For years now, there has been a concerted effort by governments, environmentalists, and consumers at large to support sustainability – this means reassessing energy sources, materials used, or new products altogether.  As a result, many high-potential startups are looking to service this growing demand. To do so, many have turned to one of the best ways for young companies to raise capital and achieve their goals – equity crowdfunding.

With that in mind, the following is a running list highlighting some of the highest-potential offerings available to eligible investors on platforms like MicroVentures, Republic, StartEngine, WeFunder, and more.

Access to clean water should be the norm wherever you live.  Kara Water looks to deliver on that through its ‘air-to-water' technology, which it states can provide users with 10L of alkaline water each and every day.  This is achieved through a sleek, floor-standing unit geared towards in-home use, providing the ability for clean-water generation in many communities lacking access.

Valuation$16,000,000Previous Capital Raised$2,035,000
Price Per Share$1.84Campaign DeadlineJune 2, 2024

What Is the Appeal Behind Kara Water?

A major appeal behind this product is its approach to water generation.  Rather than relying on refrigerants or the Peltier effect (e.g., dehumidifiers, atmospheric water harvesters) to extract moisture from the air, which is extremely power-hungry, the Kara Pure is said to rely on a system that leverages desiccants.  Interestingly, the company likens the process to how certain types of beetles found in deserts leverage fundamental forces of science to generate water droplets on their shells.

Aside from its approach to water generation, the very use of Kara Pure has the potential to play a role in sustainability efforts by reducing the number of plastic bottles used and discarded. This issue has resulted in rapidly rising microplastics being found in human, plant, and animal life.

For an investor, the draw to Kara Water is obvious.  This is a product that has the potential to play a role not only in sustainability efforts but also in human welfare around the world.  By doing so through an innovative approach, it stands apart from its competitors, offering an attractive and intriguing product.
