Who is Peter Rahal? Founder of RXBar and David Protein Bar
The Early Days: Building RXBAR Peter Rahal is a visionary entrepreneur best known for co-founding RXBAR, one of the most successful protein bar brands in recent years. The story of RXBAR began in 2013 when Rahal and his co-founder, Jared Smith, started making protein bars in Rahal’s parents' kitchen in Chicago. Their goal was to create a clean-label protein bar—one made with simple, whole ingredients that consumers could trust. The result was RXBAR, a minimalist brand that proudly listed its key ingredients (like egg whites, nuts, and dates) on the front of the packaging. Instead of raising outside capital, Rahal and Smith grew the business through direct-to-consumer sales and grassroots marketing. They targeted CrossFit gyms, fitness enthusiasts, and health-conscious consumers, leveraging social media and word-of-mouth to build momentum. The $600 Million Exit RXBAR’s growth was nothing short of explosive. By 2017, the company had reached $130 million in annual revenue, drawing interest from major food corporations. That same year, Kellogg’s acquired RXBAR for $600 million, allowing Rahal to cash out while continuing to work on the brand post-acquisition. However, as with many entrepreneurs who sell their startups to large corporations, Rahal eventually stepped away from the brand to pursue new ventures. David Protein: The Next Generation of Protein Bars After RXBAR, Rahal didn’t stop innovating. He co-founded David Protein, a high-protein, low-calorie bar brand designed for the modern consumer. David Protein is marketed as a protein bar for people using GLP-1 weight-loss medications like Ozempic and Wegovy. These medications reduce appetite, so the bars are positioned as a way to help users maintain muscle mass while consuming fewer calories. What Makes David Bars Different? - 28g of protein per bar - Only 150 calories - Zero sugar (sweetened with stevia and monk fruit) - Protein from whey isolate, collagen, and egg whites David Bars have gained attention for their lean macros, making them a favorite among fitness-conscious consumers and those looking for high-protein, low-calorie snacks.
