LionBox is a compact AI server that sits in your office and runs a private ChatGPT-style assistant for teams of 1 to 30 people.
Your team uses it from the browser to ask questions, write and work with company documents. Everything runs on the box, so files, chats and documents never leave the building. Nothing is sent to third-party AI services.
Built by Fastapp Development in Bucharest, Romania. Founders Edition: 50 units, 7–13 December 2026, deliveries from late January 2027.

Hi everyone, Alex here, founder of LionBox 👋 We built LionBox for small companies that want to use AI on their own documents but can't (or won't) send that data to a public cloud service. LionBox is a small, quiet server (~100 W) that sits in your office and runs a private ChatGPT-style assistant for teams of 1 to 30 people. Your files, chats and documents stay on the box, inside your building. - Plug & play: connect it to your network and your team uses it from the browser - Access levels, so each person only sees what they should - RTX 5060 Ti 16GB, 32GB RAM - Made by Fastapp Development in Bucharest, Romania 🇪🇺 Founders Edition opens 7–13 December 2026 (50 units), with deliveries starting late January 2027. I'd love your questions and honest feedback, especially if you run a small team that handles sensitive data.
