Nucleation’s first two years

Nucleation Capital completed its second full year as a fund at the end of June, 2023. During these eight quarters, we made ten investments and built a portfolio that showcases how we define our thesis. This then begins to answer the question that many people have: How does a nuclear-focused climate venture fund invest into this sector? The answer is presented in the Two Year Report which we have posted below. We have now commenced our third year and, as an "evergreen" fund, we are continuing to raise capital and welcome new investors. If you are an accredited or qualified investor and interested in getting an allocation in our ongoing investments, please let us know.
