Mark Singer isn’t just a name tied to Gorilla Glue — he’s the force who turned a simple adhesive into a household name. As of 2025, Mark Singer’s estimated net worth stands around $300 million, largely driven by the massive success of Gorilla Glue Company. But how did he build such an empire, and what makes his journey so unique? Let’s break it down.
From Acting to Entrepreneurship
Born November 12, 1955, in Cincinnati, Ohio, Singer is now 69 years old. Interestingly, he didn’t always have his sights set on business. In fact, he initially pursued acting. He studied drama at the University of Washington School of Drama and found early success throughout the 1970s, appearing in multiple films and television projects.
But even as his acting career flourished, Singer felt a pull toward something different. That change came in the 1990s when he made a bold career shift into entrepreneurship. That pivot laid the groundwork for what would become one of the most trusted adhesive brands in the world.
The Birth of Gorilla Glue
The idea behind Gorilla Glue came from a polyurethane adhesive originally used in Indonesia for bonding teak wood. Singer saw the product’s potential and knew it could disrupt the glue market in the U.S.
In 1994, he founded Gorilla Glue Company. What started as a single product meant for industrial use quickly grew into something bigger. The glue worked on nearly everything — wood, stone, metal, glass, and more — and that versatility made it wildly popular with both contractors and everyday consumers.
Marketing That Stuck
One of Singer’s biggest strengths has been his marketing strategy. Instead of going the dry, technical route, the brand leaned into humor and memorability. The use of an actual gorilla mascot in commercials made the product stand out. That visual identity helped consumers remember and trust the product.
And it didn’t stop there. The brand embraced the power of digital marketing early. By investing in SEO, influencer partnerships, and viral content, Gorilla Glue stayed relevant across generations. A major viral event — the Tessica Brown incident (aka “Gorilla Glue Girl”) — unintentionally boosted brand visibility worldwide. While it was a PR nightmare on one hand, it showed how sticky (pun intended) the brand was in people’s minds.
A Growing Empire
Mark Singer didn’t just stop at one product. Under his leadership, Gorilla Glue introduced a wide range of new offerings — Gorilla Tape, Gorilla Super Glue, Gorilla Epoxy, and more.
Each product launch was successful, keeping the company ahead of competitors. By sticking to quality, reliability, and creative branding, Gorilla Glue became a go-to product for DIYers, carpenters, and families alike.
Today, the company is valued in the billions, and Singer’s personal stake in it has contributed massively to his $300 million net worth. His ownership of the company’s stocks, combined with smart reinvestment strategies, has kept his financial growth steady.
Diverse Investments & Philanthropy
Singer didn’t put all his eggs in one basket. Apart from Gorilla Glue, he has invested in real estate and technology startups, further boosting his wealth.
He’s also big on giving back. Through The Gorilla Glue Foundation, Singer supports STEM education for underserved communities and funds environmental sustainability projects. The foundation works to inspire young minds to engage with science and innovation, much like Singer did in his own journey.
Personal Life & Values
Mark Singer is a family-oriented man. Though he keeps much of his private life away from the media, it’s known that his family has always been supportive of his ventures. His wife and children, though not public figures, have been a part of his business legacy.
He also remains rooted in Cincinnati, the city where it all began. Singer believes in staying close to his roots, often involving local talent in marketing and manufacturing operations.
