Quick answer
The CTO is responsible for technology vision, external positioning, and long-term technical strategy. The VP of Engineering is responsible for managing the engineering organization — delivery, process, hiring, and day-to-day execution. In many companies both roles exist; in early-stage companies, one person often covers both until the organization scales.
Many successful companies operate with a CTO-only model until 30–50 engineers, at which point a VP of Engineering becomes necessary. The roles are complementary: the CTO answers 'What should we build and on what technology?' while the VP of Engineering answers 'How do we build it reliably, at speed, with a healthy team?' Early-stage companies often need a CTO who can do both; scaling companies need to separate the functions.
