depot, and Adidas. It is privately held by GTCR and Sycamore Partners and is headquartered in Plano, Texas, with offices in London, Dublin, Madrid, and Melbourne.

It covers both sides of third-party commerce in one network: the dropship and supplier-onboarding tooling that retailers need and the marketplace listing, inventory, and retail media tooling that brands need, across 600+ marketplaces.
