Our first product, EthorCEL®, uses patented "electro-membrane" separation technology (U.S., PCT, and other patents). Our customers are the largest users of water worldwide; companies in wet process manufacturing, such as semiconductor,  disk drive, solar, Printed Circuit Boards (PCB) and pharmaceutical companies. They spend billions making water for use, and then throw it away after one use - this is done continuously, while making high tech products. The existing market for pure water is estimated at $16 Billion per year and the industrial wastewater market is estimated to be in excess of $300 Billion annually. Exergy delivers technologies to make the concept of "closed-loop Factory" a reality. We can no longer waste resources and expect to continue to have access to the latest tech products.

Bot Watt is an online Data as a Service (DaaS) startup in the clean energy industry. Our mission is to be the go-to source for clean energy project data across the United States in the coming decade. The key areas where Bot Watt differentiates itself from the competition are data collection (method and type), price/business model, and integration of user-generated content. Our data collection method involves scraping data from other online sources, as well as public records requests. Our goal is to collect data and information for all types of renewable energy projects (wind, solar, geothermal) as well as all sizes of projects (residential solar, distributed generation, and utility-scale generation). Smaller project data is something notably absent from the marketplace currently, but can still provide a huge amount of value to users since it is a large part of the market. In addition to paid plans, Bot Watt also incorporates free accounts in order to leverage the most user-generated content possible. Companies who form accounts with Bot Watt will be able to add projects they’ve recently completed, tag themselves in projects where they’ve provided services, and keep their page updated with relevant information about their company. Bot Watt is both a place where anyone can go to get a basic understanding of projects and companies and a place where more in-depth users can get detailed project information and analysis.

Aerialytic uses AI to automate the residential solar design process. Each home requires a custom solar design in order to estimate the energy savings it could have by going solar. It takes approximately 10 minutes to create one solar design. With over 120 million homes in the US and Canada it would take over 2,200 years to create a design for each home. Our AI could do it in a day. We are addressing the rising customer acquisition cost for residential solar companies by streamlining their quoting process. We provide our technology to solar companies via API as well as in an end-to-end sales software solution.
