KEA is a mobile learning app designed to support law students in exam preparation through short, structured learning units and interactive quiz formats. I worked with the founding team from early concept definition to MVP validation, focusing on product clarity, feasibility, and early market fit under strong time and budget constraints.

Context

KEA was initiated to address recurring challenges in legal education: high cognitive load, fragmented study routines, and low engagement with traditional learning materials. Based on insights from a survey of more than 1,000 law students, the goal was to create a mobile-first product that enables efficient learning in short, repeatable sessions.

The project started with limited funding and a broad, unfocused product vision. In parallel, the team needed to define a technically feasible MVP, choose a cross-platform approach, and assemble a development setup capable of delivering within tight constraints.

Approach

I led the product definition and validation phase with a strong emphasis on scope reduction and decision-making clarity.

Together with the founder, I structured the overall product approach, supported early market and funding considerations, and helped set up a suitable cross-platform development team. To reduce risk early, I facilitated three intensive Design Sprints focused on validating core assumptions before committing to full implementation.

Throughout the process, I translated research insights into concrete product decisions, simplified the feature set, and defined the core learning mechanics. User testing was conducted remotely with students from different universities, allowing rapid feedback loops and informed prioritization without heavy implementation costs.

Outcome

The sprint-based validation process resulted in a clearly focused MVP. User feedback consistently confirmed the value of the “quizcast” mechanic: short, condensed learning units combined with immediate comprehension feedback.

The product scope was significantly reduced while preserving the core educational value. The beta version received positive responses across all user interviews and provided a solid foundation for further development. While early validation signals were promising, the project was later discontinued due to strategic and funding constraints.

Key Takeaways

1. Early scope reduction is critical when building educational products under tight constraints.

2. Design Sprints can serve as an effective decision-making framework when uncertainty is high.

3. Validating core learning mechanics early has more impact than expanding feature breadth.

4. Strategic and administrative constraints can outweigh product validation outcomes in early-stage ventures.
