Open infrastructure for agent-to-agent workflow automation.
Deploy natively within Google Cloud or Azure. Zero external dependencies.
A2AC (Agent-to-Agent Communication) is a deterministic semantic memory and orchestration layer for multi-agent systems. It gives isolated AI agents a shared memory state with bank-grade cryptographic audit trails — deployed entirely within your own cloud tenant. Whether your data gravity is in Google or Microsoft, A2AC deploys natively inside your firewall.
The problem: Enterprises run AI features inside each platform separately — Salesforce, Azure, Google Cloud — but nothing connects them. There is no shared audit trail across systems.
The solution: A2AC provides the connective infrastructure. Push expensive AI compute off the CRM, produce shared work records, and validate agent definitions before execution.
