Our vision is a global human-centric and decentralized personal data network in which all organizations (public bodies, non-profit, academics, corporates, etc.) aim for interoperability and where personal data can flow easily from one organization to the other under people’s complete control and with full transparency.

Our mission is to empower individuals with their data for a fair data economy.


In today’s world driven by data, we believe that humans have to be at the very heart of our technologies.

In a near-future Artificial Intelligence fuelled by data will but a part of every aspect of our daily lives,

so we need to act fast and put humans in the driver’s seat.

We promote key principles for building a real human-centric and effective data sharing infrastructure:

Shared Governance

Personal data sharing rules should be defined collectively by public and private organizations of all sizes, as well as people. We do not want a privately-owned ‘winner takes all model’.

Open standards and Commons

The Personal Data sharing infrastructure (ethics, business, legal, technical) should level the playing field by relying on open standards and Commons. We promote coordination and mutualization.

Value creation and sharing

Value distribution among all stakeholders has to be a pillar of the infrastructure. Organizations need effective business models and ROI if we want to ensure sustainability.

Trust, transparency, and control

For people to feel that their privacy is truly protected, they need to be able to understand what is done with their data in every circumstance and to be able to control what is happening with ease. The Personal Data Sharing infrastructure has to build trust for the ecosystem.

Separation of powers

Control over personal data should not be handled by services exploiting data. People should be able to be represented by tools (Personal Data Operators), independent of their digital services, to control and share their data.

We signed the MyData Declaration

We follow the MyData Movement human-centric principle for data sharing. MyData Declaration.


We believe that building a Personal Data Sharing Infrastructure is a collective work.

Therefore Onecub has been a leader and active member of multiple initiatives and communities globally for years.


We co-founded the Brussel based association aNewGovernance in 2020, after consultation with the EU Commission and +200 organizations worldwide. Our goal is to create a global governance body for personal data that will organize the cross-sectoral Personal Data Space and help to shape the Personal Data sharing infrastructure.


We work closely with multiple communities including the MyData movement represented in +50 countries worldwide and mentioned in the 2020 European Data Strategy. We promote the human-centric MyData model and values. With our ecosystem, we design the future global infrastructure for Personal Data Sharing. See our paper with the MyData community.


We work with the best worldwide experts in our field at defining the standards we need for the Personal Data Sharing infrastructure: consent with the Kantara initiative; legal model with a group of experts from MIT, Berkley, Stanford; business model with Polytechnique; governance with WTO, OECD, WEF, CIGI, Ada Lovelace Institute, etc.

Public authorities

Since our inception, we have been working with key public authorities at shaping the future of the Personal Data ecosystem. We have been involved with the French CNIL in early discussions on the GDPR right to portability and are still working with them on the sharing infrastructure along with Sitra and the French Caisse des Dépôts. We participated in discussions about the EU data strategy with the EU Commission. We participated in the French and German data strategies.


We have been working with many corporations over the years from incumbents to startups, globally and in every sector (Banks, insurances, healthcare companies, mobility players, retailers, etc.). We discuss the architecture on a regular basis with Big Tech players like Facebook (we spend 1 year in the Facebook garage program), Google, or Microsoft. We work closely with many federations like GS1, Eurocities, OASC, the European banking federation, etc. We rely on the federations to scale up the governance.


We are invited speakers at many conferences globally where we meet key decision-makers of our ecosystem: GPDR +1 year at the Commission of Justice, IAPP Brussels, IGF Berlin, Stanford summit, MyData conference Helsinki, The French Assemblée Nationale, les assises des droits du numérique Paris, etc. We organize conferences with federations, corporations, and Universities regularly.
