When Peter Rahal, the founder of RXBAR, and Zach Ranen of RAIZE launched David Protein in September 2024, they weren’t just starting another protein bar company—they were redefining the industry. With $10 million in seed funding and a product built for premium nutrition, gamified purchasing experiences, and community-driven growth, they needed a logistics partner who could keep up with their relentless focus on quality and scale.
From a zero-order start in August to nearly 30,000 orders fulfilled in September and over 200,000 orders shipped in just six months, Atomix Logistics has been the backbone of David Protein’s expansion. But beyond the numbers, this partnership was about precision, compliance, and a shared commitment to innovation.

Peter Rahal (founder of RXBAR) and Zach Ranen (of RAIZE) had worked with nearly every type of 3PL—from retail-focused warehouses to massive enterprise providers. But with David Protein, they needed something fundamentally different: a logistics partner that could scale with them from zero orders to $100M in revenue without skipping a beat.
They approached several 3PLs, searching for one that could:
David’s team was looking for more than a warehouse—they needed a partner with operational expertise, flexible support for one-off projects, and the infrastructure to scale with them every step of the way.
“The Atomix team has been a valuable partner in our growth. They operate as an extension of our team with quick response times and a problem-solving mindset. Even as order volumes scale, we can trust that the Atomix team will execute to high standards. I recommend them for great service to other e-commerce operators.”
Atomix delivered on every need—and exceeded expectations—through a fulfillment operation engineered for scale, flexibility, and precision:
Launching a high-growth CPG brand is chaotic. Logistics bottlenecks, compliance hurdles, and inventory tracking mishaps can derail momentum before it even starts. Atomix ensured a flawless launch, operating as David’s logistics nerve center, catching critical details that could have disrupted fulfillment, from shipping international orders, adjusting for customs changes in Canada, and even responding to postal service strikes that hit the week after launch.
With Atomix’s historical performance of 99.7% order accuracy, 98.8% on-time fulfillment, and 99% inventory accuracy, David’s operations team could rest easy. The brand could focus on growth, knowing that Atomix was handling the intricate details of order fulfillment, compliance, and delivery speed to ensure customer retention, satisfaction, and long-term scalability.

David’s retail expansion wasn’t just fast—it was meticulously executed. Within three months, Atomix facilitated the brand’s entry into 20+ regional stores and 10+ national chains, including The Vitamin Shoppe and Westside Market.
Retail compliance is a make-or-break game. A single misstep—incorrect EDI setup, improper packaging, or mismanaged purchase orders—can result in chargebacks, refused shipments, and lost retail opportunities. Atomix not only set up EDI connections to seamlessly integrate David into major retail systems but also consulted on each retailer’s specific fulfillment requirements to prevent errors, saving David thousands in potential compliance penalties.
The result? A near-100% retail fulfillment accuracy rate, making David a preferred vendor among its retail partners.
David Protein isn’t just obsessed with flavor—it’s obsessed with product integrity. Protein bars degrade under poor storage conditions, and customers expect fresh, pristine products with every order. Atomix utilized its temperature-controlled storage and delivery system to protect product quality at every stage.
Using First-Expired, First-Out (FEFO) inventory management, Atomix ensured that every bar shipped at peak freshness. In hotter months, the Atomix shipping rules engine rerouted orders to destinations over 70°F onto 2-day air delivery, ensuring customers always received a perfectly preserved product. This strategic fulfillment model directly increased customer retention and repeat purchases, driving long-term revenue growth.
Scaling an e-commerce and retail operation isn’t just about moving more units—it’s about doing it smarter. Atomix’s Rules Engine powered key efficiencies, including:
David Protein’s commitment to premium quality extends beyond the product itself—the unboxing experience matters just as much. Atomix took this seriously, implementing a custom packout procedure developed in collaboration with the David team.
Every bar, box, and shipment was carefully reviewed, making Atomix the last line of defense for product integrity before it reached customers. The Atomix operations team ensured that every order was fulfilled flawlessly, maintaining strict QC standards to enhance the customer experience.
✅ Dedicated “pod manager” overseeing every detail of David’s fulfillment.
✅ 24-hour SLA for DTC orders to maintain freshness and speed.
✅ First Response Time - Chat: 10 minutes for immediate fulfillment support.
✅ Urgent Issues: Under 2 hours, Simple Issue Resolution: 4 hours.
The partnership between David Protein and Atomix Logistics wasn’t just about fulfilling orders—it was about scaling a brand with shared values of quality, innovation, and efficiency.
Instead of endless email chains and delayed responses, Atomix onboarded David Protein directly via Slack, creating seamless, real-time communication between David’s team and Atomix’s operations experts.
With a logistics foundation built for scale, David Protein could focus on product innovation, brand growth, and expanding its retail footprint, knowing Atomix had the logistics covered.
✅ Zero-to-30,000 orders in 30 days, 200,000+ in 6 months.
✅ Seamless expansion into 20+ regional stores, 10+ national chains.
✅ Near-100% retail fulfillment accuracy, eliminating chargebacks & refused shipments.
✅ Tens of thousands of dollars saved through smart shipping & packaging optimizations.
✅ Strict FEFO lot control + temperature management = highest product integrity & freshness.
✅ 24-hour SLA, 99.7% order accuracy, and a QC-first fulfillment process.
David Protein is just getting started. With a rapidly expanding product line and an aggressive retail strategy for 2025, the brand is on track to become a household name in high-protein nutrition.
Atomix will continue to provide the infrastructure, agility, and expertise needed to support this growth. With retail partnerships multiplying, customer retention skyrocketing, and operational efficiency driving profitability, the David-Atomix partnership is a blueprint for CPG success.
"A shared vision of quality and scalability between Atomix and David resulted in fewer emails, streamlined communication, and unmatched execution."
