The 16 most promising Swiss engineering startups of 2025, according to investors

The 100 most innovative and promising Swiss startups are picked by a panel of 100 leading investors and industry experts and are revealed at the Top100 Swiss Startup Award. This year, engineering has 16 representative startups in the Top100 (including 3 in the Top10). We have also talked with Top100 jury member Andrea Silberschmidt-Buhofer, partner at EquityPitcher Ventures. Learn more about these engineering companies on the frontline of technological advancements.

The annual ranking of the Top100 Swiss Startups has become a benchmark in Switzerland’s startup ecosystem—and beyond. Every year, a panel of 100 leading investors and startup experts chooses the 100 most innovative and promising Swiss startups. Each jury member nominates 10 Swiss startups that are fewer than five years old and show the greatest commercial potential. They assign 10 points for the first place and one point for the tenth place. The companies with the most points make it into the Top100 Swiss Startup Ranking.

Exiting perspectives
The engineering sector is facing several challenges simultaneously: a shortage of skilled workers, rising production costs and increasing demands for sustainability and product safety. Yet these obstacles offer significant opportunities. “An exciting window is opening up for startups with automation solutions,” says Andrea Silberschmidt-Buhofer, partner at Zurich-based venture capital
firm EquityPitcher Ventures.

Both large companies and SMEs are increasingly focusing on and in vesting in Industry 4.0 technology. “Some of our portfolio startups are achieving strong order growth abroad despite geopolitical uncertainty,” adds Silberschmidt-Buhofer. Such successes make the capital-intensive engineering sector attractive even to more cautious investors, as exemplified by former Top100 startup ANYbotics: the Zurich-based company raised USD 60 million at the end of 2024.
