Circonomit Tech Stack

Decision infrastructure platform using semantic graphs and distributed data processing

Software Development Cologne, North Rhine-Westphalia 2–10 employees Founded 2022 Public Company

Circonomit is a two-year-old German company building decision infrastructure for financial and sustainability optimization. The tech stack—TypeScript, Python, Scala, Neo4j, JanusGraph, RDF/OWL, Apache Spark/Flink, dbt, dlt—reveals a focus on semantic knowledge graphs and distributed compute: the graph DB choice (Neo4j + JanusGraph) and RDF/OWL ontologies signal reasoning-layer ambition beyond traditional BI. Active projects (semantic modeling platform, graph-based reasoning, LLM-driven workflows, data lineage) and documented challenges (knowledge graph ontologies, semantic backbone development) confirm they are building out a semantic query layer on top of distributed pipelines.
