To succeed on an executive board, you must shed your functional hat. While you bring expertise from your area (e.g., marketing), your primary responsibility is to consider the health and growth of the entire company. A 'total company' perspective is essential for credibility and impact at this level.

A CMO's primary job is not just external promotion but also internal marketing. This involves consistently communicating marketing's vision, progress, and wins to other departments to secure buy-in, resources, and cross-functional collaboration.

The leap from a hands-on marketing leader to a C-level executive is less about tactical skills and more about personal growth. It demands a shift from execution ('doing the work') to leadership ('inspiring people'), which requires self-awareness, authenticity, and dropping 'professional walls' to build genuine connections.

Some CEOs encourage tension between sales and marketing. A more effective model is for the CRO and CMO to build enough trust to handle all disagreements—like lead quality or follow-up—behind closed doors. This prevents a culture of finger-pointing and presents a united front to leadership.

At the VP or C-level, a leader's primary role shifts from managing their function to driving overall business success. Their focus becomes more external—customers, market, revenue—and their success is measured by their end-to-end impact on the company, not just their team's performance.

Marketers have little direct authority and can be ignored by sales, engineering, or finance. Their power comes not from managing down, but from influencing peers ('sideways') and superiors ('upwards'). Success depends on building alliances and aligning goals with the broader organization.

Harvey's COO doesn't own a single function like GTM. Instead, she tackles complex, cross-functional initiatives that the CEO would otherwise have to lead. She manages stakeholders and synthesizes options, effectively acting as a clone of the CEO for driving company-wide strategic projects and increasing his leverage.

The transition to CMO is a shift from doing marketing to enabling it. Success requires mastering politics, finance, and cross-functional leadership. The best marketers often struggle because the job is more "Chief" than "Marketer."

A CMO's influence is often wielded covertly. By framing marketing goals in the language of other departments and allowing executives to believe ideas are their own, CMOs can navigate politics and implement their agenda successfully.
