Three Series B founders in Guadalajara. Each built product-market fit through sheer force of will. Each hired seasoned operators to scale what they'd created. Each watched those hires fail within nine months. The hires weren't wrong. The timing was. Founders thrive in Founder Mode—direct control, immediate decisions, instincts calibrated for chaos they can touch. But Series B shifts the conditions entirely. The founder calibrated for tight corners suddenly enters high-speed straights, still braking for corners that no longer exist. The Founder's Paradox™ names this pattern: the fierce control that built the company becomes the ceiling that prevents it from scaling. The pit window opens at Series B. Not every founder needs to step out entirely—but ignoring the calibration mismatch guarantees a revolving door of C-suite hires who "just didn't work out."

our CFO spent three hours yesterday reconciling expense reports. Your VP of Engineering is personally reviewing every pull request. Your CTO is troubleshooting a customer's API integration. Welcome to Series B, where your C-suite has become the world's most overqualified middle management team. I see this pattern constantly in growth-stage companies. The org chart looks impressive. Strong executives at the top. Talented individual contributors doing the work. But between them? A hollow layer where directors and senior managers should be. McKinsey research shows investors attribute 65 percent of portfolio company failures to people and organizational issues. The most common structural failure? The missing middle. McLaren F1 spent half a decade learning this lesson the expensive way before restructuring their technical leadership. Your Series B doesn't have that kind of time.
