Financial results are a downstream outcome. The true upstream driver is a company's culture—its talent density, hiring practices, and incentive systems. A strong culture creates a reinforcing feedback loop that attracts talent, improves decisions, and fuels compounding for decades.

Dario Amodei states that at Anthropic's scale (2,500 people), his most leveraged role is not direct technical oversight but maintaining culture.

CEO Will Kane recounts how former President Jimmy Carter told Pfizer employees that every job, from CEO to the mailroom, is integral. This message of universal importance, coming from a respected outsider, can be more powerful for building a unified culture than similar messages from internal leadership.

Developing a new medicine is 'the toughest team sport,' requiring hundreds of people across diverse disciplines over many years. In this context, culture isn't a perk; it's the fundamental 'glue' that enables these disparate teams to work in concert and succeed. Without it, even the best individual players will fail.

Leadership is not a soft skill but a critical function that creates a culture to get the most out of a company's tangible and intangible assets. Oaktree views quality management as essential for maximizing profits and will replace leadership when necessary. This perspective frames culture not as a byproduct of success, but as a direct prerequisite for it.
