Investment thesis

Tripple pursues a fully impact-oriented approach, using both investments and grants to address real-world social and environmental problems. Guided by planetary and social indicators, the firm concluded that a 100% impact portfolio is the only viable path for the future of investing. It positions itself as a model for what an investment company can look like in a new economy, backing opportunities that solve genuine problems and create value in a changing world, and pairing capital deployment with grantmaking and philanthropy across issues such as tax fairness, housing, migration, and First Nations climate justice.
