How the 100-Day Challenges started
At its core, the initiative follows a pragmatic, agile approach: in short, focused development cycles, concrete open-source solutions are created for immediate use in public administrations. This method deliberately contrasts with lengthy large-scale projects, prioritising quick, visible successes.
The three challenges launched in May 2024 focused on critical areas where sovereign alternatives to proprietary solutions are urgently needed: cross-border authentication, AI-powered collaboration tools, and secure document editing.
Through close cooperation between developers and domain experts from both countries, solutions were developed that meet the high technical demands of public administration.
Showcasing the results
The three challenge teams presented solutions that directly address key challenges of digital autonomy:
• Cross-border Single Sign-On (SSO): The first team introduced an SSO integration that allows German government employees to log into the French collaboration platform “La Suite” using their existing credentials—eliminating the need for separate accounts while maintaining security standards. The system is designed to scale and accommodate additional European partners in the future.
