What is a Fractional CTO?
A fractional CTO is a senior technology executive who leads a company's engineering and technical strategy part-time — typically 1–3 days a week. Unlike a consultant (who recommends and exits), fractional CTO jobs embed leaders in the leadership team: they own technical strategy and architecture, manage and hire engineers, install delivery cadence, run technical due diligence for fundraising, and are accountable for technology outcomes over time.
Fractional CTO jobs are most common when a technical founder needs senior leadership they can't yet justify full-time, or a non-technical founder needs someone to own the build. Day rates: typically £800–£2,000/day. Low end = solid senior engineering moving into leadership; high end = multiple CTO/VP-Eng roles, sector expertise, scaling track record. *Sources: Fractionus 'Fractional CTO: What They Do' 2026; fcto.uk 2026*

When to hire a fractional CTO
Strategic technology scenarios where experienced CTO leadership drives transformation without full-time executive commitment
Pre-fundraise technical due diligence
Due diligence
Defined engagement, high stakes — investors need to see robust technical foundations and scalability
Scaling team needs delivery cadence
Delivery process
Engineering growing faster than process — install structure that scales with team growth
Architecture / build-vs-buy decisions
Technical strategy
De-risk decisions that compound for years — platform choices, technical debt, scalability foundations
Daily hands-on ownership of large team
Honest caveat
If you need daily hands-on technical ownership of a large team, hire full-time

How vetting and placement works
Rigorous 5-stage process ensuring optimal technology leadership alignment and successful long-term engagements. Part of our specialist [fractional recruitment agency](/top-fractional-recruitment-agency) methodology.
A five-stage method for blended teams.
How we take a founder or board's brief and turn it into a delivery system across core, fractional, network, and outsourced functions.
CONFIRM — REAL PROCESS- 01
Diagnose the shape
Stage · pressure · the work nobody is doing.
We run The Team Architect on every brief. Stage, headcount, sector, pressure. The output is the org shape we'd build with you — including the seats to hold for now. We turn briefs down here, gracefully, when the answer is 'not yet'.
- 02
Scope the seats
Core. Fractional. Network. Outsourced.
Each function gets a verdict and an intensity. Engineering core. Finance fractional at 2.5 d/wk. Paid-media on the network. IT helpdesk outsourced. We commit to days, IR35 status, and replacement terms in writing before search starts.
- 03
Source the operators
Network-first. Outbound where it needs to be.
Fractional candidates have portfolios, not job alerts. We run from our own network plus a structured outbound for the senior end. Shortlist in 8–12 days. Honest scoring against the rubric — no padding.
- 04
Embed the engagement
First-week plan. Success criteria. IR35 live.
Calibration calls. Onboarding plan written down. IR35 structure live before day one. We sit in the first cross-functional meeting if it helps. The replacement guarantee runs for 90 days.
- 05
Manage the workforce
Quarterly cadence. Bridge to core when right.
Monthly check-ins for the first quarter, quarterly after. We surface when a fractional should convert to core (Series A → Series B finance is the modal moment) and we own the bridge. Replacement, conversion, off-ramp — it's all the same firm.
