Building a sustainable future requires more than innovation—it requires intentional capital, visionary leadership, and a willingness to act before the world catches on. Climate-tech in India is no longer just about policy incentives or compliance; it’s becoming a strategic investment opportunity that blends environmental necessity with market potential. From early-stage startups solving for electric mobility and battery efficiency to growth-stage companies scaling proven solutions, the ecosystem is beginning to mature.

India GameChanger spoke to Vasudha Madhavan, the Founder and CEO of Ostara Advisors, who pioneered climate-tech investing in India by turning personal conviction into institutional impact. At a time when climate-tech wasn’t even a defined sector, Vasudha saw an opportunity to align capital with the urgent need for environmental change.

Through Ostara, she built India’s first investment platform dedicated to decarbonization, proving that purpose-led capital can deliver both market returns and planetary benefits. Her early work connecting established companies with innovative startups laid the foundation for a growing ecosystem where strategic partnerships and well-timed funding can accelerate clean technology adoption.

Over the past decade, Vasudha has helped catalyze the transformation of climate-tech from a fringe concept to a mainstream investment theme. India’s policy landscape has evolved, subsidies are being gradually phased out, and the capital environment has matured significantly—particularly with the rise of growth-stage and thematic climate funds. She has also been instrumental in bringing global capital into India, demystifying the market for international investors and curating climate-ready opportunities.
