## Summary

Arlequin AI, a Paris-based startup founded by Hugo Micheron and Antoine Jardin, has raised €28 million from Redalpine, OTB Ventures and Bpifrance's Fonds Innovation Défense, following a €4.4 million seed round in 2025. The company, which had been developing a data analysis platform called HuDEx, now intends to build its own models based on topological neural networks, positioned as a sovereign European alternative to Palantir. According to the article, Arlequin was working with ministries, Radio France and BNP Paribas in 2025, and now says it has around thirty employees. The entry of the Fonds Innovation Défense, which has €275 million in funding, signals a strategic interest in dual-use security and intelligence technologies, but does not amount to certification or an operational contract.
