Ecosia Ditches Mistral for Open Models: What It Means for EU Startups

Jan de Vries · 2026-10-09

Ecosia, the Berlin-based search engine known for its environmental mission, recently made waves by dropping French AI darling Mistral. But here's the thing: it's not about turning to China. It's about choosing open models that are cheaper, greener, and more flexible. In an exclusive chat with EU-Startups, founder and CEO Christian Kroll set the record straight. So, what's really going on? Let's break it down. ### The Real Reason Behind the Switch Kroll explained that Ecosia's move isn't a geopolitical statement. Instead, it's a practical decision. Open models like Alibaba's Qwen, Z.ai's GLM, and Moonshot AI's Kimi offer lower costs, greater flexibility, and reduced energy consumption. That last point is huge for a company that plants trees with its ad revenue. "We'll probably be using Melious.ai in future," Kroll said. "Unlike Mistral, this is a European company that offers high-quality, affordable AI inference powered by green electricity." Melious, a German platform, runs on European infrastructure powered by low-carbon energy. This lets Ecosia use internationally developed AI while keeping data processing in Europe. Clever, right? ### What About Censorship Concerns? You might worry about political bias in Chinese models. Kroll addressed that head-on. He said Ecosia can switch to alternative models for sensitive topics, like questions about Taiwan. Plus, the company is actively working to remove political biases from its AI-generated answers. So, they're not just swapping one set of biases for another—they're trying to build something better. ### Mistral's Funding and Sovereignty Questions Kroll also raised eyebrows about Mistral's European sovereignty. He argued that its reliance on foreign investors, especially from the US, undermines its independence. And he's not wrong. Mistral's recent funding rounds tell the story: - September 2026: $3.3 billion Series D led by Samsung Electronics, valuing the company at over $23 billion. - March 2026: $800 million in debt financing for a data center near Paris. - September 2025: $1.9 billion Series C led by ASML. US investors like Andreessen Horowitz, Nvidia, and Salesforce Ventures joined the latest round, alongside European backers like ASML and Bpifrance. Mistral also invested $3.2 million in Italian infrastructure startup Clastix. These deals are part of a bigger trend: European AI infrastructure saw about $6.8 billion in announced financing in 2026, according to EU-Startups. ### Ecosia's Unique Ownership Model Contrast that with Ecosia's own funding history. The company grew largely without external financing, with early backing from German entrepreneur Tim Schumacher. In 2018, Ecosia adopted a steward-ownership structure. That means it can't be sold, and profits don't go to shareholders. Instead, they're reinvested in the mission. Talk about putting your money where your values are. ### The Bigger Picture for European Tech For Ecosia, this switch is about more than just AI models. It's a vision for European tech: instead of depending on individual AI developers, European companies can build competitive, independent services using open models on European infrastructure. > "Rather than depending on individual AI developers, European companies can build competitive, independent services using open models running on European infrastructure." For Mistral, though, this feels like a loss of trust. It's one of Europe's most promising AI companies, and Ecosia's move suggests that even European businesses are looking elsewhere for flexibility and cost savings. ### What This Means for Startups If you're running a startup, Ecosia's decision is a wake-up call. Open models can be a game-changer. They offer: - Lower costs: No hefty licensing fees. - Flexibility: Swap models as needed. - Energy efficiency: Aligns with sustainability goals. And with platforms like Melious, you can keep your infrastructure in Europe while tapping into global AI talent. It's a win-win. So, is this the beginning of a trend? Only time will tell. But one thing's clear: Ecosia is proving that you can be both competitive and principled. And that's a lesson for us all.
