Our Story

If you listen, you learn. Our goal is to put listening back where it belongs, at the heart of social impact measurement.

To do this, we help social change organizations listen to the people that matter most - their customers, beneficiaries, suppliers or employees – through an approach to impact measurement and customer insights we call Lean DataSM.

Lean DataSM 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 also 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 was beginning to get cross-portfolio, comparable impact data that went beyond basic measures such as “lives impacted.” As important, Acumen’s investees found this impact measurement valuable in helping them understand and better serve their customers. As Acumen started to share these results, and the techniques used to get them, other organizations started asking if Lean Data could help them better understand their social impact.

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 within Acumen.

Today, we are relentlessly focused on providing high-speed, high-quality, end-to-end customer insights and impact measurement services, anywhere in the world.

We are also excited to be building some of the social sectors deepest benchmarks of social impact, allowing organizations to see how they’re doing compared to their peers.

If you’re interested in a better way to listen and understand your impact, we’d love to talk.
