Transition Global is led by Unity Technologies co-founder David Helgason, who brings large-scale gaming and infrastructure experience into climate venture investing, and uses the Stockholm Resilience Centre's Planetary Boundaries framework as its core impact lens—investing only in companies that can materially improve at least one planetary boundary without significantly harming others. The firm stays at Seed and Series A but actively avoids science-risk and extreme capital intensity by investing only once core science is largely de-risked and looking for business models where heavy capex can sit on partners' balance sheets.
