Capstone International is a boutique investment facilitation firm bridging global capital with sustainable opportunities in emerging markets. Founded by graduates of Durham University with expertise in Sustainability, Energy, and Finance, we specialise in connecting international investors with high-quality renewable energy assets and developers in India and the Global South.

Our mission is to enable a just, profitable, and long-term transition to clean energy by combining strategic insight, rigorous research, and a deep understanding of both policy and finance. We operate at the intersection of sustainability and capital markets—where climate ambition meets economic opportunity.

Capstone International provides a full spectrum of services spanning Market Intelligence, Deal Origination, Financial and Regulatory Due Diligence, Market Entry Advisory, ESG Integration, and bespoke Research Reports. Our team’s analytical discipline, academic depth, and on-ground connections allow us to identify projects and partnerships that align with investor mandates and sustainability goals alike.

With a focus on renewable infrastructure, carbon markets, and cross-border M&A, we aim to position ourselves as trusted advisors to funds, developers, and institutions seeking strategic exposure in India’s clean energy transition.

At Capstone, we believe that sound investments are built on foresight, ethics, and an unwavering commitment to impact. We exist to translate the promise of sustainable development into measurable, bankable outcomes.
