“The Vistria Group has the vision, drive, and momentum to help grow businesses that have the potential to make an extraordinary impact on our world, at a time when we need it more than ever. The challenges our society faces are urgent and growing, and every one of those challenges presents an opportunity for investors and businesses to contribute to positive, measurable outcomes. I am joining Vistria because now is a pivotal moment for evolving how private investment works with businesses to maximize positive impact.,” Kelly McCarthy said. “Vistria has shown tremendous leadership in delivering measurable outcomes for stakeholders most affected by today’s challenges. I’m delighted to be given the opportunity to leverage the Firm’s scale, expertise, and track record to elevate its role as a model in the impact investing industry.”

She joins Vistria PRG, LLC (“Vistria PRG”), the in-house team of professionals at Vistria that supports management teams as they lead their companies to achieve top growth and performance potential.

Kelly most recently served as Chief Impact Officer at the Global Impact Investing Network (GIIN), an organization founded in 2008 to increase the scale and effectiveness of impact investing. In that role, she was instrumental in leading the organization’s work to develop tools and infrastructure for integrating impact into investment management. She was the chief architect behind the IRIS+ system, the widely used impact investing standard that helps investors incorporate social and environmental factors into investment decisions. She also oversaw the strategy and development of the industry’s first impact benchmarks.
