CTO (Chief Technology Officer)
Owns the company's technology strategy: architecture, org, hiring and tech/business alignment.
Why this hire matters.
The CTO holds your ability to build and keep the product promise over time. Early on, they code and lay the foundations that will decide your scalability (and your debt) for years. In a scale-up, the role shifts: hire and structure engineering, arbitrate build vs buy, secure data and infrastructure, and speak to the board and investors. A weak CTO costs you in expensive rewrites, hiring failures, incidents and lost technical credibility during fundraises. A strong CTO turns technology into competitive advantage and valuation leverage. It's the most structural hire in the tech track: equity is often as decisive as base, and only pays off on collective success.
