Gigi
Gigi Alsaadi is redefining how we think about sustainability. From leading climate impact tools at Prime Coalition to co-founding KanataQ, a marketplace connecting nearly 400 sustainability startups, her work makes environmental action practical and scalable. For Gigi, it all comes back to empathy: “I thought I’d help people through healthcare, but I found my path in helping the planet, and in turn, people.” Her advice to aspiring changemakers is simple yet powerful: layer sustainability onto your skills, stay curious, and keep moving forward, small steps can ripple into real impact.
Stella
Stella Nakawuki Lukwago, Country Manager for Youth Challenge International Uganda, grew up in Bwaise, one of Kampala’s toughest slums. Witnessing hardship early on, she promised to create change. After gaining experience abroad, she returned to empower rural youth and women through sustainable solutions like biodegradable straws. Stella’s leadership is about shifting mindsets and inspiring action—showing that real change starts with believing and taking the first step.

“John Liu: Capturing the Spirit of Running Through Photography” explores how street photographer-turned-sports storyteller John Liu found purpose behind the lens by documenting runners in motion. From casual joggers to elite athletes, Liu’s work celebrates perseverance, community, and the beauty of human effort—capturing not just the sport, but the spirit behind every stride.
Ignacio
Ignacio Tartavull grew up in Argentina with an insatiable curiosity for how things worked, so much so that new appliances rarely survived more than a few hours before he took them apart with a screwdriver. That curiosity led him from manufacturing engineering to brain research at Princeton and MIT, then into self-driving car development at Uber.
A tragic accident in 2018 shifted his path forever. “That crash showed me how much responsibility technologists carry. It’s not just about pushing innovation, it’s about lives and trust,” he says.
Determined to make safety the priority, Ignacio founded PinkBot, small, friendly, baby-pink delivery robots designed to replace errand driving, which accounts for 40% of trips and hundreds of thousands of deaths each year. Today, PinkBot delivers about 1,000 meals daily across U.S. cities, saving time, cutting emissions, and, statistically, saving lives.
For Ignacio, it’s not just about building robots. It’s about building trust, protecting communities, and proving that technology can be as caring as it is clever.
