This page sets out what the service covers, when part-time is the right shape, what the market publishes on rates, and how we come back with a shortlist of 3–5, each with rate, availability and IR35 position set out.

01/ the role
What part-time CTO services cover
A part-time CTO works set days each week for one organisation.
A part-time CTO works agreed days each week as a member of the leadership team, suited to a product with a stable team that needs consistent technical leadership rather than a full-time executive.
The service covers technical strategy and architecture decisions, building and leading the engineering team, delivery cadence, quality and engineering process, and security, scalability and technical debt and technical due diligence for investors or acquirers.
If you are weighing the options, the same seat is also bought as fractional CTO services, interim CTO services, outsourced CTO services, or permanent CTO search.
What the seat does day to day is set out in the CTO role explained; executives looking for this work can see current CTO roles; the full cost picture is on the CTO cost guide.
02/ scope
What is in scope — and what is not
In scope
Technical strategy and architecture decisions; building and leading the engineering team; delivery cadence, quality and engineering process; security, scalability and technical debt; technical due diligence for investors or acquirers.
Not in scope
Internal IT, end-user devices and business systems usually belong to a CIO or IT director.
Product discovery and roadmap ownership belong with a product leader, working closely with the CTO.
CTO or a neighbouring seat?
A CTO builds the product’s technology; a CIO runs the company’s own systems.
Early-stage businesses need the CTO first.
The scoping test: write down the three decisions you need the CTO to own in the next ninety days. If you cannot, you are not ready to brief.
03/ the week
How a week divides.
Part of a week is the point of the model: the days you buy are yours, the rest of the week goes to other clients. Move the days a week and the week redraws.
Illustration only: one way a part-time CTO’s week can divide at 2 days a week for you. Each block is half a day.
04/ the route
Fractional, interim or permanent?
Four taps. The answer names the route for the seat and the page that covers it.
The route · Fractional
A fractional CTO services.The work fills part of the week, so buy the days it needs.
A fractional CTO services holds the seat on agreed days for as long as the seat is needed, and works for other clients on the rest.
The route · Interim
An interim CTO services.The work fills the week, and it has an end: a programme, a cover, a transaction.
An interim CTO services takes the seat full time for that stretch and hands it over when it is done.
The route · Interim, then permanent
Interim now, a permanent CTO services after.The seat is full time and long term, and the need is now.
An interim CTO services holds it while the permanent search runs, so the seat is not left empty.
The route · Permanent
A permanent CTO services.A full-time seat that sits at the table for years is a permanent hire.
There is time to run a search, so run one.
05/ rates by stage
CTO rates what the published benchmarks say
Every figure is the named source’s own published band. Fractional Quest publishes no fees: each candidate on a shortlist states their own rate. A part-time employee is usually paid the permanent salary pro rata to the days worked; a part-time contractor is paid by the day.
06/ comparison
Four ways to buy a CTO fractional, interim, part-time or permanent
The same CTO seat can be filled four ways. The difference is commitment, contract and how long you need it.
07/ timing
When part-time CTO services are the right call
Three situations where the part-time shape beats the alternatives.
Scenario 01
Steady state
A part-time CTO works agreed days each week as a member of the leadership team, suited to a product with a stable team that needs consistent technical leadership rather than a full-time executive.
Scenario 02
Scope
The work — technical strategy and architecture decisions, security, scalability and technical debt — is regular and predictable, so a fixed pattern of days covers it.
Scenario 03
Retention
Many experienced chief technology officers choose part-time work for the long term; a part-time role can attract someone a full-time salary could not.

09/ how it runs
How a part-time CTO engagement runs from brief to hand-over
Brief.
You tell us the scope, the days each week and the start date, and what success looks like in the first ninety days.
A clear brief names the decisions the CTO will own.
Shortlist.
We come back with 3–5 part-time chief technology officers against the brief, each with day rate or salary expectation, availability and IR35 position set out, assessed through our five-stage vetting.
Rhythm.
A part-time CTO works best with the same days every week, so the team knows when decisions get made.
Agree in writing which meetings fall on their days and how urgent issues are handled on the others.
Hand-over.
If the seat grows into full-time work, the part-time CTO can help recruit the permanent successor, or convert themselves.
