At Susthira Impact Foundation (SIF), our 3-Tier Impact Model provides a structured pathway for transforming innovative ideas into scalable and sustainable development solutions. We begin with Proof of Concept, where pilot interventions are designed using a clear theory of change, contextual analysis, and measurable outcomes. This stage allows us to test solutions, learn from implementation, and refine models based on community needs and evidence.

The second tier focuses on Cascade & Collaboration, where successful models are scaled through partnerships with CSR organizations, government agencies, NGOs, and academic institutions. The final tier, Evidence & Policy, emphasizes rigorous research, impact assessment, and knowledge dissemination to influence practice and policy. By integrating learning at every stage, our 3-Tier Impact Model ensures that interventions are not only effective on the ground but also contribute to systemic change and informed decision-making at larger scales.
