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?
