Mastory.io, a Bill & Melinda Gates Foundation grantee startup based in Germany and Hungary, approached us to create a cohesive brand identity across all aspects of user experience and communication. Their ultimate goal is to establish a democratic, student-centric educational system that caters to individual personalities, strengths, knowledge, backgrounds, and interests, rather than imposing a standardized approach. To achieve this vision, we embarked on a long-term partnership with Mastory.io, merging our team with their in-house developers to collaborate closely. We began with broad, low-fidelity concepts and iterated through every possible touchpoint, from high-level app layouts and user flows to iconography, motion principles, and communication styles. Rather than relying on traditional handover methods, we opted for an ongoing partnership that enables us to continually refine and evolve the design system while consulting with the Mastory team on a daily basis.
