Highway to success
cnr s - u pmc laborato i re d ’ i n format ique de par i s 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.

3 steps
1 Research for your own use: fix something which is scratchingyou.
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 writeanother 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 monthsWho: Mathieu Jacomy
Development
• Don’t care about re-usability: go fast, use, iterate until anovel approach to the problem of network explorationemerges.
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 monthsWho: Mathieu Bastian + Sebastien Heymann
Development
• Trash everything, write source code from scratch with thefinal 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 Twitteraccount. 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 farWho: the team (44 people so far)
Development
• Trash everything, write source code from scratch with the realissues in mind. Make it modular (APIs) for the long-term andother 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’sachievements. Meet them. Help users meet and build localcommunities. Engage them to contribute. YOU are the littlehands.Sebastien Heymann — Gephi: An innovative process of design for enhancing innovation — 13 July 2012
