Fractional AI CTO
Senior technical leadership without a full-time hire. Architecture and code reviews, a straight answer on AI strategy, help choosing vendors, a roadmap that matches your stage, and mentoring for your engineers, on a month-to-month retainer.

You need the judgement, not the full-time salary
A lot of teams are at the point where technical decisions have real consequences, choosing a stack, evaluating an AI vendor, setting a roadmap, but not at the point where a full-time CTO makes financial sense. The result is that those decisions get made under-informed, or deferred. A fractional arrangement covers the judgement calls: regular reviews, someone to pressure-test a plan, and a steady hand mentoring the engineers you do have.
What the retainer covers
- Regular architecture and code reviews, with findings your team can act on
- AI strategy guidance: what is worth doing, what is hype, and what order to do things in
- Vendor and tool evaluation, so you are not choosing a platform on a sales call alone
- A technical roadmap matched to your stage, budget, and team size
- Mentoring for your engineers, raising the level of the team over time
- Availability for the decisions that come up between reviews

Questions we get about this
It is a retainer for judgement and guidance, not a full-time schedule. In practice that means a set cadence of reviews and check-ins plus availability for decisions in between. The exact shape is agreed at the start and adjusted as needs change.
