For new physical product companies, the best manufacturers are often too busy and risk-averse to work with newcomers. Conversely, factories that are overly eager for an unknown startup's business may have underlying quality or reliability issues.

For D2C fashion brands, the inability of third-party suppliers to quickly fulfill reorders on trending products is a key trigger for vertical integration. Larroudé's co-founder realized the cost of one large factory order was equivalent to buying the machinery himself, enabling them to meet demand in weeks, not months.

Founders of artisanal businesses should deconstruct their workflow into key stages (e.g., design, component production, assembly, fulfillment). The founder should retain control over creative, brand-defining steps while systematizing or outsourcing the consistent, repeatable tasks. This allows for scaling without sacrificing brand integrity.

A founder's instinct is to delegate tasks they are bad at, such as finance, to get them off their plate. However, this creates dangerous blind spots. To be a responsible leader, you must force yourself to engage with and understand every part of the business.

To ensure a smooth transition from development to production, an operations or manufacturing SME must be part of the design process from the start. Otherwise, products are developed without manufacturability in mind, leading to expensive, reactive fixes and subjective quality control during scale-up.

For hard tech startups, the decision to vertically integrate and build a factory shouldn't be automatic. It's a strategic imperative only when "cadence"—the speed of iteration and delivery—is the primary competitive advantage. In such cases, the in-house capability to move fast outweighs the high capital cost.

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.

Companies, especially in early stages, should resist outsourcing production too quickly. Keeping a new process in-house is essential for understanding its pain points, which is a prerequisite for being able to specify clear, effective requirements to an external vendor later on.

A-Frame's CEO warns that retailers can 'love you to death.' Accepting a full-chain launch is tempting, but the marketing and inventory costs can be overwhelming for a young brand. He advises founders to negotiate a smaller, focused launch to prove the concept before expanding.
