Infrastructure for KnowledgeStability & Continuity
Sapienstream is not just software — it is infrastructure. A platform built of extraction agents, a community product database, configuration canvases, compatibility analysis, an AI orchestration brain named Nelo, a comprehensive knowledge graph, and an ontology engine. Everything engineers need to stop being human compilers and start building resilient knowledge systems.
Our Story
Why We Built ThisSapienStream was born from a simple frustration: engineers spend more time being human compilers — crunching, seeking, remembering where the right piece of data is — than actually engineering. Our founder, Alex Hofmann, spent years as a controls engineer watching the same pattern: hours of detective work across scattered notes, filing cabinets, OneNote tabs, and conversations that never made it to documentation.
Then there's the Klaus Problem. The 65-year-old senior engineer who knew everything about every line, every configuration, every workaround — and took three decades of institutional wisdom with him when he retired. The knowledge of talented engineers that leaves for other positions. The secret sauces. The solutions to the 3am calls from junior engineers.
The insight was clear: knowledge, as a valuable asset, needs to be mined aggressively and saved in organized, accessible states that are built to be resilient. Engineers don't need another parts catalog — they need a system that acts as librarian and ghost writer in one. One that captures everything, always knows where it is, and saves time and cognitive load at every step.
That's what SapienStream does. Deep Perception™ deploys 6 specialized agents to extract everything from any document. The Knowledge Graph maps your facility's real-world component relationships with immutable decision traces. Nelo — our AI orchestration brain — coordinates 14 agents across 6 modalities and 27 tools, with infinite memory in a three-layer architecture that captures insights, leaves notes, and makes analysis of the why, how, and what of every interaction.
Made in Germany. Hosted in the EU. Built by engineers, for engineers.
Our Mission
To eliminate the human compiler problem. Engineers spend 80% of their time on non-engineering tasks — hunting datasheets, cross-referencing specs, remembering where they put that note. Sapienstream's extraction agents, ontology engine, and Nelo do the crunching so engineers can focus on engineering.
Our Vision
A world where facility knowledge grows with every repair instead of decaying with every retirement. Where the global industrial component market speaks a common language through our ontology engine. Where every decision is traceable, every configuration is captured, and compliance reporting is automatic. A living, explorable knowledge base that is resilient by design.

Our Values
The principles that guide everything we build
Knowledge Continuity
Every decision, every configuration, every interaction — recorded in an immutable ledger. We build systems that create an auditable, tamper-proof record of institutional knowledge.
Engineer-Centric
Built by engineers, for engineers. We understand the frustration of being a human compiler — crunching PDFs, calling vendors, deciphering legacy systems — because we've lived it.
Configuration First
Configuration is the center of knowledge capturing. The process of configuring a machine, a component, a system is where knowledge transfer happens. We don't just find parts — we capture the why behind every setting.
