The most important factor is matching the hire to your current stage. Early-stage companies need a builder — someone who can create process from scratch and operate in ambiguity. Mid-stage companies need a scaler — someone who can run a team and optimize an existing playbook. Hiring a scaler too early (or a builder too late) is the most common GTM hiring mistake. Define the specific outcome you need the hire to produce in their first 90 days before you post the role.
