MEGA: Make Europe's Greatest Agent

What is eustella?

MEGA: Make Europe's Greatest Agent

eustella is not just another chatbot. eustella is an agentic AI platform — it doesn't just answer, it acts. eustella completes tasks, connects to your favourite apps, and works proactively on your behalf. Think of it as a modern replacement for Siri, built for the AI age: smart, private, and always in your pocket.

eustella is the secure OpenClaw. eustella gives you the same agentic power — task execution, workflow automation, app integrations — but without the security nightmares. No exposed databases, no malicious plugins, no plaintext credentials. Just a secure, private AI agent hosted entirely in Europe.

eustella runs exclusively on European and open-source AI models. No Big Tech dependencies. No black boxes. No data leaving Europe. eustella is the AI agent that Europeans deserve — and that Europe needs to stay competitive in the global AI race.

The European AI Opportunity

Europe has the talent. It needs the tools.

Europe has 325,000 AI professionals — the same number as the United States. Three of the ten most-cited AI scientists worldwide are European. European founders are behind 25% of all global AI unicorns, with a combined enterprise value of $94 billion. And Europeans use AI more than Americans: 133 million monthly active LLM users in Europe vs. 61 million in the US.

But there is a problem. The most popular AI tools — ChatGPT, Claude, Gemini — are all American. The data generated by Europe's 133 million users flows to US servers, trains US models, and creates value for US shareholders. As the "State of AI in Europe" report puts it: "Europeans consume AI brilliantly, but train the algorithms owned by others."

eustella exists to change that. eustella is the first European AI agent built to keep data where it belongs — in Europe, under European law, for European users. Not because Europe can't use American AI, but because it shouldn't have to.
