The agentic supply chain

Where selleragentZ fits.

Buyer agents already route spend through / Relay. selleragentZ puts publishers on the other side of that flow — ready to receive, negotiate, and transact.

— Demand

Buyer Agents

DSPs, brand-side agents, and holders of demand routing spend agentically.

— Routing & decisioning

/ Relay

The agentic router & decision-intelligence layer.

— Supply

Seller Agents

Publishers, aggregators, SSPs, and retail-media networks — the supply side of the flow.

selleragentZ is the neutral runtime for governed seller agents — interoperable through open standards, with no proprietary lock-in.

The deal

We handle the runtime.
You bring the business.

Connect your publisher systems, define your inventory and business rules — SellerAgentZ does the rest. No AI engineers. No protocol experts. No custom integrations.

We handle the hard parts.

  • Agent runtime & lifecycle
  • Governance & identity
  • Automated negotiation
  • SSP publishing
  • OMS synchronization
  • Ad server integration
  • Protocols (IAB Seller Agent MCP)
  • Policy enforcement
  • Transaction execution & reconciliation

You bring four things.

  • Your inventory
  • Your products
  • Your pricing
  • Your business rules

All already in your systems. Nothing you have to build.

— Time to live

Days, not quarters.

Bug fixes, security patches, protocol updates, model swaps — handled by us. Roadmap input — yours.

Built on open standardsCompatible with the protocols agentic buyers are already running.
Who it's for · why now

Built for publishers ready to transact with agents, not just dashboards.

For publishers

Direct publishers, publisher aggregators, supply-side platforms, and retail-media networks who want to be on the supply side of agent-to-agent transactions from day one.

  • Premium publishers shipping seller agents against owned-and-operated inventory
  • Publisher aggregators standing up shared seller-agent infrastructure for their networks
  • SSPs and exchanges adding agent-callable surfaces alongside existing endpoints
  • Retail-media networks meeting agentic buyers inside their own programs

Why now

The protocol layer has stabilized, buyer agents are in production, and the build cost for a compliant seller agent is still measured in quarters.

  • The protocol is ready. IAB Tech Lab's Seller Agent MCP (Protocol 2025-06-18) is the published standard — 41 standardized tools, stable transport.
  • The demand is real. Buyer-side agents are already in production and routing spend agentically.
  • The build cost is the bottleneck. Standing up a compliant seller agent from scratch takes 3–6 months of engineering across protocol, runtime, governance, and integrations. selleragentZ collapses that to days.
