Prototyping fund spring 2025: Show don’t tell, and learn along the way
April 28th, 2025 –noon. Despite the power cut which had just started and thanks to Nova SBE’s generator, the Prototyping Fund Showcase took place as planned at Nova SBE. Many visitors took the time to check out students’ projects and engage with the teams.
The Prototyping Fund is an initiative led by the DESIS Lab @ Nova SBE in partnership with the Haddad Entrepreneurshipl Institute to support students’ ideas that aim to address social and environmental issues. The teams represented several programs from Nova SBE and this year for the first time we were delighted to have other Nova schools represented: Nova Medical School and Nova FCT (Science and Technology). There were eleven projects awardeed Phase 1 funding and two returning projects in Phase 2.
The projects reflected a broad range of themes from upcycling, to health innovation, mental health, education, impact entrepreneurship, and future of work. The prototypes were both physical and digital: from a 3D sanitary product dispenser to a biodegradable gel-based water purifier, a shell-based ceramic paste, a toolkit to develop critical thinking, a card-game, a few websites, apps, and AI-powered chatbots. To learn more about each of the ideas please see below.
Several teams stressed how building their prototypes allowed them to show their ideas to potential users, clients or partners. They realized how showing was more powerful than solely telling.
“When we showed them our 3D printed model, suddenly people understood what we were trying to do” (agora)
“Developing and showing a prototype to potential clients fast was essential to learn quickly.” (PillWeb)
“Testing and refining a prototype allowed us to meet users’ needs”, (H₂iNOVA)
Turning an idea into something tangible that others can react to helps ask questions, refine, understand potential implications and collaborate: that’s prototyping!
We are grateful to the Haddad Entrepreneurship team, in particular Carla Portela, for their support. We thank André Martins and the team at FabLab Lisboa who this year again have supported several projects. We are also grateful to Pedro Almeida, IP & Technology Transfer Manager at Nova FCT for facilitating connections between Nova SBE students and Nova FCT experts. We also want to thank all the mentors who met with the phase 2 projects: Sara Camnasio, Domingo Guimarães, Jorge Lagarto, Catarina Lisboa, and André Martins.

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.

Project.Unfolded
A reflective card game designed for students to build emotional awareness, deepen connections, and improve teamwork – scalable for use in onboarding, workshops, and team projects.
How we built it
Built a printed card deck using thick matte paper via local copyshops; includes colorful illustrations and comes in a compact, portable box (still work-in-progress).
How the prototyped evolved since the 1st cycle
Evolved from facilitator-led workshops to a self-guided card game, printed on matte cardstock locally, designed to enhance students’ personal development.
Top lesson learned
Effective reflection needs sequenced prompts; card format enables self-led depth. Premium materials matter – real demand shows when people are willing to pay.

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.

Detective Mr. P.
Patient navigation solution for cancer patients, that supports them in-person during treatment with administrative and emotional burdens.
How we built it
We designed 6 activities with clues and challenges, to help kids develop different problem-solving strategies, think critically, and collaborate on various approaches.
Top lesson learned
In the pre-prototype Green Thumb Academy, kids (6–10) used creativity, critical thinking, and teamwork to solve problems. Mentors’ guidance was key to their success.

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.
