The reasoning layer holds AI agents that interpret requests, plan steps and act within set boundaries. The execution layer is workflow automation and integrations, moving outcomes between platforms so nothing stalls in a queue.
Systems of record, typically the CRM, stay authoritative, with AI reading from and writing back to them under rules. The interaction layer covers the surfaces people touch, from chatbots to AI voice agents and receptionists.
Above everything sits governance, which defines permissions, review points and audit trails.
Keeping layers distinct matters because change lands in one place at a time: a new model swaps into the reasoning layer, a new source joins the foundation, a new surface attaches to the interaction layer, and the rest of the stack keeps running.
The table below maps each layer to the Paloren service that builds it.
