The buyers went agentic. Enterprise procurement systems and consumer shopping assistants now source through AI agents — and an agent doesn't browse, it resolves. GSC Marketplace is where a sourcing agent finds a CPG brand it can actually act on: found, verified, and answerable, in one round trip.
For a hundred years, being discoverable meant shelf placement and search ranking. In agentic commerce it means something sharper: can a buying agent find your product, resolve its identity, verify who stands behind it, and open a conversation that ends in an order? Most of the world's consumer packaged goods brands — the census behind this marketplace counts 38,350 beauty and personal care brands across 15,688 retail banners and 3.29 million points of sale (cpgknowledgegraph.ai) — will never build agent infrastructure of their own. They don't have to. That is the entire point of this marketplace.
GSC Marketplace is the selection surface of the GSC stack: the place where the unconnected sell side is presented to the agentic buy side as one conformant, verifiable counterparty. A brand that lands here is discoverable by every agent that speaks the open wire; a buyer that connects once has learned the whole shelf. Operated by GreenCore Solutions Corp.

Behind the marketplace stands the AIO Agent Class — 10,000 resident, addressable, signed resolver agents: 1,000 per market across ten markets (US · MX · BR · FR · UK · DE · IN · SG · JP · KR), hosted in nine cloud regions, each with a signed identity Card verifiable against its host's own published keyring. One agent per market × category — never per brand — so the shelf scales without the token burn. Directory: aio-registry.ai.
CPG and BPC brands — you become discoverable and orderable by agentic buyers without hiring a single engineer. The marketplace carries your record; the agents answer for it.
Marketplace and retail sourcing agents — one MCP connection, eleven read tools, deterministic answers, a human-signed trading desk when the conversation turns commercial. No key for public reads. No payment machinery in your way.

A marketplace sourcing agent calls, and leaves with a brand it can act on — found (search_brands), verified (GSC-registered identifiers only, resolved live against the CPG Knowledge Graph), and answerable: Instant Agent Message for agent-to-agent lodgement (instantagentmessage.ai), or the human-in-the-loop GSC Trading Desk (gsc-navigator.ai) when a commitment is on the table. Machines lodge; humans decide; every order carries a human signature.

Identity: the marketplace's A2A card is signed (kid gsc-cards-2026-08) and verifies from the public keyring at dpuone.ai; estate facts resolve at gsc-registry.ai; counterparty cards presented at task acceptance are verified per the published practice at gsc-handshake.ai.
Resolution: live against the CPG Knowledge Graph (kg.js); the marketplace holds no graph data. Only GSC-registered identifiers are ever published.
