Focus Area

Wastewater Treatment

Dairy farms are not generally known for their sustainability, but that could change with the help of Gross-Wen Technologies. With the 2021 Accelerator Top Deployment Award, GWT will deploy a pilot project at one of the nation’s largest dairy operations to sustainably and cost-effectively recover nutrients from the wastewater—and reduce the farm’s carbon footprint. At scale, the project will produce 270 tons of dried algae, avoid 5,000 metric tons of CO2, and increase farm revenue by ~$1M every year.

Over the course of their time in the Accelerator program, GWT presented their technology to key IH2O partners such as Xylem, SUEZ, and Kurita; they also engaged with 19+ mentors in our network. In addition, when the GWT team was looking for an independent board member, we introduced them to five industry experts to consider for the role. After an extensive process, GWT selected one of our referrals and is actively discussing potential collaborations with the others.

Throughout the year, GWT gained transformational insights and connections as they expanded their customer pipeline, explored project finance, planned for strategic partnerships, and identified new market opportunities.

The Imagine H2O network and programming have been incredibly valuable to GWT as we continue to grow and refine our business model. Although we have learned several industry-specific lessons the hard way over the past several years, we would be a full year further along if we had gone through this program when we launched in 2017.

Case Study

Christine Boyle leveraged Imagine H2O to take her startup from idea to exit

Cohort

Imagine H2O Accelerator 2015

Focus Area

Digital Water

Valor Water’s leadership recognized that utilities were struggling to meet conservation goals while maintaining their financial viability. In response, the company created a proactive, data-driven approach to lowering apparent water loss, reducing unnecessary meter replacement, and optimizing revenue.

Imagine H2O played a critical role in honing Valor Water’s business model and go-to-market strategy. In fact, CEO Christine Boyle met her first two investors within minutes of Water Innovation Week in 2015! These investors became her earliest and most enduring supporters; one of them later joined the Valor Water board. Another Imagine H2O judge joined the team as an advisor. At the time, the company was still a few months away from a product launch; Imagine H2O’s recognition served as a powerful third-party validation, helping Valor Water secure critical investment.
