Rasa

Rasa Technologies develops open-source conversational AI software that enables developers to build contextual AI assistants and chatbots. The company was founded in 2016 by Alexander Weidauer, Alan Nichol, and Justina Petraityte, and is headquartered in Berlin, Germany.

Rasa's platform consists of Rasa Open Source, a machine learning framework for automated text and voice conversations, and Rasa Pro, an enterprise platform that adds deployment, analytics, and management capabilities. The company's software is used by organizations including Adobe, Airbus, and Deutsche Telekom to build customer service bots, virtual assistants, and automated support systems. Rasa's approach focuses on providing developers with control over training data and model customization.

The company raised $26 million in Series B funding in 2021, led by Accel, bringing total funding to approximately $40 million. Previous investors include Accel, Basis Set Ventures, and Uncork Capital. Rasa has grown to over 100 employees and maintains both its open-source community project, which has been downloaded millions of times, and its commercial enterprise offerings.
