More than 200 student innovators participated in Cox's sustainability hackathon, developing real-world solutions for energy, agriculture, transportation, circular economy and sustainable cities

Cox Enterprises has revealed the winners of its Play with Purpose Sustainability Hackathon, a five-day innovation challenge designed to help students transform ambitious sustainability concepts into actionable solutions.

More than 200 students from universities across Georgia, the Southeast and beyond developed ideas focused on energy, agriculture, transportation, circular economy and sustainable cities.

"The Play with Purpose Hackathon gave students the opportunity to apply their creativity and technical skills to some of the most important challenges facing our communities," said Jack Semrau, Atlanta Venture Ecosystem Lead at Cox Enterprises. "By bringing together students, entrepreneurs and industry leaders, we're supporting the next generation of innovators while strengthening Atlanta's position as a hub for sustainability and cleantech."

Hosted at the Historic Biltmore, once home to WSB Radio and a symbol of Atlanta innovation, the event was part of Cox's Play with Purpose programming and held in partnership with Atlanta Tech Week and the Georgia Cleantech Innovation Hub. The competition connected students with entrepreneurs and industry leaders as they developed practical solutions for real-world sustainability challenges.

The overall prize went to Stuti Thummala, whose project MaterialOps uses AI to help divert event waste generated by large-scale events from landfills by improving sorting and materials management. She received four tickets to the FIFA World Cup 2026 and a first-round interview for the Cox Cleantech Residency, an Atlanta-based initiative designed to help early-stage founders accelerate the commercialization of climate and sustainability solutions.

Thummala, a mathematics and computer science student at the Georgia Institute of Technology, found the experience particularly meaningful thanks to the support of her mentors.

"One of the things that drew me to this hackathon was the chance to build something with real-world impact," said Thummala. "It's exciting to see how technology can be used to create more sustainable outcomes at scale."

Why student innovation matters
The Play with Purpose Sustainability Hackathon reflects Cox Enterprises' commitment to investing in the next generation of sustainability leaders while helping address some of the world's most pressing environmental and infrastructure challenges.

"Hackathons matter when they connect young builders to real world problems that can be solved with cutting edge technology," said Avoilan Bingham, President of Atlanta Tech Week. "The Play with Purpose Hackathon was a fantastic opportunity to showcase the next generation of student builders building in Atlanta, and Atlanta Tech Week (August 9-14) was proud to stand alongside Cox and the Georgia Cleantech Innovation Hub to bring this to life."

Since 2007, Cox Enterprises has invested more than $3 billion in cleantech through a combination of operating businesses, venture investments and strategic partnerships. The company's cleantech portfolio includes businesses and initiatives such as Cox Farms, Nexus Circular and the Cox Cleantech Accelerator.

By connecting students directly with industry leaders and real-world business challenges, the hackathon helped build the talent pipeline needed to advance innovation across energy, agriculture, transportation, circular economy and sustainable cities.
