From Garage to $100M: XXL Nutrition's Growth Story

Dr. Niklas Richter · 2026-05-21

René van der Zel didn't set out to build a giant. He just wanted to solve a problem. What started in his garage without a master plan became XXL Nutrition, a company that now pulls in over $100 million in revenue and employs more than 200 people. No investors. No slick five-year plan. No corporate playbook. Just a guy who listened to customers and got better every day. ### Growth Was Never the Goal Here's the twist: XXL Nutrition never chased growth. It wasn't the target. It wasn't the strategy. Growth just happened because they focused on being better. René says it plainly: nobody wants a product. People want a solution to their problem. Once you get that, you don't need fancy marketing tricks. You just need to deliver. Be easy to reach. Take your customers seriously. Forget your ego and focus on their needs.  ### Why They Skipped Market Research Most companies spend thousands on market research. XXL Nutrition didn't. Why? Because René and his team were their own customers. They understood the pain points because they lived them. That insider perspective shaped everything: product development, customer service, even how they handled complaints. It's a reminder that sometimes the best research is just paying attention to your own experience.  ### Customer Service Is Not a Cost A lot of businesses treat customer support like an expense to minimize. XXL Nutrition sees it differently. For them, customer service is the foundation. It's where trust gets built. It's where problems get solved before they become big deals. René believes that if you treat customers like real people, they'll do your marketing for you. Word of mouth became their biggest growth engine—and it didn't cost a dime. ### Small Improvements Add Up This isn't a story about one big breakthrough. It's about hundreds of small wins. A better label on a bottle. A faster response to an email. A product that actually works. René calls it "normal being normal." No grandstanding. No hype. Just consistent, everyday effort. Over time, those tiny upgrades compound into something massive. ### What Entrepreneurs Can Learn - **Start with the problem, not the product.** If you understand what people truly need, the product almost sells itself. - **Let customers guide you.** They'll tell you what's broken and what works—if you're willing to listen. - **Keep it simple.** You don't need complex systems or expensive consultants. Good service, clear communication, and genuine care go a long way. - **Don't chase growth.** Focus on being excellent, and growth will follow. ### The Bigger Picture René's story is a refreshing counterpoint to the hustle culture that dominates business media. He didn't raise millions. He didn't hire a PR firm. He just kept showing up, kept improving, and kept his customers at the center of every decision. That's it. No magic formula. No secret sauce. Just a lot of small, smart moves made over time. This episode is a masterclass in building something real. It's proof that you don't need a boardroom or a venture capital fund to create a successful company. You just need a problem worth solving, a willingness to listen, and the patience to get better every single day.
