About 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.

Competitive Landscape
Who Rasa competes with, and how they differ.
Open-source conversational AI framework similar in DNA to early Rasa, but built LLM-agent-native from the start rather than retrofitting LLMs onto a legacy NLU pipeline the way Rasa's CALM does.
1 product reviewed on TopReviewedEnterprise conversational AI specialized for internal IT/HR service-desk automation — a narrower vertical than Rasa's horizontal customer-facing chat/voice platform for banks, insurers and travel companies.
1 product reviewed on TopReviewed
Design-first conversational AI tool aimed at product/design teams collaboratively prototyping voice and chat flows, versus Rasa's code-first platform built for engineering teams at regulated enterprises.
1 product reviewed on TopReviewed
Enterprise contact-center conversational AI platform with deep native telephony/CCaaS integrations, competing directly for the same regulated-industry (banking, insurance) deals Rasa targets.
1 product reviewed on TopReviewed
Enterprise conversational AI platform leaning more no-code/bot-building than Rasa's pro-code CALM approach, while competing for similar large-enterprise contracts.
