Why agentic AI systems fail in production without a semantic layer
Agentic AI systems require a semantic layer (ontology) to ensure deterministic, explainable and auditable operations. Prometheux's ontology engine connects fragmented data sources, automates workflows, and delivers exponential speed gains, as evidenced by customer testimonials reporting 250%+ performance improvements in complex reasoning tasks.
Ontology for Data & AI
Build operational ontologies that process data anywhere it lives. Run your most critical processes on AI built on your business logic.

Process
Power AI
Define Build Ontologies Across Fragmented Data
Define the key business concepts in your organization and the rules that govern them. No GraphDBs, no OWL/RDF, no expensive black-box consulting. Connect any data source to your ontology in one click, Excel, SQL, NoSQL, graph, object storage, without migrations or complex pipelines.

Process Use the Ontology Engine to Automate Workflows
Process data anywhere it lives, read and write to any source, run graph analytics on your existing stack without GraphDBs, and deploy on any cloud with one click. Exponentially faster than PySpark with no vendor lock-in, migrate data and compute across clouds without complex pipelines.

Power AI Data Both Humans and AI Can Work With
Connect agents via APIs or MCP for deterministic data processing with full audit trails at row, column, and value level. Fragmented data becomes shared operational context—humans and AI get the same explainable, repeatable results.

From Our Happy Customers
Senior Director
US Biotech · Rare Disease Space
Prometheux is a Trusted Knowledge and Decision Intelligence platform. Imagine being able to define concepts connected to any source and orchestrate these to solve complex business challenges. In the age of AI and LLMs, Prometheux is a critical tool to ensure decisions are made with proper context, transparency and explainability.
Marco Romei
Deputy CIO · Banca Sella
Generative AI without ontologies is an engine without a road. Prometheux builds the road.
Anna Fava
Former Senior Manager, Data & AI · Dompé
Prometheux is more than just technology; it is a catalyst for fact-based decision-making. The ability to query heterogeneous databases through a flexible ontology makes it possible to infer deep knowledge and automate complex tasks, delivering trustworthy insights that far exceed the capabilities of traditional systems.
Head of R&D
Central Bank
With Prometheux, we achieved a speed-up of over 250% on critical tasks involving complex reasoning over knowledge graphs with hundreds of millions of nodes and billions of edges. In the financial domain, where timeliness and analytical depth are both essential, this level of performance improvement significantly enhances our ability to extract insights, manage risk, and support data-driven decision-making at scale.
Massimiliano Malin
Head of Credit Risk · Banca Sella
Prometheux enabled us to build a system that can access our databases, process all the client’s historical variables, and provide an intelligent, understandable explanation autonomously.
