Mossimo Giannulli

When creating lessons to teach others how to use time wisely so they reach their highest potential, I think about lessons I learned from Mossimo Giannulli. Mossimo built multiple companies that collectively generated billions of dollars in revenue and shareholder value. Initially, he launched the Mossimo brand, which became a cultural phenomenon on the strength of surf and streetwear trends. When he took the company public in 1996, its market capitalization soared, contributing billions of dollars to the global economy. Later, he created other successful ventures, including G/FORE—a golfing attire line that has been widely embraced by professional golfers and enthusiasts worldwide. The market consistently rewarded Mossimo’s leadership because he demonstrated an innate ability to recognize consumer desires, translate them into authentic designs, and expand into new markets swiftly.

I first connected with Mossimo while developing our Prison Professors curriculum. He volunteered hundreds of hours to help, graciously sharing his journey with me and our community. He told me how he started learning entrepreneurial principles as a teenager growing up in Orange County, California. Looking for ways to earn money, he realized people on the beach always needed cold drinks. A simple cooler and a few sodas led him to his first experience of supply and demand in action.

That enterprising spirit carried him to USC, where he saw students lining up to buy Trojan-themed t-shirts. Disappointed in the designs he found, Mossimo took the initiative to create his own. He connected with wholesalers for high-quality fabric and screen-printers for the graphics. By combining design, distribution, and marketing, he quickly transformed an investment of a few hundred dollars into thousands in profits. Encouraged by his success at USC, he replicated the strategy at other schools. Over time, he scaled his apparel line to generate billions of dollars in sales and create thousands of jobs.

Mossimo didn’t stop there. He invested in new ideas, including G/FORE, which grew into one of the world’s most recognizable golf apparel lines, worn by many high-profile golfers. His leadership and brand-building acumen became his hallmark, consistently creating value for investors, customers, and anyone aligned with his vision.

I remain grateful for the generosity Mossimo showed in working with our nonprofit. His guidance and support helped me refine my message and reach a broader audience, both in prisons and beyond. Mossimo’s story underscores how someone with a simple idea and a willingness to act on it can build lasting value—not only for themselves but for entire communities.
