It is significantly more difficult to step in as a non-founder CEO than to build a business from scratch. The new leader must contend with inherited business inertia, a pre-existing culture shaped by the founder, and constant comparisons, making transformative change much harder.

A16z's foundational belief is that founders, not hired "professional CEOs," should lead their companies long-term. The firm is structured as a network of specialists to provide founders with the knowledge and connections they lack, enabling them to grow into the CEO role and succeed.

For a controversial strategic shift, a co-founder's "moral authority" is invaluable. They can absorb the risk of looking foolish and give up their responsibilities ("Legos") to spearhead a new initiative. This allows them to champion a new direction with a level of credibility that can overcome internal skepticism.

The most common failure mode for a founder-CEO isn't a lack of competence, but a crisis of confidence. This leads to hesitation on critical decisions, especially firing an underperforming executive. The excuses for delaying are merely symptoms of this confidence gap.

When a founder advises a successor to 'make decisions that energize you,' it's a strategic directive, not a wellness tip. It serves as a guardrail against the 'death by a thousand cuts' that comes from compromising core beliefs just to make others comfortable, thereby preserving the vision.

All founders make high-impact mistakes. The critical failure point is when those mistakes erode their confidence, leading to hesitation. This indecisiveness creates a power vacuum, causing senior employees to get nervous and jockey for position, which spirals the organization into a dysfunctional, political state.

Founders often chase executives from successful scaled companies. However, these execs can fail because their experience makes them overly critical and resistant to the painful, hands-on work required at an early stage. The right hire is often someone a few layers down from the star executive.

Successor CEOs cannot replicate the founder's all-encompassing "working memory" of the company and its products. Recognizing this is key. The role must shift from knowing everything to building a cohesive team and focusing on the few strategic decisions only the CEO can make.

The ambition to be a CEO isn't just about leadership; it's a practical blend of ego, a need for control, and financial motivation. Critically, it stems from a deep-seated belief in one's own judgment and risk appetite, especially during pivotal market shifts that require bold, swift action.
