Fractional CTO + AI Officer
Embedded part-time AI leadership for startups and SMBs — the highest-rate path

Why AI Expertise Is the Differentiator
- AI leadership roles grew 40-60% in fiscal year 2025
- Nearly half of FTSE 100 companies now have a Chief AI Officer (most appointed in the past year)
- 89% of executives view AI as a top priority, but fewer than 15% have a solid strategy or in-house CAIO
- Full-time CAIO: $350K-$500K base + equity. Fractional CAIO retainer: $15K-$30K/month (20-40% of full-time cash burn)

Case Study: Sergio Pereira
Featured in Pragmatic Engineer. Fractional CTO for 10+ companies since 2014. His first client in 2016, PakketMail, started for free — he helped hire 2 engineers and implement a vendor integration, then got paid after they received VC funding. The lesson: start with one or two engagements, prove value, let referrals compound.
Pricing Psychology
- Do NOT price by the hour (signals "developer for hire")
- Price by monthly retainer (signals "executive leadership")
- Frame cost against alternatives: "A full-time CTO costs $400K+/year. I deliver 80% of that value at 20% of that cost."
