To avoid the trap of hiring 'good enough' people, make the interview panel explicitly state which current employee the candidate surpasses. This forces a concrete comparison and ensures every new hire actively raises the company's overall talent level, preventing a slow, imperceptible decline in quality.

Treat hiring as a compounding flywheel. A new employee should not only be a great contributor but also make the company more attractive to future A-players, whether through their network, reputation, or interview presence. This focus on recruiting potential ensures talent density increases over time.

Over a long career, great leaders accumulate a "snowball of talent"—A-players who follow them from one venture to the next. This becomes a powerful litmus test when hiring executives: if they have no network of past colleagues eager to join them, it's a major red flag about their leadership ability or the quality of their past teams.

The difference between a true partner and an employee is whether you seek their counsel on complex problems. If you consistently go to them for advice when you're unsure, they're a partner. If you only give them direction, they are not a "thought partner," which is a red flag for a C-level executive role.

To gauge if your culture supports momentum, observe your top performers during a colleague's celebration. True A-players will be at the front, celebrating. If they're resentful in the back, you have a culture of 'I-centered' individuals that will kill collective momentum.

To clarify difficult talent decisions, ask yourself: "Would I enthusiastically rehire this person for this same role today?" This binary question, used at Stripe, bypasses emotional ambiguity and provides a clear signal. A "no" doesn't mean immediate termination, but it mandates that some corrective action must be taken.

Employee retention now requires a customized approach beyond generic financial incentives. Effective managers must identify whether an individual is driven by work-life balance, ego-gratifying titles, or money, and then transparently tailor their role and its associated trade-offs to that primary motivator.

Your internal monologue during hiring reveals if you're making the right choice. If you think, "I really need to fill this role," you're on the path to settling. The right candidate sparks the feeling of, "I don't even care if I have a role for this person, I have to get them in."

True A-players are 'undeniable' drivers whose impact is immediately obvious. If you find yourself constantly wondering or second-guessing if someone is the right fit, they are a B-player. Trust that indecision as a signal to cut them fast, as B-players create drag on the entire team.
