Learnings from the Spring 2025 Prototyping Fund Showcase

Reshell

Transforms mussel shell waste into an innovative, eco-friendly material used as a component in sustainable ceramic pastes, creating a circular solution for waste and ceramic production.

How we built it
We built the prototype by grinding mussel shells into fine powder with industrial mills, then mixed it with clay and minerals to obtain ceramic pastes, fired for testing.

How the prototyped evolved since the 1st cycle
Our prototype evolved using more advanced techniques, better machinery, and a structured approach. We deepened user interactions to gather targeted, effective feedback.

Top lesson learned
Testing shell-to-clay ratios and shells particle size was key to refining quality; interacting with artists gave us valuable feedback and created interest in the material.

PillWeb

Connects hospitals, pharmacies and health centers to share medicine availability, predict demand and mitigate shortages.

How we built it
We built the browser platform with lovable, to bring the solution to life as quickly as possible. Further we used Supabase and Github.

Top lesson learned
Developing and showing a prototype to potential clients fast is essential to learn quickly. Using AI software tools, helps to implement the learnings easily.

KuzaCollective

Empowers African consultantswith back-office support, skills certification, benefits, networks and vetted opportunities, unlocking their full potential. 

How we built it
We created two versions of the landing page to assess the needs and communicate the value proposition. We also created social media posts to get signups and a pitch deck.

Top lesson learned
Initial idea: match startups/small businesses with shared support. Pivot: greater potential supporting independent consultants to deliver more value than startups.

H₂iNOVA

A biodegradable gel-based water purifier that removes bacteria, viruses and heavy metals, providing a simple and sustainable solution for safe drinking water in vulnerable communities.

How we built it
Developed in the laboratory, designed as small circular discs made from agar-agar and sodium alginate, incorporating nanoparticles and natural oils for better efficiency.

Top lesson learned
The importance of prototyping to test and refine our solution, ensuring it effectively meets users’ needs and performs as intended in the real world.

BridgeWise

Most-easy to use digital upskilling platform for SMEs to expand digital expertise in a targeted and efficient manner.

How we built it
We developed an online presence and digital skill management tool that guides the entire upskilling process from skill gap analysis to governmental funding management.

Top lesson learned
Prototyping isn’t about delivering something low-quality; it’s about refining the first customer interaction until they’re eager to commit.

SOMNO

An AI-powered, voice-controlled sleep companion that guides users from falling asleep to waking up with personalized relaxation, soundscapes, and CBT-based coaching.

How we built it
We prototyped gathering real user feedback, building a software Interface, using voice AI scripts and Wizard-of-Oz tests to simulate sleep coaching.

Top lesson learned
Sleep issues stem from stress & habits. Users want adaptive, voice-based support that feels personal and is non-intrusive.

TabBack Memories

NFC cards that link to customizable digital memory albums. Designed as meaningful physical gifts that connect to personal photos, videos, and messages.

How we built it
We built simple MVPs by printing images, attaching them to NFC cards, and linking the chips to cloud-based albums with customizable digital content.

Top lesson learned
For some people, having a physical object can make the digital memories feel more special and emotionally meaningful.

QUIT.

Smart Vape Pen that reduces nicotine concentration automatically and over time. QUIT also tracks users’ consumption behavior and feeds an algorithm to optimize nicotine cessation.

How we built it
Designed the app layout in Figma and built a prototype using nicotine and non-nicotine vapes connected to an Arduino microcontroller running custom code.

Top lesson learned
Relying on external experts like developers can slow progress—but their input is essential to build something impactful.
