Energy & Nuclear is rapidly transforming the way we think about and interact with the world around us. Across Europe, but particulartly in Switzerland, Energy & Nuclear startups are pushing boundaries, fixing problems worth solving, and reshaping the contours of their industry.
As we get into the end of 2023, we've curated a list of the top Energy & Nuclear startups in Switzerland that are making waves. We update this list monthly by tracking activity in our database of 17,000 technology companies in Europe and sort them dynamically using our Seedtable score, ensuring objectivity.

Rankings are calculated using our Seedtable score – a 1 to 100 score that uses quantitative and qualitative data points (examples are money raised or employees over time) to signal the momentum behind a company. A score closer to 100 indicates a company worth watching closely.
