Signs You Need a Fractional CTO
Your developers are busy, but releases keep slipping and nobody can say why.
You are about to raise and investors will ask who owns the technology.
You are choosing between agencies, freelancers and hiring, with no one technical to judge them.
The architecture worked for the MVP and is starting to crack under real users.
Your CTO search has dragged on for months and the roadmap can't wait.
An AI-built prototype needs to become a product real customers can trust.
You don't need another developer. You need someone who owns the technology.
What a Fractional CTO Does
The Whole CTO Role, Part-Time
Not advice from the sidelines. Decisions, ownership and accountability for how your technology gets built.
Ongoing Tech Leadership
10-20 hours a week inside your leadership team: architecture decisions, sprint and release oversight, vendor management and weekly steering.
Engineering Hiring
Define the roles, write the job descriptions, run technical interviews and build a team that stays and ships on schedule.
Architecture & Scaling
Find the bottlenecks before your users do, and get a roadmap that carries the system through the next stage of growth.
Technical Due Diligence
Pre-investment or pre-acquisition review of code, team and infrastructure, delivered as a written risk report in about a week.
Why Fractional?
Fractional vs Full-Time CTO
Before Series B, most startups need the strategic layer of a CTO, not 60 hours a week of it.
| Factor | Full-Time CTO | Fractional CTO |
|---|---|---|
| Annual cost | $300K-$450K+ | 70-80% less |
| Time to start | 3-6 months | 1-2 weeks |
| Commitment | Full-time, plus equity | 10-20 hrs/week, scale up or down |
| Wrong-hire risk | 6-12 months lost | Ends with notice |
| Experience | Varies by hire | 14+ years, 40+ companies |

When You Shouldn't Hire Me
If engineering is your core moat and you're past roughly 15 engineers, you need a full-time CTO's daily presence, and I'll help you hire one. If what you actually need is another senior developer, hire that directly; it's cheaper.
You'll hear that on the first call. My 100% job success rate depends on taking only the work I can deliver.
