How Mark Singer Made His Fortune
Mark Singer’s fortune began with a simple idea—a high-strength, versatile adhesive that could bond almost anything. In the early 1990s, Singer was working as a furniture designer when he became frustrated by the limitations of traditional glues.
He realized there was a need for a strong adhesive that could bond a variety of materials and withstand the elements.
After discovering a unique polyurethane adhesive in Indonesia, Singer recognized its potential and secured the North American rights to it.
He took the formula and modified it to create what would become Gorilla Glue. The product’s unique formula allowed it to bond materials like wood, metal, stone, ceramic, and even glass, and it quickly became a hit.
Singer’s business acumen helped him turn Gorilla Glue into a successful brand. In 1994, he launched the product, and it gained popularity quickly. The company’s growth was fueled by strategic marketing, word-of-mouth advertising, and a growing demand for reliable adhesives.
Singer’s marketing strategy capitalized on the product’s strengths. It emphasized its power and versatility, and caught the attention of DIY enthusiasts and professionals alike.
The real breakthrough for Gorilla Glue came when Singer expanded the product range to include different types of adhesives, including super glue, epoxy, and adhesives for specialized applications.
The company continued to grow and build its reputation as a reliable brand. Singer’s success can be attributed to his ability to identify a market need and innovate a product that would meet that demand.
The Birth of Gorilla Glue – What Is It?
Gorilla Glue is a polyurethane-based adhesive that is known for its strong bonding capabilities on a wide variety of materials. It is often marketed as a “multi-purpose” glue because of its versatility.

This characteristic makes it highly effective for repairing damaged objects and creating durable bonds between different materials.
