Summoner - The protocol that lets AI agents negotiate across companies

by•
AI agents today are trapped inside single apps. Summoner lets agents discover, negotiate, and coordinate across companies. In one logistics simulation, 2 agents negotiated 592 shipping decisions and reduced costs by 17.6% — with full decision trace and counterfactual analysis. Think: HTTP for AI agents — but stateful and cross-org.

Hey PH 👋 Kevin here, co-founder of Summoner. We kept seeing the same problem: AI agents work great inside one company… but break down the moment they need to coordinate across organizations. So we built a protocol that lets agents: • Discover each other • Negotiate structured proposals • Sign and verify outcomes • Generate auditable decision traces In a logistics simulation, 2 agents negotiated 592 shipping decisions and reduced costs by 17.6% — while surfacing cost vs SLA tradeoffs in real time. This isn’t another agent framework. It’s infrastructure for cross-org coordination. If you’re building multi-agent systems, I’d love your honest feedback.
