Builder Challenge
Industrial Renaissance and Sovereignty.
18 hours to respond to Europe's top industrial problem and build real prototypes — built by the engineers, scientists and designers who will shape the next decade of European manufacturing.
The Challenge : PROVE
Where was this critical mineral mined and processed? Is this material really 40% recycled? Is this product compliant to sustainability regulations?
PROVE challenges builders to make the invisible visible. Using physical and digital identification & authentication technologies, sensing systems or AI, teams will build prototypes that turn unverifiable claims into tamper-resistant proof, across critical minerals, natural resources, ethical and recycling/upcycling supply chains.

For Mentors
Help the next generation of deep tech founders build something real in 18 hours.
Mentors are the backbone of the HackSummit Builder Challenge.
You bring domain expertise, experience and honest feedback to teams who are building under time and ressource constraints.
