## 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
