The agency
What fractional CTO firms actually do
Every claim on a card links to the page that states it; anything a firm does not publish about itself is left out. If you would rather brief one firm, we come back with a shortlist of 3–5, each with rate, availability and IR35 position set out.
Fractional CTO firms provide a chief technology officer for part of the week, to own the technology direction, the architecture and the engineering team. Some place a CTO from a bench and stay involved; some are small practices where a named executive does the work.
This page lists the firms. For how to hire a fractional CTO, see hire a fractional CTO; for the business’s own IT rather than the product, see fractional CIO firms.
The firms below are fractional CTO providers, profiles rather than a ranking: no firm here publishes the audited outcomes a league table would need, and we are one of the firms.

Fractional CTO firms: the firms, on their own facts
Numbers show position on this page — they are not a ranking. Every fact on a card comes from that firm’s own site, linked; anything a firm does not publish about itself is left out.
- 01 / THE PUBLISHERFractional QuestThe publisher of this page — listed first because it is ours, not because it outranks the firms below. We recruit fractional, interim and permanent CTOs. You bring a brief; we come back with a shortlist of 3–5, each with day rate or salary, availability and IR35 position set out, after five-stage vetting. We hold no candidate bench and publish no placement record.

The scope
How to choose between fractional CTO firms
The fee basis, in writing. Retained search firms are paid in staged instalments whatever the outcome, and work exclusively; contingent recruiters are paid only if their candidate is hired, often non-exclusively; interim and fractional providers usually charge through the day rate or a retainer. Ask for the basis and when each payment falls due, in writing. We publish no fees: ours are agreed in writing per engagement.
Who vets, and how. Ask who runs the search day to day — at a retained firm, the partner who wins the brief is not always the person who calls candidates — and what each candidate is tested on beyond the CV. Our five-stage vetting is published.
What comes back. Named candidates with a rate or salary, availability and an IR35 position — or a database, a longlist or a marketplace to browse? Ours is a shortlist of 3–5.
IR35 on every brief. For an interim or fractional executive working through their own company, the off-payroll rules decide how the engagement is taxed, and a medium or large client makes the status determination (HMRC). Ask for the IR35 position on the brief, not after the contract.
Retained, contingent or day rate. Retained search for a permanent, board-level appointment; contingency for a role below the board with many candidates; interim for full-time cover for a fixed term; fractional for senior judgement on part of the week.
The process
How does a brief become a shortlist?
Six steps, one accountable person at each. We don’t promise a shortlist by a date; the weeks below are what a well-scoped brief usually takes.
- Day 001The 15-minute callThe seat, the engagement shape, the days or hours, the start date and the budget. No account needed; a call or a written brief.You and us
- Week 102Scope agreed in writingThe outcome the seat exists for, which days, and how the engagement will run for IR35. A brief that describes a person rather than a job, we rewrite with you.Us
- Weeks 1–203Search and approachWe approach people who aren’t looking and verify prior tenure in the seat at your scale and stage.Us
- Weeks 2–304References, taken by usFrom recent clients and boards: what they delivered, not what they titled it.Us
- Week 305Shortlist of three to fiveEach with day rate or salary, availability and IR35 position set out. You interview and decide.You
- Week 406Kick-offScope, first-month outcomes and the contract agreed before day one.You, them and us
Your figures
What does part of a CTO’s week cost?
Rate × days × weeks, against a loaded full-time package. Move the sliders; the numbers redraw.
- CTO band £1,000–£1,600 (Leadership Services 2026)
Year-one cost, fractional
£119,600
Fractional costs less in year one by£64,225
Our arithmetic. £160,500 Robert Half 2026 median salary + employer NI at 15% above £5,000 (HMRC) = £183,825. Excludes pension, bonus and any search fee.

Fractional CTO firms: how the models compare retained, contingent, interim or fractional
The firms on this page work in one or more of these models. Ask which one a firm proposes for your brief.
| Fractional Quest (the publisher) | Retained search firm | Contingent recruiter | Interim provider | Fractional provider | |
|---|---|---|---|---|---|
| How it is paid | Agreed in writing per engagement | Staged instalments, whatever the outcome | Only if its candidate is hired | Usually through the day rate | A retainer or day rate, or a placement fee |
| Exclusivity | One brief, one shortlist | Exclusive to one firm | Usually non-exclusive | Varies | Varies |
| Engagements | Fractional, interim, part-time, permanent | Permanent, sometimes interim | Mostly permanent | Full-time for a fixed term | Part of the week, ongoing |
| What comes back | A shortlist of 3–5, each with rate, availability and IR35 position | A shortlist from a researched market map | CVs of available candidates | Available interims matched to the brief | A matched leader, or a marketplace to browse |
| Best when | You want options across engagement shapes | A permanent, board-level appointment | A role below the board with many candidates | The seat is empty or a change needs leading now | You need senior judgement, not five days |

