Quick Answer

Hire a Fractional CTO if you're pre-Series A, need strategic guidance but not daily management, want to validate your tech direction before committing to a full-time hire, or need to stretch your runway.

Fractional CTOs typically cost $8,000-$15,000 per month, or $96,000-$180,000 annually. This is 40-60% less than a full-time CTO when you factor in salary, equity, benefits, and recruiting costs.
