Builtstop makes cities safer and more sustainable by improving buildings earthquake safety. Our technology, NegSV, provides a non-invasive, cost-effective, eco-conscious retrofit that protects structures, saves lives, and extends building lifespans.

Builtstop develops NegSV, a non-invasive and cost-effective device that reduces earthquake damage in existing buildings. We have validated the technology through analytical studies, numerical simulations, and a scaled shaking-table experiment at ETH Zürich. Our next step is full-scale experiment testing and preparing the device for certification. Our goal is to deliver a practical, affordable retrofitting solution that protects buildings
All four co-founders share a common academic background in civil engineering. Three of them first connected through a European program on seismic safety, which sparked their collaboration. The fourth co-founder followed a more entrepreneurial path but also has strong experience in engineering and business and is the brother of one of the founders. Together, they formed a strong and complementary team whose diverse expertise enables technological innovation for Builtstop.
