Renumics GmbH vs RAGnexus

Renumics GmbH is a Karlsruhe-based industrial AI company that builds systems for analyzing test, machine, and simulation data. They partner with automotive, aerospace, machinery, and pharma teams to move product development toward data-driven, end-to-end workflows.

Their product Onion is an agentic AI assistant for engineering data analysis. Engineers ask questions in natural language to query logging and fleet data, run plausibility checks, detect swapped channels, and generate interactive visualizations without waiting on custom reports from data specialists.

Renumics also maintains Spotlight, an open source toolkit for exploring unstructured datasets including audio, images, video, time-series, and 3D geometry. Beyond software, the company delivers workshops, data readiness checks, proof-of-concept builds, and full custom AI system deployments.

RAGnexus builds private AI assistants for European companies that need answers grounded in their own documents and systems. It connects to the tools where your knowledge already lives, indexes that content into a secure knowledge base, and deploys an assistant your team can query in natural language with cited sources.

The product is designed around data sovereignty. Deployments run on European infrastructure, with options that keep data off third-party model APIs entirely. RAGnexus targets regulated sectors like law, healthcare, and consulting, where confidentiality and GDPR compliance are non-negotiable.

Setup is handled as a managed service. RAGnexus integrates with your existing stack, handles indexing and maintenance, and delivers a working assistant in roughly four weeks for cloud deployments or eight to twelve weeks for fully sovereign on-premises setups.
