Dario Amodei states that at Anthropic's scale (2,500 people), his most leveraged role is not direct technical oversight but maintaining culture. He achieves this through intense, direct communication, including a bi-weekly, hour-long, unfiltered address to the entire company to ensure everyone remains aligned on the mission and strategy.

Address cultural issues by applying product management principles. Use surveys to gather data and identify pain points, then empower the team to propose solutions. Test these ideas like product features and iterate based on what works, making culture-building a shared, active process.

Create a public document detailing your company's operating principles—from Slack usage to coding standards. This "operating system" makes cultural norms explicit, prevents recurring debates, and allows potential hires to self-select based on alignment, saving time and reducing friction as you scale.

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.

The cultural gap between a domestic remote and an international remote team is much smaller than the gap between in-person and remote work. Effective global culture relies on the same principles as any remote team: solid communication, regular check-ins, and finding common ground.

Global teams miss the spontaneous chats of co-located offices. Leaders can fix this by formally dedicating 5-7 minutes at the start of meetings for non-work check-ins. This "structured unstructured time" materially improves team cohesion, performance, and long-term collaboration, making the perceived inefficiency highly valuable.

Culture isn't an abstract value statement. It's the sum of concrete behaviors you enforce, like fining partners for being late to meetings. These specific actions, not words, define your organization's true character and priorities.

Instead of vague values, define culture as a concrete set of "if-then" statements that govern reinforcement (e.g., "IF you are on time, THEN you are respected"). This turns an abstract concept into an operational system that can be explicitly taught, managed, and improved across the organization.

Culture isn't about values listed on a wall; it's the sum of daily, observable behaviors. To build a strong culture, leaders must define and enforce specific actions that embody the desired virtues, especially under stress. Abstract ideals are useless without concrete, enforced behaviors.
