The Challenge: Finding a 3PL Built for the Next $100M Brand
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:
- Show a proven track record with fast-growing CPG brands
- Deliver real SLA performance, not just promises—especially around order accuracy, inventory, and responsiveness
- Support true omni-channel execution, from DTC and retail to Amazon and TikTok Shop
- Offer tailored tech integrations, high-touch fulfillment, and responsive account management
- Handle complex compliance requirements, from EDI to FEFO inventory and temperature-sensitive routing
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.

Rapid Omni-Channel Expansion: From DTC to Amazon, TikTok, and Retail in 6 Months
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.
In just 6 months, David accomplished what most brands take 24 months to achieve.
- Fulfilled 10,000 pre-sale orders in a single day
- Scaled to over 30,000 monthly DTC orders (with strong traction on TikTok)
- Successfully launched on Amazon during Q4 peak season, while maintaining order accuracy and meeting increased demand
- Introduced new flavors and SKUs during the same Q4 peak, with Atomix seamlessly supporting the expansion without missing a beat
Scaling Into Retail With Unmatched Compliance Support
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.
The Science of Inventory Control & Freshness: Lot Control
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.
Rules-Driven Cost Efficiency & Customization
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:
✅ Optimized packaging selection
Ensuring each order was shipped in the most cost-effective box, minimizing DIM weight charges and saving David tens of thousands of dollars.
✅ Smart Carrier Routing
Selecting the ideal shipping method based on destination, order volume, and environmental conditions, ensuring on-time delivery with optimal cost savings.
✅ Custom packaging tracking
Atomix monitored custom packaging levels, providing David real-time insights on when to reorder branded boxes, ensuring uninterrupted brand consistency in every unboxing experience.
Superior Support from Atomix as David’s Last Quality Checkpoint
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.
