The Gephi Consortium

Leading Gephi development

About Us

The Gephi Consortium is a not-for-profit corporation created to join the efforts of industrials, laboratories and civil society in building Gephi, an open source software for network visualization and analysis. The Gephi Consortium has officially started on October 1st, 2010.


What have research laboratories, big data companies and human societies in common? The recurrent need to map and understand complex phenomenons, revealing patterns and trends in relational data. The knowledge discovery process faces now with the “data deluge” problem provocatively emphasized by Chris Anderson on Wired Magazine… and everyone is becoming concerned by mining data/information from the flow. Most of the data can be expressed as networks: transportations routes, power grids, emails, food webs, interlocking directorates or the relations between scientific papers are just a part of their applications.

The Gephi project aims to tackle this underlying complexity by giving the power to visualize, filter and manipulate every kind of networks in real time. A generic infrastructure and long-term vision are the keys to overcome these challenges.

Since we started in 2008 in France, many individuals, students and companies already downloaded and tried Gephi. Sign of good health, we federate engineers and reseach scientists from many different countries.

But the project needs fundings and leadership to comply with these plans. This is the purpose of the Gephi Consortium.


The Gephi Consortium is a not-for-profit organization exempt from income taxation under the French law of July 1st, 1901, equivalent of the United States 501(c)(3) organization. It is governed by its Board of Directors.


Running since October 2008, the Association provides a legal entity to support, protect and promote the Gephi project. Supported alternatively by Association WebAtlas, Linkfluence SAS and SciencesPo Medialab, the initial contributors Mathieu Bastian, Sebastien Heymann and Mathieu Jacomy have progressively set up a global community of users and contributors, notably by participating in the Google Summer of Code internship program. Read this interview to discover the origins of the project.
