There is no single path, but most CTOs arrive through one of a few well-worn routes. The common thread is a combination of strong technical foundations and leadership ability.
Common paths

1. FOUNDER → built the product, grew with the company
2. IC → LEAD → MANAGER → DIRECTOR → VP → CTO (climbing the org ladder)
3. ARCHITECT / PRINCIPAL → CTO (deep technical authority, then breadth)
4. LATERAL → senior engineering leader hired in as CTO
