The core difference between a founder and a professional manager is their focus. Founders hold themselves responsible for outcomes, which is their source of power. Managers often care more about process and appearances, because managing process is their source of power.

The ultimate differentiator for CEOs over decades isn't just product, but their skill as a capital allocator. Once a company generates cash, the CEO's job shifts to investing it wisely through M&A, R&D, and buybacks, a skill few are trained for but the best master.

Unlike in big tech where CPOs can be purely visionary, startup CPOs must constantly shift their focus between strategy and execution. This 'pendulum' might swing from 80% strategy in the beginning to 80% execution pre-launch, requiring hands-on leadership to be effective.

Voyager CEO Al Sandrock, a physician-scientist, found his biggest challenge wasn't R&D but the business side. For pre-revenue biotechs, managing cash runway is the primary survival skill, requiring new CEOs to quickly learn finance from mentors and board members.

The early-stage CEO role involves extreme context switching. The key skill isn't just multitasking, but correctly identifying the single biggest impediment to growth—be it product, sales, or recruiting—on a weekly or monthly basis and focusing all energy there to solve it.

The title "CEO" is misleading. A founder's real job is to be a firefighter, constantly on call to handle unexpected crises, from employee emergencies to losing major clients. This mindset shift from strategic leader to crisis manager better reflects the reality of entrepreneurship and its inherent volatility.

Archer's CEO conceptualizes his role as being in the 'time business.' He views capital raised as a representation of time for his team. His high-stakes travel and meetings are strategically chosen only if they secure outcomes that extend the company's runway, enabling the team to solve hard technical problems.

The transition from founder to CEO shouldn't temper the core belief that your company can create massive change. That passion must remain. What should evolve is the execution strategy—moving from pure intuition to structured planning, financial literacy (e.g., understanding a P&L), and leveraging past experiences.

An engineering background provides strong first-principles thinking for a CEO. However, to effectively scale a company, engineer founders must elevate their identity to become a specialist in all business functions—sales, policy, recruiting—not just product.
