LEGO's CEO notes that absorbing new hires into the culture at its established HQ is easy due to the high density of tenured "culture carriers." The real challenge is scaling culture in new, specialized hubs, which requires a much more deliberate effort because that organic cultural osmosis is absent.

As a company grows, new hires lack the context of early struggles. To preserve the original culture, formally document and share stories of early failures, pivots, and near-death experiences during onboarding. This reminds everyone of the core principles that led to success.

To maintain its culture across 5,000+ employees, Canva identified 12 skills embodying success. These are codified and woven into every part of the employee lifecycle, from onboarding to performance reviews, ensuring consistent cultural alignment as the company grows.

To ensure cultural consistency while scaling, A16Z codifies its values in a document that every new hire must sign. This is followed by a personal one-hour briefing from a co-founder, making the culture explicit and non-negotiable from day one.

To ensure cultural consistency during its European expansion, the firm implements a structured program, including mid-level staff rotations, US leadership actively supporting the new team, and mandatory in-person meetings every other month. This treats culture as a tangible asset that must be actively managed and transferred.

Brands meticulously map the customer journey but often ignore the employee experience. To build a strong culture, apply the same brand principles to every employee touchpoint—from the job offer to their first day—to ensure everyone is aligned and delivering on the brand's promise.

'Culture add' is insufficient if new hires with different perspectives remain siloed. The goal should be 'culture multiply,' fostering intentional interaction and mutual influence between new hires and the existing culture. This creates a dynamic tension that fosters growth, rather than just filling a gap.

A Swedish saying about working hard ("blood smock") was translated literally into an intense, vampire-esque motto. Legora embraced this misunderstanding, fostering a high-intensity culture that they now see as a key differentiator.

To protect a distinct and powerful culture at scale, a firm should avoid hiring senior leaders from the outside. Instead, hire talented people earlier in their careers and grow them into the firm's specific ways of operating, ensuring cultural alignment for the most critical roles.
