Your data & AI ecosystems.

Onecub helps you create, develop and govern your data-sharing and AI ecosystems: data spaces, consortia, shared rules and AI agents.

Five levers to build and sustain your data & AI ecosystems.Create. Bring the partners together and fund the project.Unite. Align interests so that everyone commits.Share. Exchange data with confidence, everyone stays in control.Develop. Move from a first pilot to lasting services.Govern. Common rules, proven and revised, down to AI agents.

Data & AI ecosystems in action.

EONA-X

Mobility, tourism, logistics

Onecub helped create and develop EONA-X, the data space for mobility, tourism and logistics. Together we are building Gen4Travel: an agentic AI toolbox, controlled by the industry, so that every player can have its own AI travel assistant.

Onecub’s role in EONA-X
  • Panel “Sovereign AI agents, by and for lawyers” at the Conseil national des barreaux

    Legal Data Space

    Law

    Supported by Onecub since its preparatory phase, it has just launched Avocat+ with the Conseil national des barreaux: the sovereign legal AI of France’s 79,000 lawyers.

  • Group photo of the participants in the second ESA-ESPI Space Data Space workshop in Brussels

    Space Data Space Next

    Space

    With Space Cooperative Europe, Onecub leads the blueprint of the future European space data space, for ESA.

  • Members of the DS4Skills consortium on a Paris terrace

    Skills and education

    The European data space for education and skills is writing its common rules: Olivier Dion contributes, for Prometheus-X, to its governance method and to the review of its rulebooks.

Three complementary areas of expertise.

Discover our services

Onecub connects what is often handled separately: the group’s strategy, its common rules and how they are applied in data exchanges and in the use of AI.

Build.

Bring the right players together around useful use cases and a shared ambition, then fund the project.

Gather and fund

Govern.

Clarify roles, rules and decisions from the start, then evolve them with the group.

Govern the group

Build consortia.
Win major projects.

Onecub brings partners together, structures the project, and writes and coordinates proposals for national and European calls for proposals and tenders.

Public examples: InfrateX, the consortium led by Sopra Steria for the European Commission’s Simpl programme, and Gen4Travel, a France 2030 winner.

Governance you can prove.
And that evolves.

Who decides? Who can access the data? Under what conditions can an AI agent act? Governing a data space also means deciding how AI accesses and uses data.

We help ecosystems turn each objective into a rule, with an owner, a control and evidence, then evolve these rules as uses grow.

Our approach to governance
  1. ObjectiveWhat the group wants to make possible.
  2. RuleWhat is allowed, and under what conditions.
  3. ResponsibilityWho applies the rule and who answers for it.
  4. ControlA human review, a contractual commitment or a technical mechanism.
  5. EvidenceThe record that shows the rule was followed.
  6. ReviewThe rule evolves with use and experience.

Prototype, fictional data

Gen4Travel, EONA-X data space

MyTravelConnect is the traveller’s identity and consent wallet, designed for the Gen4Travel AI assistants in the EONA-X data space. It gathers the trip’s information; the traveller then chooses what an assistant may use, and for how long.

The demo step by step

Cooperate at scale.
Govern together.

  • Create value together.Services that no organisation could build alone, backed by shared governance.
  • Stay in control of data and actions.Governance in which everyone chooses what they share, and what AI agents may do on their behalf.
  • Make autonomous ecosystems cooperate.Shared foundations, open interfaces and governance that respects each one’s rules.
