About Dhwani Rural Information Systems
About
Dhwani RIS's journey began in 2012, fueled by a passion for leveraging technology to drive social change. It all started during an internship at the Institute of Rural Management Anand (IRMA), where our founders, Sunandan Madan and Swapnil Agarwal, worked closely with rural NGOs and grassroots organizations. They quickly recognized a significant gap—many of these organizations struggled to integrate technology into their work.
This realization became a mission. They saw the need for a unique approach—one that combined a deep understanding of both technology and the development sector. A one-size-fits-all solution wouldn't work; each organization faced unique challenges. So, they set out to create tailored, context-specific tech solutions to empower these groups, bridging the gap between technology and social impact. This vision became the foundation of Dhwani RIS, where we continue to innovate and drive change.
