Impact Measurement

Impact Measurement is the practice of quantifying and evaluating the social, environmental, and economic outcomes resulting from investments. In impact venture capital, measurement goes beyond simply tracking financial returns to assess whether portfolio companies are creating the intended positive changes articulated in the fund's impact thesis. The field has developed increasingly standardized approaches including the Impact Management Project's five dimensions (What, Who, How Much, Contribution, Risk), IRIS+ metrics from the Global Impact Investing Network (GIIN), the Operating Principles for Impact Management, and B Lab's B Impact Assessment. Impact measurement involves setting baselines, collecting ongoing data from portfolio companies, attributing outcomes to the investment (additionality), and reporting to stakeholders. The cost and complexity of measurement is a real challenge, particularly for early-stage companies with limited resources, leading to debate about proportionality and the risk of 'metric fatigue' overwhelming founders.
