Lean DataSM, our approach to social impact measurement, was created in 2014 by Acumen, a not for profit patient capital investor. Acumen sought to build a way to measure impact that both met its needs as an investor and created significant value for its investees.
After lots of experimentation, much of it focused on finding the best ways to measure impact using mobile phones, by 2015, Acumen had cross-portfolio, comparable impact data that went beyond basic measures such as “lives impacted.” As important, Acumen’s investees found that Lean DataSM helped them understand and better serve their customers.
In early 2019, recognizing the potential to make a positive contribution to the wider sector by scaling this new approach to measuring impact, Acumen spun out Lean DataSM to create a new company, 60 Decibels, founded by the team that built Lean DataSM at Acumen.
