Warby Parker's Neil Blumenthal advises startups on scaling, from creating niche movements and vetting franchisees to mastering delegation.

Frame Employee Tenure as a 'Train Journey' Where People Get On and Off at Different Stops

To combat the stress of finding the 'perfect, permanent' employee, view the company as a long train journey. Employees get on and off at different points, which is natural. The focus should be on ensuring their time at the company is valuable and full of growth, not on achieving indefinite tenure.

In Job Interviews, Ask Candidates When They First Heard About Your Brand to Gauge Genuine Passion

Don't Try to Change Consumer Habits; Insert Your Product Into Their Existing World

Changing ingrained consumer behavior is incredibly difficult. A more effective strategy is to understand the customer's current world—how they shop and where they look for products—and insert your brand into those existing patterns rather than attempting to create entirely new behaviors from scratch.

Growth-Stage Startups Should Avoid Hiring From Large Corporations Who Expect Established Systems

New CPG Brands Should Target Pre-Existing 'Tribes' to Amplify Their Message Instead of Converting the Mainstream

For a niche product like non-fluoride toothpaste, the strategy is not to change everyone's habits at once. Instead, hyper-focus on a pre-existing community—a 'tribe' that already shares strong beliefs and will act as natural evangelists, amplifying the product's message organically within their network.

Outsource Commodity Functions Like Fulfillment to Focus Exclusively on Core Brand Competencies Like Design

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.
