Rasa

Rasa is an enterprise conversational AI platform that empowers developers to build, deploy, and scale AI agents capable of managing complex, real-world conversations. At its core is CALM (Conversational AI with Language Models), which combines the flexibility of LLMs with deterministic business logic to create reliable, controllable agents. The platform supports text, voice, and omnichannel deployment, with built-in NLU, enterprise RAG, agentic orchestration, and MCP integration for connecting external tools. Rasa Pro adds enterprise-grade analytics, observability, and security for production deployments. Organizations including Swisscom, Autodesk, T-Mobile, and ERGO use Rasa to automate customer support, sales enablement, and internal IT and HR workflows at scale.
