The Peer Water Exchange Family

Rajesh Shah

PWX is the first social entrepreneurship project that requires changes across the philanthropic value chain: from the funding (foundations and donors) to the grantee (implementers) end. Rajesh conceived PWX in 2003 when given the task of overseeing the funding and managing of water projects for Blue Planet Run Foundation. Rajesh immediately saw the problem of scale: how to deliver thousands of small projects and verify their impact?

He designed PWX to solve the project selection, funding, and monitoring problem facing the foundation. Rajesh got Sapient to develop the first release and has been building on that foundation for five years: designing new features, continually enhancing the platform, developing the partner network, and coordinating all activity on PWX. Managing all of BPR's program activity means being a user of the system and process too.

In Bangalore, he has designed his home to be water efficient and energy efficient, trying to be self-sufficient for water and energy. He also is involved in designing, managing, deploying, and redesigning water, sewage, treatment, and water reuse projects in his community. The technology and the people issues are both challenging and fascinating for him.

His work as a management consultant to companies and non-profits on using internet and e-commerce technologies to change culture, operating models, and market strategies helped in trying a new approach to solve the scale problem in managing thousands of grassroots water projects. His early career spanned 10 years at Bell Laboratories, experiencing all facets of product cycles. After receiving his MBA, Rajesh became a management consultant at CSC Index and also had stints in three start-ups. He moved to the NGO sector, starting by consulting with the Tides Foundation and eGrants' DonateNow and EmailNow services. He served as CTO/CFO at The Natural Step and Redefining Progress. Rajesh helped develop TNS' sustainability advisory services and corporate footprints and global warming mitigation opportunities at RP.

Extremely interested in sustainability and social equity, Rajesh teaches and writes on various issues facing humanity, and is now immersed in the world of water.

Rajesh did his undergraduate studies in engineering at the Indian Institute of Technology, Bombay and Lafayette College, and received an MS and MBA from the University of California.

The Parent — Blue Planet Run (Blue Planet Network)

The idea of creating a run around the planet hit Jin Zidell in 2001 and he founded Blue Planet Run. BPR soon realized that without solving the scale problem, increased funds for water were not going to be used effectively. So BPR was paused until Rajesh came up with the idea of PWX. BPR's support helped create the platform.
