Each year, over 255 million people are affected by natural disasters, leaving them without access to clean water for days. Current relief efforts cannot provide enough clean water to disaster victims in a timely fashion. DayOne Response developed a family-sized water purification backpack with an integrated filter that allows users to collect, store, treat, and transport clean drinking water in just 30 minutes. The product has been deployed in over 20 countries. The team from California Polytechnic University participated in VentureWell’s E-Team program in 2009. VentureWell invested in the company alongside several angel investors in 2013.
