In this week’s TOP 100 Public Voting update, three startups that focus on green innovation go for gold: Cleantech startups Perovskia, Daphne Technology, and Synhelion have received the most votes so far! We are about halfway through the voting period, so if your cleantech startup is not among the current top three, fear not! Share your startup.ch voting page with all your friends, employees, and fans, and ask them to vote for you before July 18, 2021. Remember: Everyone with a LinkedIn account has one vote to choose the 10 most innovative Swiss startups.

Every year, the TOP 100 Swiss Startup Award showcases the 100 most innovative and promising Swiss startups chosen by a 100-strong jury of leading investors and experts. The TOP 100 Public Vote runs parallel to the expert jury ranking and highlights outstanding Swiss startups that will be celebrated on stage at the award night on September 8, 2021.

This year, we will honor one Public Voting winner for each of the 10 verticals (biotech, cleantech, engineering, fintech, foodtech, ICT, medtech, proptech, robotics, and security). To keep things interesting, we will provide updates for each vertical separately: Our second update, after medtech and ICT, we now focus on the three cleantech startups that have received the most votes for the 2021 TOP 100 Public Voting so far.



1. Perovskia: Developing digitally printed customizable solar cells
2. Daphne Technology: Reducing toxic pollutants and GHG emissions
3. Synhelion: Producing solar fuels to move the world toward net-zero emissions

The race is still wide open, and you have more than five weeks to get the votes to win! If your startup is eligible to participate, make sure your share your startup.ch voting page with your employees, followers, and friends, and encourage everyone in your network to vote for you.
