A Founder's Second Act: From RXBar's Simplicity to David's Innovation
After selling RXBar to Kellogg's for a reported $600 million in 2017, co-founder Peter Rahal spent his non-compete period planning his next act. His observation was that the protein bar market, while seemingly crowded, still left many consumers unsatisfied. He believed people wanted a bar that mimicked the high protein-to-calorie ratio of a protein shake, a concept that few, if any, companies had mastered in a solid-food format.
Rahal partnered with Zach Ranen, a veteran of the low-carb bakery brand RAIZE, and together they embarked on a year-long quest to engineer what he called the 'final protein bar'. The vision was simple yet technically complex: maximize protein while minimizing everything else. Unlike RXBar, which focused on a handful of clean, whole-food ingredients, David would lean on food science and cutting-edge components to achieve its ambitious nutritional targets. The expiration of Rahal's non-compete clause in October 2022 marked the beginning of a new era, culminating in the launch of David in the fall of 2024.
The Product and its Game-Changing Ingredients
The core innovation of the David bar lies in its high 'Calories From Protein' (CFP) ratio. David aimed for an unprecedented 75% CFP, far exceeding the 40-50% found in many competitor products. To accomplish this, they incorporated a unique ingredient: E.P.G., or esterified propoxylated glycerol.
E.P.G. Explained
- Low-Calorie Fat: E.P.G. is a modified plant fat that passes through the digestive system mostly undigested.
- Massive Calorie Reduction: This process delivers 92% fewer calories than traditional fats, allowing David to drastically cut total calories while maintaining desirable texture.
- Strategic Acquisition: In a controversial move to control supply, David announced in May 2025 that it would acquire Epogee, the sole manufacturer of E.P.G., a decision that led to antitrust lawsuits from other food companies who used the ingredient.
To bind the bar, David uses a blend of sweeteners and binders that also contribute to its low-calorie profile, including Maltitol and Allulose, which add sweetness without causing significant blood sugar spikes.
Branding: From Michelangelo's Sculpture to TikTok Virality
The marketing of David was as innovative as its ingredients. The brand name, inspired by Michelangelo's sculpture, evokes ideals of discipline, intelligence, and the perfected human form. The minimalist gold packaging and premium aesthetic set it apart from the more flavor-focused branding of its competitors.
David's go-to-market strategy was meticulously engineered for modern digital engagement:
- The Waitlist Launch: Before a single bar was sold, David built an email waitlist, creating scarcity and anticipation with exclusive access and giveaways.
- Micro-influencer Seeding: Instead of relying on a few costly celebrity endorsements, David sent products to hundreds of micro-influencers across fitness and wellness niches, generating authentic, user-generated content and viral buzz.
- TikTok Shop Domination: The brand aggressively leveraged TikTok Shop, featuring frequent QVC-style live-selling events with an army of affiliates. This approach fueled a viral sensation and drove explosive sales.
- High-Profile Backers: Investors and advocates include prominent health figures like physician Peter Attia and neuroscientist Andrew Huberman, which lend scientific credibility to the brand's premium image.
The Rapid Rise and Competitive Landscape
The combination of a truly differentiated product and a masterful marketing campaign led to explosive growth for David Protein. The launch was an immediate success, and the company quickly expanded its retail footprint to major chains.
David vs. The Competition: A Comparison Table
| Feature | David Protein Bar | Traditional Protein Bars (e.g., RXBar) | Quest Bars |
|---|---|---|---|
| Protein Content | 28g per bar | Varies, often 12-20g | Varies, often 20-21g |
| Calorie Count | 150 calories | Varies, often higher (200+) | Varies, often 180-210+ |
| Sugar | 0g added sugar | Generally low, but can contain natural sugars from dates/fruit | Generally low, uses artificial sweeteners/sugar alcohols |
| Key Ingredient | E.P.G. (fat replacer) | Whole foods like dates, egg whites, nuts | Isomalto-oligosaccharides (fiber) |
| Binding System | Maltitol, Allulose, Glycerin | Natural ingredients | Soluble Corn Fiber |
| Product Focus | Maximum protein efficiency | Transparency and minimal ingredients | High protein, flavor variety |
| Branding | Aspirational, premium, science-backed | Simple, straightforward, no BS | Traditional supplement aesthetic |
Future Outlook and Market Impact
David's success story is a testament to identifying a market gap and leveraging innovation and modern marketing to fill it. By prioritizing a high protein-to-calorie ratio, the brand catered to the 'protein maxing' trend and a growing demographic of consumers on GLP-1 drugs who are advised to increase protein intake. The acquisition of Epogee demonstrates a bold strategy to control supply and protect their key product differentiator. As the company looks to expand its product line, such as with the announced 'Bronze Bar' for a more mass-market appeal, its trajectory continues to reshape the protein bar industry. The story behind David Protein bars is not just about a new product, but about a founder's relentless pursuit of perfection and a calculated disruption of an established market.

Conclusion: The Final Bar Has Just Arrived
Peter Rahal's return to the protein bar industry with David was a strategic masterstroke, building on past experience while embracing new technologies. The brand’s story is defined by a rigorous focus on nutritional metrics, controversial but innovative ingredient use (E.P.G.), and a powerful, multi-channel marketing campaign. By positioning itself as a premium, science-backed product rather than just a tasty snack, David successfully differentiated itself and captured a significant market share almost immediately. The result is not just a high-protein bar, but a meticulously engineered tool for human optimization that represents the next evolution of the health food industry.
