Company-first agentic creation.
Agentic First is a map for making company information and agent tools usable by agents. Open Company Information is the separate publishing platform: companies put their facts online in a structured, agent-readable form. The Open Tool Directory tracks the tools, standards, runtimes, protocols, and experiments that make agentic work possible.
Agentic First map
Two open surfaces for agentic work.
Open Company Information helps organisations publish trusted company facts. The Open Tool Directory helps builders find agent-friendly tools and sovereign or European options without pretending they are the same product.
