Ask it anything and it searches everything your company touches, permissions intact, across Slack, Drive, Jira and the rest; that index is what makes leaving painful. Contracts are custom quotes, commonly around 45 to 50 dollars per user per month with minimums near 100 seats. From Palo Alto at a 7.2 billion dollar valuation, and US disclosure orders can follow that index anywhere.

About Aleph Alpha
Aleph Alpha is a German enterprise AI company from Heidelberg building sovereign large language models for governments and regulated industries that cannot send their data to US clouds. Its PhariaAI platform is designed to be deployed inside an organization's own infrastructure, with a focus on transparency and traceability rather than a black-box chatbot.
Where consumer AI hides its reasoning, Aleph Alpha emphasizes explainability, letting operators trace which sources informed an answer, a requirement for public-sector and compliance use. The stack runs on-premise or in sovereign European data centers, supports multiple European languages natively, and is built to satisfy the EU AI Act.
Key features:
- Sovereign LLMs deployable on-premise or in EU data centers
- Explainability tools that trace answers back to their sources
- Multilingual strength across European languages
- On-premise deployment keeping sensitive data inside your walls
- Enterprise integration for retrieval over private document sets
- EU AI Act alignment for regulated and public-sector use
Aleph Alpha is developed by Aleph Alpha GmbH in Heidelberg, Germany, backed by major European investors and positioned as the continent's answer to OpenAI and Anthropic for sovereignty-critical deployments. Its customers are governments, defense, and enterprises that treat data residency as non-negotiable.
Ideal for European public bodies and regulated enterprises that need generative AI they can run and audit on their own infrastructure.
Why choose Aleph Alpha over Glean?
The decisive argument is data jurisdiction. Glean is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Aleph Alpha removes that overhead. As a Germany-based provider, it operates under EU GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
