- No per-seat fees
Don't share your data
Automate your company without sharing its knowledge.
In 2026, privacy is not an option, it's a must. Cloud AI sends contracts, financials and company know-how outside your office. LionBox processes that work locally, inside your perimeter.
True Plug&Play Device
Connect power and Ethernet, then follow the mobile app. LionBox arrives preconfigured, with no specialist installation or software rollout.
No Data Leaks to Competitors
Keep prompts, documents and company know-how on hardware inside your office, not on systems your competitors may also use.
A hardware asset, not a rental
LionBox is hardware you own, with low and predictable power consumption, rather than another per-seat subscription.
Your company knowledge belongs inside your company.
One network. One shared resource.
One private AI.
Every computer in your business.
Connect LionBox to your office router. Every authorized device gets private AI directly in the browser.
One box, shared power
Your whole team uses the same local AI appliance.

Knowledge on three levels
Everyone sees what they should. Nothing more.
Share knowledge with the whole company, keep team files inside the team and let every employee keep their own files private. LionBox answers each person only from what they are allowed to see.
- Level 1, Company: everyone in the company. Shared with everyone, so every colleague gets answers from it.
- Level 2, Department: only that team. Team files stay in the team. Finance never sees Sales files.
- Level 3, Personal: only that employee. Each employee’s own files and chats stay private to them.

Is LionBox for you?
Who should buy a LionBox?
LionBox is built for teams that want useful AI without trading away control, predictable costs or weeks of infrastructure work. If one of these situations feels familiar, it may be the right fit.

Be one of the first teams to bring private AI in-house.
Assembled in Europe.
Do we need an IT specialist to set it up?
No. Connect power and Ethernet, then follow the mobile app. It guides the administrator through claiming the box, connecting the network, creating team accounts and setting permissions in plain language.
Who maintains LionBox after setup?
The administrator uses the mobile app to check health, alerts, working hours and available updates. Normal daily use happens in the browser, so employees do not need to manage the appliance.
How are models and software updated?
LionBox launches with our own optimized build of Qwen 3.5, tuned in-house for the LionBox hardware. New optimized and specialized models, performance improvements, software updates, new features and new skills come with LionBox+. The first 6 months are included; after that you can renew for 6 months €289 or 12 months €389 + VAT. Without LionBox+, the box keeps running on the last version it received. The administrator app downloads signed bundles and transfers them to LionBox, which verifies each one before installing it. Prompts, documents and private answers are never part of that update path.
How many people can use it at the same time?
LionBox is designed for teams of up to 30 people. Its request scheduler shares dedicated NVIDIA GPU capacity across active users, queues work when necessary and keeps every user session separate. In our measurements, every reply began in under half a second even when 16 people sent a message in the same second.
What support do we receive?
Standard product support is included: email support@lionbox.ai and a person answers within one business day. Final service levels will be confirmed before shipping.
What happens if the hardware fails?
Email support@lionbox.ai to arrange service. Direct purchases include a 24-month limited hardware warranty, with statutory rights additional. Under the Keep Your Hard Drive process, we agree how the data drive stays in your custody before equipment is sent for repair. See Warranty & Returns for coverage and the service process.
What happens when our company grows?
You can expand the number of knowledge spaces and users within the appliance capacity. Larger teams or heavier workloads can add another LionBox, and we can help plan how work and knowledge should be divided.
Is ChatGPT safe for confidential company information?
Public cloud AI tools process prompts on the provider's servers, under the provider's terms. Whether that is acceptable depends on your contracts, your data and your own risk assessment. LionBox takes a different route: prompts and indexed documents are processed on the box in your office, so they do not need to be sent to an external AI service.
Is LionBox GDPR compliant?
LionBox is designed to make GDPR-compliant use of AI easier: AI processing runs locally on the appliance, optional external data flows are controlled by your administrator, and company data does not need to leave your network. GDPR compliance also depends on how your organisation uses the system, so your company remains responsible for its processing. The Security page explains the data paths.
Which countries do you ship to?
Standard shipping is included in the hardware price worldwide. We confirm that your destination is eligible before accepting the order. Outside the EU, import duties and local taxes are not included.
