What is a fractional CTO?

A senior technology leader who works with your business part-time — typically a few days a month — owning the decisions a full-time CTO would: architecture, technical hiring, vendor and budget oversight, and how technology serves the business plan. You get the judgement without the full-time cost.

Fractional, interim or part-time CTO — which do I need?

It's mostly duration and cause. An interim CTO covers a gap — a departure, a transition — full-time but short-term. Fractional (or part-time) is ongoing but partial: a few days a month, indefinitely. If you're not replacing anyone and just need senior direction, fractional is usually the answer.

How much does a fractional CTO cost?

It's priced by engagement shape, not salary. The two common shapes are an advisory cadence — regular sessions, decisions reviewed, on call for the big calls — and a hands-on arrangement where the CTO runs your developers, hiring and vendors day to day. Ours start from £3,000 a month for advisory, £8,000 a month hands-on, both rolling.

What is CTO as a service?

Another name for the same idea — senior technical leadership bought as a service rather than a hire. Some providers wrap it in productised tiers; ours is a person with a cadence, because leadership doesn't come in a box.

Do I need a fractional CTO?

Ask what's blocked. If technical decisions are stalling — an architecture nobody will commit to, hires you can't assess, vendors you can't challenge — a few days of senior judgement a month unblocks a lot. If your product simply needs more building, you don't need a CTO; you need hands.

What if we need developers rather than direction?

Then don't hire leadership. Staff augmentation puts vetted engineers inside your team under your management; a dedicated team gives you a whole delivery group managed by us. A fractional CTO pairs well with either — direction from one, delivery from the other — but they're different purchases.

Every step, with a team who's done it before

A fractional CTO earns its keep in the decisions, not the code. We start by reading where your tech, team and roadmap actually are, set the technical direction, and oversee delivery for as long as you need it — then step back to advisory. From £3,000 a month.

Read the ground

Before any decisions, an honest look at what you've got — the architecture, the team, the roadmap, the vendors and the risks. Reported board-ready, so everyone's working from the same picture.
Set direction

Then the calls a full-time CTO would own: architecture, build-vs-buy, which vendors to challenge, and a plan that ties technology to the business. The most valuable decision is often a build stopped or a purchase avoided.
Oversee delivery

When you need hands on the wheel, the hands-on tier runs it — your developers and vendors managed a few days a month, hiring and technical vetting done, security and delivery risk reviewed as standing items.
Step back

Once things are stable you stop paying for intensity you no longer need — we step down to an advisory cadence, on call for the big decisions, rolling monthly with no long lock-in.

The decisions behind the builds

Leadership is what good projects look like before the code exists: choosing native iPad so NicheCom's app could drive laser measures, architecting a snagging platform for thousands of defects on live sites, and shaping a market-prediction platform into something the client's team could act on. Those calls are the job.

NicheCom

NicheCom, which produces floorplans at scale for estate agents, partnered with CodeLeap to prototype a purpose-built iPad app for their field surveyors.

WeSnag

A large London-based construction company managing major residential sites — dozens of contractors, thousands of defects — came to CodeLeap for a digital snagging platform. Within 6 months, we delivered a fully functioning mobile app that reduced human errors and accelerated the snagging process for construction managers.

Market prediction platform

We built a machine-learning platform for a financial analysis firm — supervised models that read the trend patterns and oscillators their analyst used to label by hand, a daily pipeline that writes the results into their working spreadsheet, and predictions served through an API.

The ground we cover

A CTO's judgement is only as good as the stacks it's been tested on — here's where ours comes from, shipped-with and works-with kept honest.

AWS & Google Cloud

Infrastructure decisions come from clouds we actually run — your hosting bill reviewed by someone who pays similar ones.
Django, React & React Native

Architecture calls are grounded in stacks we've shipped — which is why the advice includes what each choice costs in year three.
Azure & Microsoft estates

We work with Azure and Microsoft-centred estates — and a CTO whose first advice is 'replatform everything' should worry you.
Salesforce & your vendors

Vendor and quote review covers the Salesforce, ERP and agency contracts you already hold — we integrate with them and resell none of them, so the advice carries no commission.
Security & compliance

Security review is a standing agenda item, not a crisis response — access, backups and data handling checked against where you actually are.
Build-vs-buy

The most valuable technical decision is usually a purchase avoided or a build stopped — we've made those calls fifty times.
And much more

This is what comes up most often, not a limit. Bring us something that isn't on this list and we'll get up to speed on it — working with something new is the job, not an obstacle.

What our clients are saying

Real reviews from clients we have delivered for, on Clutch and elsewhere.

4.9 via Clutch

The enthusiasm, understanding of our mission, and passion from the first few minutes of the call were the deciding factors in choosing CodeLeap. Within 3 months of our app launching, we had over 1,500 downloads, appeared in leading publications from Forbes, The Metro, Marie Claire, Women's Fitness and many more, and started raising further investment.

Charlie CEO, Becon
They are incredibly diligent in the quality of work they produce, and go above and beyond when it comes to solving issues faced within the project, and to ensure we meet strict project deadlines. You never feel like you are one of many clients, and they ensure they are always there to help with any need you have, no matter how big or small.

Amelia Parmiter Marketing Manager, AWS - Marble
CodeLeap made me feel like my options were limitless in terms of what could be achieved, which was critical to me as we were creating something very unique. I'm glad I chose Codeleap over a large corporation as the personable approach resulted in a smooth and pleasant experience.

James CEO, Bearable
Working with CodeLeap was a very good experience from both a professional and personal point of view. These people know what they are doing and are both efficient and clever and made a good partner. I wouldn't hesitate to recommend CodeLeap.

John CEO, Neurometrics-Diab
CodeLeap adds so much value and goes above and beyond what I expected. CodeLeap's team is very flexible with all the different requests we've put in front of them. They've also been great with the whole business side of things, and being able to forecast for this industry is really helpful. Overall, I'm completely satisfied with their work — they've been incredibly helpful.

Johanne CEO, Cherry
Their flexibility and focus on quality were outstanding.

Mike Fenna CTO, Kite Insights
Marcelo has been wonderful throughout the process and we are very happy.

Amrit Director, Energy Company
