Thirdlayer

Thirdlayer builds infrastructure for what it calls the agentic enterprise. Its platform captures a company's decisions, data and operating logic and turns them into structured context that both AI agents and human teams can use. The pitch is that systems of record store what happened, while agents also need the decisions, handoffs and judgment behind each outcome to act reliably. The product has two main parts. Nexus is the enterprise context engine, a living graph of the people, companies, projects, relationships and events an organization works around. It records company knowledge such as processes and precedents, provides a timeline of what changed or is blocked, and supports multiplayer permissions so context moves across teams without breaking access boundaries. A Nexus SDK is marked as coming soon. Dex agents run on top of that context. They include shared agents that automate work for a specific team, custom AI native internal apps that use the organizational graph as a backend, and reusable team skills and tools that encode how a team operates. Consequential work pauses for human approval, and every edit, rejection and override feeds back into the system as learning. It is aimed at companies deploying agents across customer, hiring, project and partnership workflows. Pricing is not published. Prospective customers are directed to book a call.
