When Does a Seed/Series A Startup Actually Need a Fractional CTO?
Fractional vs full-time CTO vs neither — honest fit criteria for post-seed founders with 2–15 engineers who need senior judgment without a $200k+ hire.
Short answer
When you have engineers shipping product but no senior eng leader for architecture calls, hiring calibration, and unblocks — and you're not ready to pay $200k+/yr for full-time.
Fractional CTO fits when
Typical pricing: $800/mo (weekly call + async) or $2k/mo (embedded 1 day/week).
- 2–15 engineers, post-seed through Series A
- Lead engineer is strong but stuck on a hard architectural decision
- Investors want a credible technical narrative before the round
- You need ~half a day/week of senior judgment, not daily management
Full-time CTO fits when
- 15+ engineers needing daily leadership and org design
- Delivery velocity is the bottleneck, not specific technical decisions
- You need someone accountable for the whole eng org
Neither fits when
I'm Muneeb Hussain — currently Head of Engineering (12 engineers, production AI), not an ex-CTO advising from memory. Happy to disqualify honestly on a 30-min call.
- You need production code written as the primary deliverable → hire engineers
- You want autonomous AI agent magic → wrong advisor
- You only offer equity, no cash retainer → usually pass
