Joulium turns energy data into economically actionable decisions — and automatically translates them into money, delivery guarantees and end-customer benefits. Three building blocks interlock: Intelligence, Flex Settlement and JOU.App & Marketplace.

Joulium Intelligence detects early which signals are actually causally connected. Flex Settlement turns that insight into secured, automatically settled trades. JOU.App & Marketplace brings the benefit all the way to the end customer — without partners having to build a platform of their own.
We do things differently.
We do not claim to outperform existing platforms at what they already do well. We offer a structurally different input for decisions — one that existing tools simply do not provide.
The core difference: Most market tools look backward. They identify patterns in historical data and assume those patterns will repeat. Joulium Intelligence measures where information is actually flowing between energy markets right now — in real time. That directional flow is often visible weeks before prices react, giving operators and traders a genuinely different starting point for decisions. Not a replacement for existing tools. A different layer on top.
A concrete benefit for every role in the energy market.
From the municipal utility to the prosumer with a rooftop PV system — every audience gets a tangible benefit from the same platform.
Energy Utility / Municipal Provider
Vetted decision grounds, automated and secured flex marketing, a new end-customer product without in-house development, an extra revenue channel from partner participation.
Aggregator / Flexibility Trader
Trustworthy, automatically secured deals with other market participants, audit-ready settlement.
Analyst / Domain Expert
Understandable, vetted signals and forecasts instead of raw data — early warning instead of hindsight.
End Customer / Prosumer
Via a partner’s white-label app: a concrete euro benefit from their own PV system, daily recommendations, local energy trading, community belonging.
Sales Partner / Merchant
Connection to a modern end-customer ecosystem without building their own technical infrastructure.
Institutional-grade infrastructure. Built to be trusted.
These mechanisms are not a product of their own, but a central part of what customers get for their money — consistently across all three building blocks.
Tenant Isolation
Every customer sees only their own data — technically guaranteed, not just organisationally promised.
Roles & Permissions
From platform administrator down to end-customer access: clearly tiered permissions per role.
Full Auditability
Security- and billing-relevant actions are logged and remain reviewable after the fact.
No Open Self-Signup
New business customers are provisioned only after review — protecting existing customers from uncontrolled third-party access.
Continuous Quality Assurance
Every change to billing- or forecast-relevant calculations runs through an automated check before going live.
Multi-Source Data
ENTSO-E, weather data, SCADA/OPC-UA, CSV and REST via an extensible connector architecture.
API-First Architecture
Django 5 backend, REST API — fully dynamic configuration, everything manageable via the admin dashboard.
PWA · Mobile Ready
Browser or native app, full DE/EN interface, dark-mode first.
Post-quantum secure data exchange — built in-house.
For the exchange of especially sensitive data, PostCypher — our own patent-protected data exchange technology, built by the same team behind Joulium — is available.
PostCypher — Post-quantum secure data exchange platform. Zero-knowledge by protocol architecture.
Patent-protected split transport architecture (EP3291480B1)PostCypher provides hybrid post-quantum key establishment (X25519 + ML-KEM-768, NIST FIPS 203) for secure data exchange. The server never receives plaintext, private keys, shared secrets or message keys — zero-knowledge is enforced by protocol architecture, not just promised. High-Security Mode supports true one-time-pad encryption with offline-provisioned QRNG material.
