    How to start from nothing to 50,000 downloads per release?

    How to start with 5 users to reach 5,000 regular users?

    How to go from a student project to an industrial-quality product?

                                                                                                         We started with no plan.

         1     Research for your own use: fix something which is scratching
               you.
         2     Innovate for you and your small user base. Build a prototype,
               iterate and fail quickly, make noise on the Web.
         3     Dominate your market. Trash your prototype and write
               another software from scratch for the long-term. Focus on:
               scaling (source code), scaling (big data), and scaling
               (dev+user community).

                   Step 1: research (Graphiltre)
    Duration: 6 months
    Who: Mathieu Jacomy
    Development
          • Don’t care about re-usability: go fast, use, iterate until a
               novel approach to the problem of network exploration
               emerges.

    UI
          • Design statement: responsive rendering engine + graph filters
               + no scripting.

    Community management
          • Discuss around you. Find support. Not necessary your mom.

                    Step 2: innovate (Gephi 0.6)
    Duration: 18 months
    Who: Mathieu Bastian + S´bastien Heymann
                            e
    Development
          • Trash everything, write source code from scratch with the
               final vision in mind. Try to code it clean (hint: you will fail).

    UI
          • Take care about usability to figure out real issues.

    Community management
          • Make it Open Source. Build a website, forum and Twitter
               account. Commit early successes. Record a video to go viral.
               Listen to novel ideas, discuss the roadmap. Create a
               (non-profit) company. Stay calm: you’ll be insulted.

              Step 3: dominate (Gephi 0.7+)
    Duration: 30 months so far
    Who: the team (44 people so far)
    Development
          • Trash everything, write source code from scratch with the real
               issues in mind. Make it modular (APIs) for the long-term and
               other developers. The software has become a platform.

    UI
          • Make room for unpredictable usages: design extensibility with
               plug-ins, fix the ”first 30 minutes with Gephi for a newcomer”.

    Community management
          • Build on trust. Acknowledge issues. Communicate on user’s
               achievements. Meet them. Help users meet and build local
               communities. Engage them to contribute. YOU are the little

  • 5. cnrs - upmc laboratoire d’informatique de paris 6 How to start from nothing to 50,000 downloads per release? How to start with 5 users to reach 5,000 regular users? How to go from a student project to an industrial-quality product? We started with no plan. S´bastien Heymann — Gephi: An innovative process of design for enhancing innovation — 13 July 2012 e 5/21
  • 6. cnrs - upmc laboratoire d’informatique de paris 6 3 steps 1 Research for your own use: fix something which is scratching you. 2 Innovate for you and your small user base. Build a prototype, iterate and fail quickly, make noise on the Web. 3 Dominate your market. Trash your prototype and write another software from scratch for the long-term. Focus on: scaling (source code), scaling (big data), and scaling (dev+user community). S´bastien Heymann — Gephi: An innovative process of design for enhancing innovation — 13 July 2012 e 6/21
  • 7. cnrs - upmc laboratoire d’informatique de paris 6 Timeline Dominate the market* Innovate for your Research for your early supporters own pleasure Hello world! 1 regular user 100 regular users 5,000 regular users 0 6 24 54 Months *We are here :-) What people “LOL” “promising” “amazing” said about us: “this is shit: can’t do X” “I want to play with “my wife is using it” “already done 20yrs ago” it, let’s find data” “the reference” S´bastien Heymann — Gephi: An innovative process of design for enhancing innovation — 13 July 2012 e 7/21
  • 8. cnrs - upmc laboratoire d’informatique de paris 6 Step 1: research (Graphiltre) Duration: 6 months Who: Mathieu Jacomy Development • Don’t care about re-usability: go fast, use, iterate until a novel approach to the problem of network exploration emerges. UI • Design statement: responsive rendering engine + graph filters + no scripting. Community management • Discuss around you. Find support. Not necessary your mom. S´bastien Heymann — Gephi: An innovative process of design for enhancing innovation — 13 July 2012 e 8/21
  • 9. cnrs - upmc laboratoire d’informatique de paris 6 Step 2: innovate (Gephi 0.6) Duration: 18 months Who: Mathieu Bastian + S´bastien Heymann e Development • Trash everything, write source code from scratch with the final vision in mind. Try to code it clean (hint: you will fail). UI • Take care about usability to figure out real issues. Community management • Make it Open Source. Build a website, forum and Twitter account. Commit early successes. Record a video to go viral. Listen to novel ideas, discuss the roadmap. Create a (non-profit) company. Stay calm: you’ll be insulted. S´bastien Heymann — Gephi: An innovative process of design for enhancing innovation — 13 July 2012 e 9/21
  • 10. cnrs - upmc laboratoire d’informatique de paris 6 Step 3: dominate (Gephi 0.7+) Duration: 30 months so far Who: the team (44 people so far) Development • Trash everything, write source code from scratch with the real issues in mind. Make it modular (APIs) for the long-term and other developers. The software has become a platform. UI • Make room for unpredictable usages: design extensibility with plug-ins, fix the ”first 30 minutes with Gephi for a newcomer”. Community management • Build on trust. Acknowledge issues. Communicate on user’s achievements. Meet them. Help users meet and build local communities. Engage them to contribute. YOU are the little e 10/21 hands.
