Aleph Alpha is a German AI company, founded in Heidelberg, that builds specialised sovereign language models and the solutions around them for organisations with strict requirements about where data lives and who controls the model. Its positioning is explicitly European: the promise is AI performance that the customer owns, adapted to its context, rather than a generic hosted model that processes everything outside the organisation's control.
The stack is organised in four layers. Models are specialised sovereign LLMs, with Kolibri presented as the flagship sovereign model for business-critical environments, available through an API. Solutions apply those models to concrete domains such as knowledge work, document analysis and administrative processes. The platform provides a sovereign base for developing, scaling and optimising secure AI solutions, and services bring forward-deployed expertise to plan and run deployments inside the customer's organisation.
Aleph Alpha publishes measurable outcomes from customer work — an AI assistant for a public authority used by 80,000 staff, AI agents extracting verifiable insights from sensitive documents at a global chipmaker with a claimed 90% reduction in search time, and AI support in a supplier's requirements engineering that sped up RFQ processing by 40%. The company also maintains an active research and engineering blog covering reasoning, tokenization and reinforcement-learning infrastructure, and is headquartered across Heidelberg, Berlin, Bayreuth and Munich.
