A CEO wears many hats—scientist, investor, operator—but their primary, non-delegable function is decision-making. This role requires integrating input from a leadership team that thinks at an enterprise level, enabling the CEO to make the final call on capital, strategy, and people.

A US President for a multi-therapeutic pharma company shouldn't aim to be an expert on every disease. Their primary job is to enable deep subject matter experts, get out of their way, and constantly ask the strategic question: "What's going to take us to that next threshold?"

The transition from a leadership role at a large pharma company like Gilead to a biotech CEO involves a massive shift in scope. Instead of managing one large function with a large team, a biotech CEO is hands-on with every aspect of the company, from science to finance.

A leader in a highly technical field doesn't need to be the deepest scientific expert. Venture capitalist Jeanne Cunicelli, who is not a scientist, succeeds by mastering the skill of deconstructing complex topics through persistent questioning and listening, enabling her to make sound judgments.

In a highly technical field, a leader's job is not to be the smartest person in the room. Instead, their role is to surround themselves with brilliant specialists, ask the right questions to connect disparate pieces of information, and guide the collective expertise toward a single, unified goal.

In the early stages, a biotech CEO's role is primarily scientific leadership and storytelling to attract investors. As the company and market mature, the role shifts. Effective CEOs must then become adaptable strategists, staying true to their core vision while responding to the dynamic industry environment.

Kevin Pojasek credits his effectiveness to a deliberate 12-year journey through diverse roles—investing, company creation, research, and clinical operations. This broad experience allows a leader to understand how all parts of the company, from high-level strategy to detailed science, fit together.

Beyond scientific knowledge, the most effective biotech CEOs possess a specific set of traits. They must be decisive, maintain ruthless capital discipline (even for small amounts), and consistently demonstrate strategic clarity, especially when facing the immense pressure inherent in the industry.

A CEO's role is seeing the same company through the different lenses of various stakeholders (investors, lawyers, scientists). Success requires learning the unique 'language' of each group—their incentives and communication styles—to effectively translate the company's vision and value proposition for each audience.
