These are the founders reshaping industries and refusing to accept “that’s just how it works” as an answer.
Building a world-changing company has never been a matter of age. What the founders on this list share is something simpler: each one spotted a gap the rest of the world had walked past and decided to do something about it. From ocean-cleaning hardware to bespoke steering wheels to safety gear that actually fits, here are ten entrepreneurs making a real difference in 2026.
1. Kaitlin McCarthy and Hilary Gallin, Co-Founders of ARX
Women in construction have been wearing PPE designed for men for decades. Kaitlin McCarthy and Hilary Gallin decided that was a problem worth solving. Their company, ARX, designs personal protective equipment specifically for women in industries like construction, where safety gear has historically been built around a male body.
McCarthy holds a Civil Engineering degree from Northeastern University and an MBA from Harvard Business School. Gallin studied Biomedical Engineering at Yale, attended medical school at Washington University in St. Louis, and also holds an MBA from Harvard Business School. ARX develops its products directly with women in the field, making sure feedback from the job site shapes every design decision. That people-first approach, they say, is also how they run the company itself.
2. Leo Wu, Founder and Owner of Exclusive Steering
Leo Wu built Exclusive Steering on a simple belief: if you care about your car, your interior should reflect it. Based in Willow Grove, Pennsylvania, his company has spent over 11 years crafting bespoke custom steering wheels for virtually every make and model on the road. Every wheel begins with an OEM core for perfect fitment, then gets finished with premium materials sourced from Japan and Italy. Wu approaches each build as though it is going into his own vehicle. In a market where customization often means choosing from a dropdown menu, that level of care stands out.
3. Boyan Slat, Founder and CEO of The Ocean Cleanup
Boyan Slat was 16 when a scuba dive in Greece revealed more plastic bags than fish. That observation became a school project, then a viral 2012 TEDx talk that led him to leave his aerospace engineering studies and found The Ocean Cleanup in 2013. Now 31, he has developed large-scale ocean cleanup systems and river interceptors that stop waste before it reaches the sea. By December 2024, the organization had removed over 20 million kilograms of plastic worldwide.
4. Alexandr Wang, Founder of Scale AI
Alexandr Wang founded Scale AI at 19 after leaving MIT, building a company that powers the data behind artificial intelligence systems. His platform helps companies and governments train AI models more efficiently, making him one of the youngest self-made billionaires in the world. Now 29, Wang helped position Scale AI at the center of the AI boom, working with major tech firms and public sector clients to shape how intelligent systems are built and deployed. In 2025, he stepped down as CEO following Meta’s investment to lead its Superintelligence Labs, while remaining on Scale AI’s board.
5. Arhan Chhabra and Max Morganroth, Co-Founders of Rove
Arhan Chhabra, 21, and Max Morganroth, 23, recognized on the 2026 Forbes 30 Under 30 Transportation list, created Rove to give younger travelers access to rewards without relying on credit cards. Their platform partners with major airlines, making global travel more accessible to Gen Z.
6. Daria Balatsky, Co-Founder of Alga Biosciences
Daria Balatsky co-founded Alga Biosciences to make agriculture dramatically cleaner, starting with one of the most overlooked sources of greenhouse emissions: cattle. Her company has developed a simple, scalable algae-based feed supplement that cuts methane emissions from livestock by up to 97 percent.
7. Mikaila Ulmer, Founder and CEO of Me & the Bees Lemonade
Mikaila Ulmer started her company in Austin, Texas, at four years old after being stung by bees twice in one week. She built the brand around her great-grandmother’s recipe, sweetened with honey. Today, her brand is sold nationwide and donates a portion of profits to bee conservation efforts.
8. Riya Karumanchi, Founder of SmartCane
Riya Karumanchi reimagined the traditional white cane by integrating sensors, GPS navigation, and computer vision. Her invention helps visually impaired users detect obstacles and navigate their surroundings more safely and independently.
9. Will Smith, Founder of Bud Bar Displays
Starting as a Navy veteran with a background in plastics fabrication, Will Smith built a reputation designing high-end display cases for major retailers and Hollywood memorabilia. After a life-changing injury, he identified a gap in the cannabis retail space and created Bud Bar Displays, known for its patented pods and displays that combine security features with customer engagement through aroma delivery systems, magnifying lenses, and secure, tether-ready designs.
10. Jeanne Starmack, Founder of Cat-in-the-Bag
Jeanne Starmack founded Cat-in-the-Bag after creating the Cozy Comfort Carrier for her cat, Gremlin, who became sick in a traditional crate. After two years of development, she designed a secure, wearable carrier with a heads-out design that reduces stress and improves handling, helping pet owners manage travel, grooming, and everyday care with greater ease and comfort.
The Common Thread
So what connects these founders? It’s not age, funding, or even industry—it’s mindset.
Each of them saw something broken, overlooked, or outdated, and chose to fix it. Whether it’s safer gear, cleaner oceans, or smarter technology, their success comes from acting on ideas others ignored.
The takeaway? The next generation of world-changing companies isn’t coming—it’s already here. The only question is: who’s next?
