    OUR VISION

    We build the digital infrastructure for those who design complex physical systems.

    The systems behind today's complex hardware products still rely on disconnected files, spreadsheets and siloed tools. For a regulated, safety-critical product, that isn't a tooling problem. It's an infrastructure problem.

    Absolute trust by design.

    When you read a value in Koddex, you know it's right, structurally guaranteed. Every baseline verifiable, every design decision explainable to an auditor or a regulator.

    Structured, yet malleable.

    Typed objects, explicit relationships, deterministic workflows. But the business logic is yours. You model your own reality, from the 20-person startup to the global industrial group.

    Execution is a craft.

    We remove the administrative noise of chasing versions and rebuilding context, so teams can focus entirely on their mission. Software should extend the craft, not get in its way.

    « Rigor shouldn't be a brake on innovation. It should be the infrastructure that makes innovation possible. »

    « Complex hardware demands a rigorous, regulated methodology. We instill a mindset of flexibility within that rigor, so engineers adapt fast without compromising structure. »

    NUCLEAR & ENERGY · WHAT WE HEARD, NOT WHAT WE ASSUMED

    A reactor programme, a spreadsheet, and one person who knows why the columns are there.

    One reactor, one spreadsheet

    Configuration management for a reactor programme lives in a single spreadsheet. It holds, because the people who wrote it are still there. Nobody has asked what happens when they are not.

    for the configuration of a whole reactor programme

    « We need to get professional about this. »
    Project Director · Nuclear engineering
    When it gets paid forEvery new programme

    How do you answer that today?

    Configuration is a locked structure, not a file someone maintains.

    “Followed artistically”

    No PLM. Each project manager tracks the standards their own way, in their own Google Docs and spreadsheets. Which means nothing is tracked. Finding out what was decided means finding the person who decided it.

    one per project manager, so none

    One model the project manager owns, that every team fills the same way.

    The standard everyone is sure about is the 2015 one

    Standards get revised a handful of times in a career, so people stay confident in the version they learned. Then two thousand units have to be built to it, by technicians nobody trained on the current text.

    The standard is a dated version in the model, not a memory.

    The spreadsheet holds until the person who wrote it leaves.

    PLATFORM OVERVIEW

    One backbone for a structured, traceable and computable product.

    Visual metamodeling

    Build your single source of truth. Define your own component blueprints.

    Graph-level computation

    Automate critical roll-ups. Changes propagate deterministically.

    Lock & revision control

    Secure your baselines. A locked baseline is a structural guarantee.

    End-to-end traceability

    Make your lifecycle audit-proof. Requirements linked to physical results.

    koddex · visual metamodeling
    SHIP ON TIME. EVERY TIME.

    Write the BOM you actually ship, then lock it.

    Define your engineering objects once. Lock the structure for audit. Revise with full traceability without breaking certification.

    Define once, reuse across the whole BOM

    A living tree, every discipline edits the same model. No exports, no version confusion.

    Lock, branch and revise safely

    Freeze a baseline, keep V1 in production, revise V2 on its own branch with zero collisions.

    Certification-ready templates

    RCC-M, IEC 61513, IEC 60880, ISO 19443. Calibrated by sector from day one.

    SEE EVERY IMPACT, BEFORE IT HITS.

    Visualize the full impact of every change.

    A single changed component can affect more than 200 dependencies. Catch every deviation before the commit, not three weeks later.

    Items within items

    Attributes nested at every level, mirroring a real assembly.

    Computation links every attribute

    Mass, size and coefficients linked by formulas. A value never lives alone.

    Catch the deviation before the commit

    An out-of-spec requirement is flagged instantly, the moment a value moves.

    Nuclear, energy, defense. Structured for every safety authority.

    YOUR TOOLS. YOUR AGENTS. ONE PRODUCT RECORD.

    Let AI agents work inside your design record.

    Koddex exposes a Model Context Protocol (MCP) so AI agents read, write and automate inside your system models.

    Native MCP access

    Agents authenticate and receive typed scopes. Every read and write is fully logged.

    The same rules as humans

    Targeted rights on precise entities. The same approval workflow as your engineers.

    Full audit trail

    Actor, timestamp, diff, impact, all logged. No agent bypasses a locked baseline.
