What NXAI does

NXAI GmbH is a private frontier AI research company headquartered in Linz, Austria, founded by Prof. Dr. Sepp Hochreiter (Chief Scientist, inventor of LSTM) and Thomas Meneder, and led by CEO Albert Ortig. The company develops xLSTM, a proprietary recurrent neural architecture that matches Transformer performance at linear compute cost via three innovations: exponential gating, matrix memory with covariance update, and memory-independent update. Building on this foundation, NXAI has shipped TiRex, a 35-million-parameter time series foundation model ranked #1 on the GIFT-Eval leaderboard for both CRPS forecasting and classification, plus an xLSTM Distillation Pipeline that converts quadratic Transformer LLMs into linear-time xLSTM students.

The company monetizes through custom enterprise AI deployments: its engineering team partners with industrial customers in manufacturing, logistics, robotics, and mechanical engineering to deliver solutions targeting predictive maintenance, anomaly detection, demand forecasting, and real-time control loops on edge hardware (PLCs from Beckhoff and KEBA, Raspberry Pi 5, NVIDIA Jetson Orin, and emerging photonic NPUs from Q.ANT). Pricing is not publicly disclosed and contracts are multi-year and bespoke. NXAI also pursues open-source distribution through Huggingface (1.3M+ TiRex downloads since June 2025) and GitHub to drive developer adoption, complemented by active presence at NeurIPS, ICLR, ICML, Hannover Messe, and ISC High Performance.

The company has raised approximately $47.6M across two funding rounds (December 2023 and July 2025) and operates with 11-50 employees, the bulk of whom are researchers and AI/ML engineers based in Linz with deep ties to JKU Linz. Strategic positioning emphasizes European digital sovereignty, sovereign AI for industry, and architectural alternatives to US- and China-dominated Transformer stacks, with a spin-off (Emmi AI) acquired by Mistral in 2025 providing external validation of the research lineage.

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• C3.ai: Enterprise AI software provider delivering pre-built AI applications to industrial customers in manufacturing, energy, and logistics. Comparable to NXAI's industrial vertical focus and predictive maintenance use cases, but at much larger scale and with broader product portfolio.
• Google Research (TimesFM): Google's TimesFM-2.5 is a foundation time series model ranked alongside TiRex on the GIFT-Eval leaderboard. Operates broadly in AI infrastructure and serves enterprise customers across many verticals, dwarfing NXAI in scale but competing head-to-head on the same benchmark.
• IBM Research (Granite Time Series): IBM's Granite time series foundation models compete on the same GIFT-Eval benchmark as TiRex. As a broad incumbent, IBM targets enterprise and industrial AI customers with much greater scale and a wider portfolio.
• Amazon (Chronos / Chronos-2): Amazon Science's Chronos-2 is another foundation time series model benchmarked against TiRex on GIFT-Eval. AWS-scale distribution and broader cloud ecosystem make it a structural incumbent competitor in industrial forecasting.
• Datadog: Datadog offers time series forecasting and anomaly detection for observability workloads, ranking on the same GIFT-Eval benchmark as TiRex. A broad incumbent in monitoring/observability with overlapping forecasting capability for industrial and infrastructure customers.

Others

• Salesforce (AI Research / Agentforce): Salesforce's GIFT-Eval leaderboard and new agentic framework rely on TiRex as a top-ranked model. Acts as both a customer/distribution channel for TiRex and a competitor building forecasting features into its CRM/agent stack.

Emerging players

• Mistral AI: French frontier AI lab that acquired NXAI's Emmi AI spin-off. Builds competing foundation models with a European sovereign-AI positioning similar to NXAI's, and is both a strategic partner and a potential acquirer of additional NXAI research output.
• Uptake: Industrial AI platform focused on predictive maintenance, asset performance and supply chain for industrial customers. Targets the same manufacturing/logistics verticals as NXAI TiRex deployments on PLCs and edge hardware.
• Aleph Alpha: German sovereign AI lab building foundation models with European data residency. Comparable to NXAI in European sovereign AI positioning and government/enterprise focus, though Aleph Alpha focuses on LLM workloads rather than time series/edge.

Direct peers

• Nixtla: Nixtla builds TimeGPT and the open-source StatsForecast/TimeGPT stack for time series forecasting. Directly competes with NXAI TiRex on the same enterprise forecasting workloads and leaderboards (GIFT-Eval), targeting similar zero-shot forecasting use cases.
