OpenLazarus builds a company-owned AI operating system with AI teammates that work on the company's own records. Its FAQ states that the code and the data are the company's, which can host with OpenLazarus or take the system elsewhere⁠1Frequently asked questionsOpenLazarus.

Best for: Mid-sized companies that want to own the AI system that runs their operations, with its data, choose their models and keep EU hosting available.

Not the right fit for: Companies that only need a private model endpoint for their developers, or that require a named certification such as BSI C5 or SOC 2 before purchase.

What OpenLazarus offers on sovereignty

Three of its published commitments map directly onto the questions in our main guide. On ownership, the code and data belong to the company. On location, European companies can run on servers in the EU, under EU law⁠1Frequently asked questionsOpenLazarus. On mobility, managed hosting with backups, updates and monitoring can be moved to the company's own cloud whenever it wants⁠2PricingOpenLazarus.

On the model layer, the company can use any model through OpenLazarus's AI router, including frontier, open-weight and custom-trained models, and switch as models improve⁠1Frequently asked questionsOpenLazarus. Each company gets its own instance⁠3AI operating systems comparedOpenLazarus, each AI sees only its own database⁠4OpenLazarusOpenLazarus, and its manufacturing page states that the system runs on a server that is the company's and that every action is logged⁠5OpenLazarus for manufacturingOpenLazarus.

The gaps are on paper rather than in design. The pages we read name no security certification, do not identify the EU data-centre provider and do not state the training terms that apply when a third-party model is used through the router. Buyers with strict requirements should ask for these in writing.

Strengths and limits

Strengths

• Ownership is stated plainly: the code and the data are the company’s, which can host with OpenLazarus or take the system elsewhere.
• European companies can run on servers in the EU, under EU law, and managed hosting can be moved to the company’s own cloud at any time.
• Any model can be used through its AI router, including frontier, open-weight and custom-trained models, so the company is not tied to one model vendor.
• Each company gets its own instance, and each AI teammate sees only its own database.

Limits

• No security certifications (such as ISO 27001, SOC 2 or BSI C5) are stated on the pages we read.
• The pages we read do not name the EU data-centre provider or say whether customer data is used for model training by third-party model vendors.
• Prices are in US dollars, and the company behind it is a US LLC.
• It is not a model vendor; sovereignty over the model itself depends on which model the company chooses.

Choose another option if: You need a model API or GPU capacity for your own developers. STACKIT, OVHcloud or Mistral AI fit that better.

Pricing

Published: plans at $100 or $300 a month including the same amount in AI credits, managed hosting from $150 a month, engineering support from $4,500 a month and a 5.5% fee on AI credits.

Questions to ask OpenLazarus

• Which data centre and provider host EU customers, and which certifications do they hold?
• What exactly is exported if we move to our own cloud: code, data, configuration and logs?
• Which models are available through the router with EU processing, and what are their training terms?
• Who at OpenLazarus can access our instance, and from where?
