Channel3 is developing the connected database of every product on the internet, giving developers and merchants API access to a real-time, 50-million-item product catalog. Its technology uses multimodal AI models to match products across retailers, link variants, extract rich attributes and keep information continuously updated, enabling agents and apps to surface the best purchase options and send users straight to merchant checkouts. The platform is storefront-agnostic and offers merchants effortless catalog syncing, affiliate tracking and clean, structured data that adapts as schemas evolve. By handling the complex product-data layer, Channel3 lets developers focus on building frictionless AI shopping experiences rather than on data collection and maintenance. The company plans to expand its engineering team and invest heavily in compute to process billions of tokens so it can scale coverage toward “every product online.” Channel3 is a Y Combinator graduate and is backed by several prominent investors, positioning it to become foundational infrastructure for the emerging “agentic commerce” market.
