Individual contributor B2B sales roles attract high applicant volume across most markets, because sales is one of the most measurable and transferable functions and experienced sellers move between companies regularly. The market thins considerably at the VP Sales, Head of Sales, and Chief Revenue Officer level, however. These roles require a specific combination of personal quota attainment history, team leadership experience at scale, and the organizational capability to build or rebuild a revenue function from a given stage of company maturity. Companies hiring a VP of Sales for a Series B SaaS company and a VP of Sales for a mature enterprise software vendor are looking for fundamentally different profiles, and candidates who do not calibrate to stage are eliminated early. The qualified pool for stage-appropriate senior sales leadership is smaller than the title frequency on job boards suggests.
