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.

Leaders struggling with firing decisions should reframe the act as a protective measure for the entire organization. By failing to remove an underperformer or poor cultural fit, a leader is letting one person jeopardize the careers and work environment of everyone else on the team.

A kind culture must be actively protected. How a company handles high-performing but unkind employees reveals its true values. Prioritizing cultural integrity by addressing or removing these individuals sends a powerful signal that kindness is non-negotiable, even at a potential short-term cost.

To scale from 100 to 1,000+ employees, you must stop interviewing everyone. Success depends entirely on the cultural foundation built with the first 100 people. By personally hiring and imbuing them with the company's core values, you create a group of leaders who can replicate that culture as the organization expands.

When facing emotionally difficult decisions like firings or reorgs, it's tempting to optimize for making people happy. The correct mantra is 'serve the business, not the people.' A successful business ultimately benefits everyone involved. This principle provides clarity and helps you make the right, albeit painful, call.

A senior hire was instrumental in getting Snowflake's CRO promoted. Eighteen months later, that same person was found to be 'cancerous to the organization.' The CRO had to fire them and go on an 'apology tour,' a painful but necessary act of leadership to protect the company culture.

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.

Your culture isn't what's on the walls; it's defined by the worst behavior you allow. Firing a high-performing but toxic employee sends a more powerful message about your values than any mission statement. Upholding standards for everyone, especially top talent, is non-negotiable for a strong culture.

A company's culture isn't its mission statement; it's the worst behavior it's willing to accept. High-integrity employees will leave a toxic environment, while transactional, self-serving employees who tolerate anything for a paycheck will stay. This selection process causes a continuous erosion of culture.
