Former Arsenal and Crystal Palace midfielder Mathieu Flamini has revealed that leaving the Gunners for Palace in 2016 was a painful decision, but the Frenchman is now a multi-billionaire thanks to his successful green chemistry venture.
Flamini, who played for both clubs during a stellar football career, now boasts a net worth of approximately £10 billion, a figure that dwarfs the estimated £780 million Arsenal spent assembling their Premier League-winning squad.
From Football to Green Chemistry
After retiring from professional football in 2018 following a brief stint with Getafe, Flamini focused all his efforts on GF Biochemicals, a company he co-founded in 2008. The firm specializes in producing sustainable alternatives to oil-based products, particularly levulinic acid, a molecule hailed as a holy grail for its ability to reduce the carbon footprint of household products by up to 80% compared to petroleum.
Flamini, who holds a 60% stake in the company and serves as its CEO, has seen his fortune skyrocket as GF Biochemicals became the first company to mass-produce levulinic acid.
Reflecting on His Arsenal Exit
Speaking about his move to Crystal Palace in 2016, Flamini admitted it was difficult to see his former club struggling. 'It is painful because I am still an Arsenal fan,' he said. 'I had some amazing times with Arsene Wenger. He did so much for myself. It is difficult for me to comment from the outside what is happening with Arsenal. Results are not what they want, that is for sure.'
Flamini initially joined Arsenal in 2004, the summer after their Invincibles season, and spent four years under Wenger before moving to AC Milan. He returned to the Gunners in 2013 and left for Palace on a free transfer three years later.
Parallels Between Football and Business
In an interview with Harvard Business Review, Flamini drew parallels between top-level sport and entrepreneurship. 'Football is a team sport but performance remains individual. As a player, you are judged on your own results. As a business leader, your role changes completely: you become a coach. The team comes first, and you are judged by your team's performance,' he said.
He added: 'We launched over 10 years ago, but our first product has only recently been brought to market. It is therefore a long-term investment that requires patience. Team spirit is also essential for overcoming difficulties. As a leader, you need to be a good listener while remaining clear about the vision and objectives.'
Flamini's success story serves as a remarkable example of how a professional athlete can transition into a thriving business career, with his green chemistry company now valued at billions.
