- What does a fractional CTO actually do?
- Senior technical leadership without the full-time price tag. Specific deliverables: technical strategy + roadmap, architecture decisions, hiring + team leadership, vendor + tool selection (cloud, AI, dev tools), code review on critical decisions, and sometimes hands-on code for high-leverage features. 10-20 hours/week is the typical commitment.
- How much does a fractional CTO cost in 2026?
- $5K-$15K per month for a monthly retainer (10-20 hrs/week). Hourly rates run $150-$350/hr for mid-market generalists, $300-$500/hr for senior specialists. Project-based engagements run $25K-$100K for 4-16 week scopes.
- When should I hire a fractional CTO?
- When your business has a technical product but you can't justify a $250K full-time CTO yet. Typically: $1M-$25M revenue, 1-3 person engineering team, founder isn't technical, or technical decisions are starting to bottleneck the business. Skip if you have 40+ hrs/week of ongoing CTO work — at that point, hire full-time.
- Fractional CTO vs full-time CTO — which do I need?
- Fractional for businesses under $25M ARR or pre-Series A. Full-time when you need 40+ hours/week dedicated focus, complex engineering org leadership, or board-level technical representation. A common path: fractional for 6-12 months while you build the team, then hire full-time when the workload justifies it.
- How do I vet a fractional CTO?
- Ask: (1) Show me 3 specific technical decisions you made for a recent client that paid off. (2) What's your typical engagement structure and pricing? (3) Have you led an engineering team of 5+? (4) What's your AI/LLM hands-on experience in 2026? (5) Can I talk to 2 past clients? Anyone who can't answer #1 with specifics is selling strategy not leadership.
- Is a fractional CTO different from an AI consultant?
- Yes. AI consultants build specific AI features. Fractional CTOs lead technical strategy across the entire tech stack — including AI but also infrastructure, team, vendor decisions, hiring, code review. Some fractional CTOs specialize in AI (like Chief AI Officer roles); most cover the broader technical leadership scope.
