Massive collective intelligence platform

Massive collective intelligence is the capacity to mobilize communities on a large scale (hundreds and thousands of participants) around key stakes and challenges to co-create new solutions in a short space of time.

Our levers

Enable Conversations

Assembl is a platform that enables conversations, rather than ideas. It recreates, as realistically as possible, the conditions of a debate based on rich content and free expression. Visible to all participants, these conversations take place with maximum transparency.

Use a Modular Design

The consultative process framed by Assembl respects the evolution and life cycle of each idea. This is why the platform is modular and the interface created according to Design Thinking principles to conserve the evolutive nature of the debate.

Draw on Artificial Intelligence

Machine Learning helps categorize the content published on the platform, before it is analyzed and synthesized using human intelligence. A unique algorithm developed in partnership with Inria classifies messages automatically. However, humans have the final say, natural language recognition simply helps process the huge amounts of data.

A Hybrid Approach

The digital experience extends over several weeks and mobilizes as many people as possible. Face-to-face encounters reinforce and enhance this digital approach. They may take the form of co-construction workshops, design fiction sessions e.g. BrightMirror or flash debates led by mediators and ambassadors. All the ideas expressed during these encounters are used to further enrich the platform.


Assembl is a collective intelligence method and technology

Assembl methodology is based on two key elements: establishing different phases to facilitate dialogue and continuously structuring information using digital tools.


Analyzing and facilitating an Assembl debate


  • Identify and extract key ideas during conversations
  • Categorize content to make the information easier to synthesize


  • Produce regular iterative summaries (visual and text) from the debate
  • Deliver a final overview

Knowledge manager

  • Provide data and information to stimulate conversations
  • Check facts to enrich contributions with objective data

Community Manager

  • Identify target populations
  • Motivate the community during the debate