The decision
Which of the fractional CTO firms fits your brief
Match the firm to the hire, not the other way round.
- Non-technical founderTechnical decisions with nobody to own themA fractional CTO to own architecture, suppliers and the first engineering hires.
- Before a raiseInvestor questionsA fractional CTO to answer technical due diligence and set the roadmap.
- Between CTOsThe seat is emptyAn interim CTO full-time until the permanent hire — several firms here offer both.
Vetting
How do we vet an executive?
Five stages before anyone reaches a shortlist of three to five.
- Pedigree screenTenureWe verify prior tenure in the seat, at the scale and stage you need. No consultant presenting as an executive.
- Mandate fitFitFit to your stage, sector and the problem the seat exists to solve, not a CV keyword.
- Reference deep-diveVerifyWe take references ourselves, from recent clients and boards: what they delivered, not what they titled it.
- ShortlistShortlistThree to five candidates, each with day rate, availability and IR35 position set out.
- Kick-offStartScope, first-month outcomes and the contract agreed before day one.
The full process is on how we vet.
which kind of firm
Fractional CTO firms: which kind of firm fits and which page to read next
The fractional CTO firms above work in the models set out in the comparison table — retained search, contingent recruitment, interim provision and fractional provision — and several work in more than one. Start with the hire: permanent or a phase, board level or below, five days or part of the week. Then ask each firm which model it proposes for your brief, and why.
If you would rather brief one firm for every shape of the seat, book a call: we recruit fractional, interim, part-time and permanent executives, and the brief decides the shape.
Whichever you brief, the same law applies: the Employment Agencies Act and the Conduct Regulations cover executive search consultants as well as agencies, a firm must not charge a candidate for finding them work, and the fee you pay is a commercial agreement between you and the firm (gov.uk guidance on the Conduct Regulations).
method
How this list is built and what it is not
Own-site facts only. Each firm is profiled from its own website, read on 23 October 2026, or from a primary register such as Companies House; every claim links to the page that states it. We do not repeat a firm’s fees, guarantees, client names or self-descriptions such as “leading” or “number one”.
Not a ranking. Numbers show position on the page. No firm here publishes the audited outcomes a ranking would need, and we are one of the firms — listed first because the page is ours.
Independence. Fractional Quest takes no referral fees from any firm listed, and none of them is a partner or client. Other fractional CTO firms exist; we add a firm only when its own site gives us facts to state.
The right route
Agency, recruiter, interim or permanent?
Three taps. Say how much senior work there is, for how long, and whether it is one leader or a run of hires; the tool names the route.
The route · Fractional recruiter
An embedded fractional recruiter.
A hiring plan to work through below the leadership team is a talent-acquisition job: a recruiter inside your business for part of the week, paid for their time. We don’t supply them; the page below explains the role.
The route · Non-executive director
A non-executive director.
Independent oversight and constructive challenge, not executive direction. We recruit NEDs through the same brief process.
The route · Advisor
An advisor, not yet a seat.
Less than a day a week of senior input is advisory. Buy it as a scoped engagement; when it grows into a day or more, brief us for a fractional executive.
The route · Interim
An interim executive.
Four or five days for a fixed period is interim: cover for a departure, a turnaround or a transaction. The IIM puts the UK average at £907 a day and ten months.
The route · Permanent
A permanent search.
Four or five days of work, ongoing, is a full-time seat. We recruit permanent executives through the same brief process.
The route · Fractional executive
Brief a fractional recruitment agency.
Senior judgement for part of the week: a fractional CFO, CTO, CMO or COO on one to three days. We come back with a shortlist of three to five, each with day rate, availability and IR35 position set out.
We recruit executives. We don’t supply embedded fractional recruiters; where that is the right route, the tool says so.

Questions
Fractional CTO firms questions, answered
Fractional CTO firms provide a chief technology officer for part of the week, to own the technology direction, the architecture and the engineering team. Some place a CTO from a bench and stay involved; some are small practices where a named executive does the work.
From firms whose own sites describe the service, profiled only from what each publishes about itself, each claim linked. It is not a ranking: no firm publishes the outcomes a ranking would need, and we are one of the firms, listed first and marked as the publisher.
Retained search firms are paid in staged instalments whatever the outcome; contingent recruiters only if their candidate is hired; interim and fractional providers usually through the day rate or a retainer. None of the firms on this page is profiled on its fees. Ask any firm for the fee basis in writing. Ours is agreed in writing per engagement.
Ask each firm who runs the search day to day and what each candidate is tested on. We put every candidate through five-stage vetting — pedigree screen, mandate fit, references we take ourselves, shortlist and kick-off — and send a shortlist of 3–5, each with rate, availability and IR35 position set out.
A fractional CTO works part-time on a rolling basis; an interim CTO works full-time for a fixed term to cover a gap or carry a critical change. Several firms on this page provide both.
It depends what you want. Some providers offer leadership only and state they take no development revenue; others pair leadership with delivery. Ask which you are buying, and who decides build against buy.
We are one of the firms on this page, and its publisher. We recruit fractional, interim and permanent CTOs. We take no referral fees from any firm listed.
