Fractional CTO, UK

UK-based fractional CTO for founders who need senior technical leadership without a full-time hire.

Architecture decisions, hiring, engineering culture, and hands-on delivery - for startups and scale-ups across London, Manchester, and remotely UK-wide.

Already built something and want to know if it's solid first? That's an audit, not a hire - I do both.

Good Fit For

Four situations where a fractional CTO earns its cost.

Pre-hire

You need technical direction now, before you can justify - or find - a full-time CTO.

Founding team gap

The founding technical team is strong on delivery but needs a senior partner for architecture and hiring calls.

At a crossroads

A platform rewrite, cloud migration, or new product line - decisions that are expensive to get wrong.

CTO gone commercial

Your technical co-founder moved into a business role and the technical side needs someone hands-on again.

What's Included

What a fractional CTO from me actually does.

Senior technical leadership without the full-time hire. I work with your team to set technical direction, make architecture decisions, hire and grow engineers, and build the systems that let you scale. A CTO who still writes the code and understands what your team is actually dealing with.

  • Startups needing technical leadership before hiring a full-time CTO
  • Scale-ups where the founding technical team needs a senior partner
  • Companies at a crossroads - platform rewrite, cloud migration, or a new product line
  • Businesses where the CTO has moved into a business role and the technical side needs someone hands-on
Pricing

Priced by how many days a week you actually need me.

Structured the way most UK fractional CTO engagements are actually scoped - by days per week, or as a fixed-term project.

TypeTimelineFrom
1 day/weekOngoing retainerFrom £3,500/month
2 days/weekOngoing retainerFrom £6,500/month
3 days/weekOngoing retainerFrom £9,500/month
Project / fixed-termScoped per projectFrom £1,500/day

Retainer pricing reflects ongoing weekly access and continuity, not a flat per-day rate - project work with no ongoing commitment is priced separately at the day rate. Every engagement starts with a free 30-minute call to work out which shape fits - retainer or fixed-term. For complex situations, a paid discovery session (£500) gets you a written assessment of the landscape within 1-2 working days, credited against the project if we proceed.

Proof

Recent engagement.

Led an early-stage SaaS startup from zero to pre-seed - architecture, stack decisions, MVP build, engineering culture - as sole technical leader. Also rescued a stalled .NET migration at Lancom Technology - six months overdue, back to billable within a month.

Not sure if this is fractional leadership or an audit?

Book the same 30-minute call either way. No pitch, no deck - I'll tell you honestly which one actually helps, and what it would cost.
