Squair (Damien Gorse and Louis Le Roy) advised Arlequin AI and its founders on its €28 million Series A funding round.

‍

Having previously advised Arlequin AI on its €4.4 million funding round in 2025, Squair is pleased to once again support Hugo Micheron, Antoine Jardin, and their teams in this new stage of their development.

‍

This exclusively European funding round is co-led by Redalpine and OTB Ventures, with participation from Bpifrance’s Fonds Innovation Défense, existing investors Vsquared Ventures and 10x Founders, as well as Xavier Niel.

‍

Founded in Paris in 2024, Arlequin AI is developing a new artificial intelligence architecture based on topological neural networks, designed specifically for analyzing complex data in environments where information reliability and traceability are critical. This Series A will allow Arlequin AI to accelerate its R&D efforts and continue the international rollout of its technology.

Congratulations to Hugo, Antoine, and the entire Arlequin AI team on this new milestone!
