“You can’t really talk about impact measurement without the word management in there. For me, the two things go hand in hand and are synonymous, because there’s such an important relationship between them.”

Dean Hand

Chief Research Officer

“Things have changed pretty dramatically in the past 13 years. I don’t know any impact investor now who can go raise a fund without having a really thoughtful and detailed plan for how they’re going to measure and manage impact, to optimise for positive outcomes.”

Sarah Gelfand

Managing Director

“As I reflect over the 18 years that I’ve been in this industry, I feel that we’re now approaching an inflection point. Over the past 2 to 3 years we’ve begun to see increasing consolidation around both language and a common set of frameworks.”

Kylie Charlton

Managing Director

“Increasing fluency in the tools and standards developed as part of impact practice is central to building confidence and encouraging more people to make the shift from SDG alignment to advancing SDG and sustainability-oriented action.”
