Savings at each engagement level
Compared to a full-time CTO at Seed stage:
- Advisory level: Save $270,000–$475,000/year
- Strategic + embedded: Save $190,000–$380,000/year
- Near full-time: Save $70,000–$260,000/year
Even the most expensive fractional CTO engagement saves $70,000+/year vs a full-time hire — while giving you access to someone who has done this 5–10 times before across multiple startup cycles.
When the full-time CTO makes financial sense
The math flips when:
- You have 10+ engineers who need daily executive oversight
- You've raised Series B+ and can absorb the headcount cost
- The CTO will be a board member or investor-facing executive
- Your product requires proprietary research-level technical depth that needs full-time focus
