Arlequin AI Funding News -Paris-based Arlequin AI Secures €4.4 Million In Seed Round

The goal is to tackle the growing problem of disinformation and help restore trust in strategic data insights.

The funding round was led by Vsquared Ventures, with support from 10x Founders (Germany), Kima Ventures (France), Better Angle (France), and several French business angels, including David Meneret (Mill Hill Capital), Arthur Dénouveaux, Éric Le Maire, and former Meta executives Julien Codorniou and Julien Lesaicherre.

“If Europe wants to play a leading role in AI, it must step out of the shadow of American and Chinese giants. It needs to pursue its own strategy,” says Hugo Micheron, CEO and Co-founder of Arlequin AI. “At Arlequin, we’re not building yet another LLM; we’re developing comprehension models that require no training data and are highly resource-efficient. By cutting across the field, we can reach breakthrough innovations faster and at a fraction of the cost. This funding will allow us to accelerate the deployment of our platform and strengthen Europe’s technological independence.”

They’ve built a team of over 20 experts—including researchers, engineers, data scientists, and analysts—to power Arlequin AI.

The company develops sovereign data operations platforms using advanced unsupervised AI models. These platforms quickly process and structure complex, multilingual data to deliver certified, unbiased, and actionable insights.

Arlequin AI is focused on solving three key challenges faced by public institutions and businesses: unreliable and fragmented access to external data, the overwhelming volume of information that exceeds human capacity to analyze, and the spread of manipulated content that threatens the credibility of both institutions and corporations.

According to the World Economic Forum’s 2025 Global Risk Report, disinformation is among the top short-term global threats, with the potential to destabilize political systems and governance.

In response, public and private sectors are projected to invest over €437 billion by 2028 in technologies and strategies to detect, counter, and manage hostile and manipulated content.

Arlequin is developing its own unsupervised AI models to give users complete visibility over any dataset and make it easy to turn insights into action. Its data operations platform boosts large-scale analysis and enhances human decision-making capabilities.

Unlike mainstream solutions, Arlequin’s platform doesn’t rely on large language models (LLMs), prompts, or pre-trained datasets. There’s no black box—its entire technology stack is fully sovereign and 100% auditable.

The platform maps narratives and key players, detects and ranks signals of any intensity, filters out noise, generates reports, builds models, and supports strategic decisions.

This approach helps shorten decision-making cycles, eliminate guesswork, and strengthen detection and response efforts in areas like security, defense, communications, and corporate strategy.

Jardin, CTO and Co-founder, adds: “We combine bold DeepTech ambition with the ability to roll out new, specialised products every six months. Our models work like a medical imaging scanner: you simply input the data, and it reveals its natural structure – giving users instant access to the underlying strategic information.”

Arlequin’s technology is already in use across three European countries, supporting public institutions like ministries and government agencies, public and private media organizations such as Radio France, and major European companies including the BNP Paribas Group.

The company is also forming research partnerships with leading institutions like Princeton University, the University of Santa Barbara, INRIA, and Sciences Po. Designed to be user-friendly and accessible to non-engineers, Arlequin’s platform is highly adaptable and can be applied across various sectors—including financial services (for trend detection, fraud prevention, and due diligence), healthcare, energy and environment (for forecasting and reputation analysis), logistics (for supply chain and disruption management), as well as e-commerce, marketing, manufacturing, and insurance (for improved underwriting and fraud detection).

Maria Juesas Portelés, Venture Partner at Vsquared Ventures, adds: “We live in an era where information has become a currency – just like disinformation. Arlequin combines world-class technological expertise with a unique understanding of today’s geopolitical and strategic challenges. It’s precisely the kind of sovereign technology Europe needs to safeguard its independence and navigate through information chaos.”

The new funding will help Arlequin AI double its R&D team, speed up on-premise integrations, and grow its footprint across Europe and beyond.
