    We are building the foundation for portable water purification systems, to help communities switch to a healthier and sustainable alternative to singles use plastic water bottles.

  • Founder's Story

    After completing my Ph.D., I worked in the industry for a few years to put my engineering skills to use. My job required me to travel quite a bit, and during this period, I naively preferred bottled water to stay hydrated as it felt safe, and I could not dare to drink water from any other source. At that time, there were no complying solutions that could convince me to switch to more sustainable solutions without the hassle.

    One day, I was in India for a short work trip, and as usual, I got bottled water to quench my thirst. To my bad luck, the bottled water I purchased that day from a local store got me very sick, and I wondered how that was even possible. Digging deeper, I found out that the bottled water I had purchased from the local store was tampered, and it's very common in the region I was in. To my surprise, not only is it common in this region but also in many other third-world countries. I was shocked to notice bottled water tampering was affecting tens of thousands of people across the globe annually. During this period, I also realized how single-use plastic was becoming a threat to the environment. And the need for more sustainable solutions was lacking in this category.

    To solve these issues, I researched many alternatives, but most of the answers I found were neither practical nor environmentally sustainable. I decided to use my engineering skills and designed our first product in 2018, and I named it CrazyCap. The reason I named it "Crazy" is because many of the people I shared my idea with were calling it "Crazy", since the cap is purifying water using just light, with no use of chemicals, filtering materials, or a need to boil water.

    And now, this once crazy idea is providing clean & safe drinking water to over 100,000 people!
