Why Measuring Social Impact is More Urgent Than Ever?

Sophie Robin is the co-founder and impact director of Stone Soup, a B-Corp consulting firm specializing in social impact measurement and strategy, which she founded 18 years ago with two other partners.

Stone Soup was born from the conviction that the social economy sector needed the tools of the consulting world without giving up its values. At a time when the words "consulting" and "social" could hardly go together, its founders decided to create a hybrid structure: neither an NGO nor a conventional company, but a social enterprise with a parasocial agreement that limits dividend distribution and narrows the internal wage gap.

Today, Stone Soup supports organizations in building social programs, designing financial sustainability strategies, and strengthening their organizational capacity, but its DNA is impact measurement. That’s why Robin understands well the mistakes the sector continues to make, such as confusing activity with impact, or, even more commonly in recent years, the opposite problem: organizations measuring with such detail and rigor that they no longer know how to simply communicate what they do or the lessons they have learned.

“There is a tendency to measure my impact, what I do, but in reality, we are working in systems. Now this notion of collective impact is emerging, and we need to move towards that, not focus on our own navel because we are not working in silos. What we do affects other sectors,” argues Robin.
