Marlyn Schiff’s first strategic hires were for sales, specifically to get into trade shows and secure orders. The founding team handled fulfillment until sales volume demanded dedicated roles. This "sales-first" approach ensures there is a business to support before investing in operational overhead.

Many 3PLs use cheaper, modern shipping carriers while still billing you at legacy rates for companies like FedEx or UPS. Regularly auditing your 3PL invoices for this arbitrage can uncover a "gold mine" of savings to add directly to your bottom line.

Contrary to common belief for online-native brands, Peak Design's own retail stores have the highest contribution margin. This is because shipping products in bulk freight to stores is cheaper than covering the high last-mile delivery costs for individual e-commerce orders, which often qualify for free shipping.

To combat razor-thin margins, Diapers.com's key innovation was deep logistics optimization. They hired a PhD in nuclear physics to develop an algorithm that calculated the perfect box size for every order, minimizing dimensional weight shipping charges and making their loss-leader model viable.

Despite a profitable affiliate model, Babylist was heavily reliant on a few large retailers. They chose to enter the complex, lower-margin world of direct e-commerce and warehousing primarily to mitigate platform risk and control their own destiny, not for short-term profit.

Shipt identified markups, fees, and tips as a key driver of churn. Since tips and some fees were unavoidable, they strategically focused on eliminating markups—the one component of the cost structure they could directly control—to create a powerful competitive advantage.

Founders must distinguish between core competencies unique to their brand (e.g., product design) and commodity tasks (e.g., warehousing). Commodity functions should be outsourced to experts who benefit from economies of scale, freeing up internal resources to focus on what creates true differentiation.
