What Rasa Does
Rasa is the leading open-source conversational AI framework, letting engineering teams build and self-host their own AI assistants rather than depend on a managed platform. Founded in 2016 by Alexander Weidauer and Alan Nichol, Rasa is remote-first with hubs in San Francisco and Berlin.
Its open-source dialogue and NLU framework has been downloaded more than 50 million times by developers, and its commercial platform layers generative-AI assistant tooling, deployment, and enterprise support on top for customers including Adobe, Orange, Dell, and American Express. Rasa has raised roughly $83.8 million across multiple rounds from investors including Accel, Andreessen Horowitz, PayPal Ventures, and StepStone Group, including a $30 million round in 2024.
Choose Rasa when you need full control over data, logic, and deployment and prefer to build on an open-source foundation rather than a closed managed platform.
