What if the future of clean energy wasn’t just about invention, but execution? For Sujatha Kumar, CEO of Dsider, success in clean tech hinges on more than groundbreaking technology—it’s about empowering founders with the tools to make their innovations viable, scalable, and economically sound.

Through Dsider’s techno-economic analysis (TEA) platform, Kumar is helping startups bridge the critical gap between vision and execution, ensuring they can navigate complex markets with confidence.

In a recent episode of the Energy Tech Startups Podcast, Kumar shared her insights on the growing importance of TEA in the hard tech space. While clean energy innovation promises transformative solutions, the challenge lies in proving both technical feasibility and economic sustainability. Kumar argues that many early-stage founders, especially in fields like carbon capture, microgrids, and renewable energy, lack the necessary financial tools to assess market fit and long-term profitability—a gap Dsider aims to fill.
