Transforming Energy & Commodity Trading
We're building the future of data management and AI-powered intelligence for energy and commodity professionals worldwide
Our Story
Born from decades of experience in energy and commodity trading, OpenDataDSL emerged from a simple observation: the industry needed better tools.
The Challenge
Energy and commodity traders were drowning in data. Forward curves, market prices, weather patterns, regulatory requirements—managing it all required expensive systems, complex integrations, and countless hours of manual work.
Traditional solutions were rigid, costly, and built for a different era. Teams needed something better.
Our Solution
We created OpenDataDSL, a specialized platform designed specifically for energy and commodity professionals. Our domain-specific language makes complex data operations simple, while our flexible architecture adapts to how you work.
Now, we're taking the next step with Fusion—bringing AI-powered intelligence directly into your workflow.
