60 Decibels is a tech-powered impact measurement company that makes it easy to listen to the people who matter most. We've been in business as an independent entity since early 2019, when we spun out of the global Impact Investor Acumen.

We collect social impact data directly from beneficiaries (customers / employees / suppliers) using our network of 1000+ trained research assistants in 75+ countries. We do it quickly and without the fuss typically associated with measuring social impact. Our research assistants speak directly to customers to understand their lived experience; and our team turns all this data into benchmarked social performance reports, with accompanying insights, to help our clients demonstrate and improve social performance.
By making impact measurement simple, scalable, and comparable, we not only enable organizations to improve their products and services; we also help transform what it means to credibly measure impact, ensuring that the voices of those who matter most are always part of the story.
