Impact Metrics: Beyond Financial Returns
Good Growth Capital takes a comprehensive approach to measuring the success of their water technology investments, recognizing that true impact extends far beyond financial returns. The firm has developed a sophisticated impact measurement framework that evaluates environmental and social outcomes alongside traditional financial metrics.
Their environmental impact assessment focuses on quantifiable water-related metrics including gallons of water conserved, contaminants removed, and energy efficiency gains in water treatment processes. Each portfolio company tracks and reports these metrics quarterly, providing granular data on their contributions to water sustainability. This data-driven approach allows Good Growth Capital to demonstrate concrete environmental benefits to stakeholders while identifying opportunities for optimization.
On the social impact side, the firm evaluates how their investments improve water access, quality, and affordability for underserved communities. They measure metrics like the number of people gaining reliable water access, reduction in waterborne illness rates, and cost savings passed on to consumers. Portfolio companies must also demonstrate strong water equity practices, ensuring innovations benefit diverse populations rather than exacerbating existing disparities.
Crucially, Good Growth Capital has developed standardized methodologies for measuring both direct and indirect impact. Direct impacts are straightforward to quantify – for example, gallons of wastewater treated or contaminants removed. Indirect impacts like improved community health outcomes or ecosystem benefits require more sophisticated measurement approaches incorporating public health data and environmental indicators.
The firm has integrated impact metrics into their investment due diligence and ongoing portfolio management processes. Impact potential is evaluated alongside financial projections when screening potential investments. Portfolio companies receive hands-on support in developing impact measurement systems and are held accountable to impact targets just as they are to financial goals.
This dual focus on impact and returns aligns with growing evidence that environmental and social performance drives long-term financial success, especially in the water sector. As discussed in a recent analysis of impact investing in water, companies delivering measurable sustainability benefits often see stronger customer adoption, regulatory support, and operational efficiency.
