# Xayn (now Noxtua)

> Xayn is a Berlin-based AI company founded in 2017 as XAIN, rebranded to Xayn in 2020 (privacy-preserving search and the Xaynet federated learning framework), and rebranded again in February 2024 as Noxtua AG — Europe's sovereign Legal AI for legal research, document analysis, and drafting. Backed by Earlybird, Global Brain/KDDI (Series A, EUR 10M, 2021) and C.H. Beck (Series B, ~EUR 81M). The company publishes no public API, developer portal, or maintained SDKs today; its open-source era packages are archived.
