CTO Advisory

CTO-level judgment. Without the hire.

Senior CTO judgment without a full-time hire. A named advisor reads your stack early and delivers board-ready output in a scoped engagement.

What it is

Senior judgment with accountability attached.

A fractional CTO is part-time senior technical leadership with CTO-level accountability, without a full-time executive hire.

It differs from an interim CTO and from pure consulting. A fractional CTO stays accountable for decisions and what happens next, not just recommendations.

The role is strategic and operational: platform and tooling decisions, vendor evaluation, board reporting, and keeping the technical plan tied to business goals.

Signs you need one

Three situations where a fractional CTO changes the outcome.

Most EU SMEs reach one of these three moments before they have a technical leader in place. Each one is recoverable, but only if the right judgment enters the room before the decision is made.

01

Making platform decisions without a senior technical voice

Decisions are being made by demos and sales decks, not senior technical judgment. Risk rises when no one can price long-term impact.

02

A raise or acquisition is opening the data room

Fundraising exposes architecture, cloud cost, GDPR posture, and key-person risk. You need senior leadership before the data room opens.

03

Tech debt is outpacing delivery

Delivery slows because debt compounds faster than it gets reduced. Without someone owning the technical direction, every release gets harder.

What they do. and do not do

Set expectations before you start the search.

What a fractional CTO does not do

Not this

  • A project manager who tracks sprint velocity
  • A senior developer who writes production code
  • A vendor or implementation partner with a preferred stack
  • A consultant who delivers a deck and disappears
  • An interim hire who needs a desk and a contract
What they deliver

This. with names on it

  • Architecture review against your 18-month roadmap
  • Vendor and tooling evaluation with no commercial affiliations
  • Board-ready reporting written for non-technical founders
  • Hiring brief when you are ready to recruit a full-time CTO
  • Security and GDPR posture assessment before a raise
  • Build vs buy recommendation as a written memo
What to demand from a provider

Questions to ask before you sign.

The fractional CTO market has no barrier to entry. Anyone can call themselves one. These questions separate operators from label-wearers.

?
Do you carry commercial relationships with the vendors you recommend? (If yes, walk away.)
?
Will you read our codebase and infrastructure before you give us a recommendation?
?
Who is the named person on this engagement, and will that person be available throughout?
?
What does the deliverable look like: a memo, a deck, a spreadsheet? Can we see a redacted example?
?
What happens after the engagement? Do you hand off, disappear, or stay accountable for implementation?
How we do it

Three things we do differently.

Named lead

One person. Direct line

You talk to the same advisor from the first call through delivery. No account layer. No handoff once the retainer starts.

Read first

We read the codebase before the kickoff call

Our advisory starts from evidence, not assumptions. We review your systems, your docs, and your vendor contracts before we give an opinion on anything.

Fixed scope

Fixed-fee where the scope holds

Most engagements run 2–6 weeks with clear deliverables and exit criteria. We do not run open-ended retainers that expand without accountability.
