New cleantech leaders will help scale Cox’s sustainability businesses and pursue new investments, building on more than $3 billion invested to date
ATLANTA, Nov. 10, 2026 /PRNewswire/ — Cox Enterprises today announced that Bill Nussey has joined the company as senior vice president of Cleantech and Matt Perkins has joined as vice president of Cleantech. Together, they will lead Cox’s cleantech efforts, helping scale existing companies, guide investment strategy and identify new opportunities.
Cox has invested more than $3 billion in cleantech companies and solutions, spanning plastics recycling, greenhouse agriculture and early-stage climate innovation. As a private, family-owned company with a multi-generational view, Cox invests patiently in businesses built to last. Nussey and Perkins will carry that work forward, supporting portfolio companies as they grow while continuing to evaluate new investment opportunities across the cleantech landscape.
“Scaling is what Bill and Matt do,” said Shereta Williams, executive vice president of Growth Operations at Cox Enterprises. “Both have successfully built and sold companies, and Bill has been an investor and champion in the industry for more than a decade. Together, they bring valuable experience to grow our existing portfolio and to find what’s next.”
As senior vice president, Nussey will help scale Cox’s cleantech businesses, shape its investment approach and lead the search for new growth opportunities, working alongside portfolio company leaders. A four-time CEO, he built the software company Silverpop to almost 1,000 employees before its sale to IBM and led iXL through its initial public offering to a $3 billion market valuation. Over his career, Bill has acquired and integrated dozens of companies. He has focused on clean energy since 2017, most recently as a partner at Tech Square Ventures, where he led cleantech investments and ran Engage, an enterprise accelerator and venture fund backed by 15 major Southeast corporations, including Cox. Nussey is the author of Freeing Energy, a 2022 U.S. Department of Energy Clean Energy Champion and a TED speaker on the future of energy.
“This is cleantech’s moment,” said Nussey. “The opportunity has grown beyond inventing new technologies to something that can change the world: building the companies that deliver those technologies at scale, profitably. I’ve spent my career turning promising technology into scalable, high-growth businesses, and nothing I’ve worked on compares to the potential of cleantech. Cox brings a rare combination of patient capital, operating excellence and a multi-generational commitment to a better future. I’m thrilled to join Cox and to help show the world that cleantech is not just great for the planet, but also great for business.”
As vice president, Perkins will work closely with portfolio companies on growth and operations and help source and evaluate new investments.
Perkins joins from Alaska Renewables, which he co-founded and led as CEO, building from scratch a developer of large-scale wind, solar, battery and geothermal projects and selling its first project portfolio to Longroad Energy. He previously served as chief product officer at Rondo Energy, an industrial heat storage company, and chief marketing officer at 7AC Technologies, an HVAC startup acquired by Emerson in 2020. He has focused on cleantech since 2006, starting his career at GE where he helped launch the company’s solar product lines, served various assignments based in China, and co-founded the energy optimization business that became Current.
“The cleantech companies that win focus relentlessly on market problems that innovative technology can solve, and then prove those solutions with customers,” said Perkins. “Cox has the businesses and the long-term mindset to do that at scale, and I look forward to strengthening and growing its cleantech portfolio.”
Cox is always looking for what’s next in cleantech. The company will continue to engage with founders, investors and partners on new opportunities that fit its long-term approach to building businesses.
