eustella

What eustella does

eustella, operated by AI Newsrooms Technology GmbH (a subsidiary of newsrooms.ai) and headquartered in Vienna, Austria, is a European sovereign AI agent platform launched in 2026. The company offers a mobile-first consumer assistant across iOS, Android, and web that competes directly with ChatGPT, Claude, and Gemini, together with an enterprise/developer Platform (announced June 2026, currently in private beta) that exposes APIs and agent orchestration for businesses in regulated verticals including health, finance, and legal.

The platform is built on a full-stack architecture spanning inference, orchestration, and serving, running open-weight and open-source AI models — Qwen 3.5, Gemma 4, GPT-120B OSS, Mistral models, and Whisper — hosted exclusively on European infrastructure operated by partners such as IONOS. Core features include autonomous agents (Deep Research, Trip Planner, Morning Brief, Watchlist), persistent memory across conversations, customizable personality through a Soul feature, document and slide generation, Groups for shared use, and incoming MCP server connectivity for tool integration. GDPR and EU AI Act compliance is described as built-in from the first line of code, with no US CLOUD Act exposure and no customer data used for model training.

eustella monetizes via a four-tier consumer subscription (Free, Comet at €5.99/month, Star at €17.99/month, Cosmos at €89.99/month) with usage-based metering, distributed primarily through app stores and self-serve web sign-up under a product-led growth motion. Enterprise access is gated through a private beta and email request. The company has signed partnerships with IONOS (infrastructure), Bitpanda (fintech), and Geizhals (distribution), all announced in June 2026. The company appears bootstrapped or self-funded through parent newsrooms.ai, with no disclosed external institutional investment.

Core offering

eustella is a European sovereign AI agent platform that delivers a mobile-first personal AI assistant (iOS, Android, web) for individual consumers and a developer/enterprise platform for building on sovereign agent infrastructure. The system runs exclusively on open-weight AI models hosted on European infrastructure, providing agentic task automation, persistent memory, document generation, web research, and voice transcription under full GDPR and EU AI Act compliance.

Product overview

eustella is a single, unified European sovereign AI agent platform accessible via consumer mobile apps (iOS, Android), web application, and a developer/enterprise platform. The consumer product offers four subscription tiers (Free, Comet at €5.99/mo, Star at €17.99/mo, Cosmos at €89.99/mo) providing tiered access to AI agents, memory, projects, and document capabilities. The product is powered by an ensemble of open-weight AI models (Quen 3.5, Gemma 4, GPT-120B OSS, Mistral, Whisper) hosted entirely on European infrastructure. Key features include autonomous agents (Deep Research, Trip Planner, Morning Brief, Watchlist), persistent memory, customizable Soul personality, Projects for document management, and Groups for collaborative use. A separate eustella Platform (June 2026) targets developers and enterprises with APIs, agent orchestration, and sovereign GenAI infrastructure, currently in private beta.

Direct peers

• Mistral AI: Paris-based European AI lab that develops and serves open-weight language models and offers the Le Chat consumer assistant. Most directly comparable to eustella: both are European, emphasize open-weight models, and pursue sovereign AI positioning against US hyperscalers.
• Aleph Alpha: Heidelberg-based European AI company focused on sovereign, trustworthy AI for enterprise and government clients. Highly comparable to eustella in its sovereignty-first positioning and explicit targeting of European regulated entities.
• Hugging Face: Open-source AI platform hosting community models and serving inference. Comparable to eustella in its open-weight model hosting, multi-model orchestration, and developer/enterprise tooling, though with a different consumer strategy.
• Inflection AI (Pi): Personal AI assistant focused on conversational and agentic support for consumers. Closely comparable to eustella's consumer positioning, though without the European sovereignty wedge.
• Perplexity AI: AI answer engine with a freemium consumer subscription and Pro tier — explicitly benchmarked alongside eustella in its beta survey. Directly comparable as a consumer-facing AI assistant competing for the same European knowledge-worker segment.

Broad incumbents

• Cohere: Enterprise-focused AI platform offering LLMs and retrieval/agents as APIs. Comparable to eustella's Platform/API product targeting verticalized enterprise teams, though serving a global rather than Europe-only customer base.
• Anthropic (Claude): Claude.ai consumer assistant plus Claude API enterprise platform. Directly named by eustella as a competitor and ranked just ahead of it in the beta-user survey, demonstrating feature parity with a much larger competitor.
• OpenAI (ChatGPT): Consumer ChatGPT assistant plus API platform and ChatGPT Enterprise. Cited by eustella as a primary competitor and included in its benchmark survey; serves as the hyperscaler baseline for sovereign-AI positioning.
• Google (Gemini): Gemini consumer AI assistant integrated across Android, Workspace, and Cloud. Explicitly named by eustella as a competitor; large incumbent with mobile OS-level distribution that eustella cannot match.

Emerging players

• Stability AI: Open-source generative AI company behind Stable Diffusion and several language models. Comparable to eustella in its open-weight model focus, though primarily image/generative and without a comparable sovereign consumer assistant.
