Fractional CTO
Fractional CTO for businesses that need the work done, not the org chart.
Technology leadership without the £220k salary. We embed inside your existing team, audit the stack, identify the highest-impact systems to ship, and build them. No six-month onboarding. No equity. No full-time overhead.
01
What is a fractional CTO?
A fractional CTO is a senior technology leader who works with a business part-time or on an ongoing fractional basis instead of full-time. The fractional model exists because most SMEs between £500k and £5m revenue need serious technology leadership but cannot justify a £180k to £250k full-time hire with equity on top. A fractional CTO covers everything a full-time CTO does strategically: infrastructure decisions, technical debt, build-versus-buy choices, AI implementation, and the systems that move the qualified-inquiry number, but at 10 to 25 percent of the cost.
The useful ones do not arrive with a framework and a steering committee. They sit with the person who actually owns the booking calendar, the customer WhatsApp, the developer backlog. They watch what is costing the business three hours that should take five minutes. They make the technology call and ship the system inside that workflow within two to three weeks. Then they ship the next one.
Most fractional CTO engagements in 2026 fail for the same reason most AI consulting fails: the consultant arrives with a 60-page technical audit and a six-month roadmap. The roadmap goes into a Google Drive folder. Six months later the founder is still making every technology decision alone, the tech debt is worse, and the retainer has cost £30k for a document nobody opened.
We wrote up the full definition in our guide to what a fractional CTO is and a day-by-day breakdown of what a fractional CTO actually does. The short version: they own the technology layer of your business so you can own everything else.
02
Why most fractional CTO engagements fail
Read the r/startups threads from Q1 2026. The complaints land in the same three places every time.
“We hired a CTO for six months at £180k and the main deliverable was a technical strategy doc nobody read.”
“I don’t need someone to own the org chart. I need someone to fix our deployment pipeline before we launch.”
“Three SaaS tools for the same job because no one decided which one to use. Now we pay for all three.”
“Tech debt is eating us alive but we can’t afford the engineer who’d fix it.”
None of these founders needed more strategy. They needed someone to make a call and ship the fix. The fractional CTO market is full of consultants who produce deliverables that look like work but do not move the business. Audits without action. Roadmaps without releases. Technical recommendations sitting in a slide deck instead of running in production.
We wrote up the warning signs in our fractional CTO red flags guide and the seven signals that your tech is already holding back revenue in signs you need a fractional CTO.

How we approach it
Week one: audit, not onboarding theatre
Most fractional CTOs spend month one in onboarding. We spend week one auditing. We look at your stack, your costs, your development bottlenecks, and your highest-pain workflows. By the end of week one we have identified the three systems that would move your revenue number fastest and ranked them by build time. Week two we start building the first one.
We ship inside your existing stack, not on top of it
No new dashboards. No new tool to learn. We work inside the CRM, WhatsApp, email, booking system, and data infrastructure you already run. The systems we build run on what your team already knows, which means zero adoption friction and nothing to maintain in-house after we ship. Our fractional CTO services page details what each tier includes.
We make the call, then ship the outcome
The job of a fractional CTO is to take the technology decisions off your plate permanently, not to put more options on it. We evaluate the build-versus-buy question, pick the winning architecture, and ship it. Eight of our 12 clients moved their qualified-inquiry number 4x in 60 days. The two who did not had broken upstream tracking we had to fix before the AI layer had anything useful to work with.
We run the AI layer alongside the technology layer
AI-referred customers convert at 14.2 percent versus Google’s 2.8 percent. That is a 5x difference in conversion rate for the same customer acquisition cost. While we fix your operations and technology stack we also build the structured data, content infrastructure, and platform presence that gets you cited by ChatGPT, Perplexity, and Google AI Overviews. Our work as an AI strategy consultant sits inside the same fractional engagement.

What the numbers look like
A Dubai hospitality group with three venues had a development contractor costing £8,500 per month across three separate retainers. The contractor was delivering individual feature requests on each site without any shared infrastructure, so the same fix had to be built three times. We audited the stack in week one, migrated the common functionality to a shared layer in weeks two and three, and reduced the contractor cost by 60 percent. The three venue sites now deploy from a single pipeline.
A Manchester SaaS startup building a B2B scheduling tool had shipped four different versions of their core booking flow because they had no CTO and the founder kept changing the spec mid-sprint. We joined as fractional CTO, locked the architecture in week one, rebuilt the flow once correctly in weeks two to four, and the next sprint ran without a single architectural reversal. Time to market on new features dropped from six weeks average to nine days.
A Singapore logistics SME was paying for six SaaS tools that covered three overlapping jobs. No one had made the call about which to standardise on. We evaluated the overlap, recommended two tools to cut, negotiated the exits, and reduced the SaaS spend by £2,200 per month. The remaining tools were integrated via a shared data layer we built in three weeks. The operations team went from four manual data entry sessions per day to zero.
05
Fractional vs full-time: the actual numbers
A full-time CTO in 2026 costs £180k to £250k loaded. That is base salary plus national insurance, pension, benefits, recruitment fees averaging £25k to £40k, and equity that typically runs 0.5 to 2 percent for a senior technology hire. For a business doing £1m to £3m revenue, that is 15 to 25 percent of revenue going to one hire whose primary output in year one is meetings and a roadmap document.
A fractional CTO engagement at twohundred.ai runs £24k to £60k per year. No equity. No recruitment cost. No notice period. No benefit overhead. The scope is identical to what a full-time CTO delivers strategically: infrastructure decisions, system builds, technical direction, and the AI implementation layer. The difference is execution capacity on day-to-day engineering management, which most SMEs do not actually need until they have a team of five or more developers.
The full comparison is in fractional CTO vs full-time CTO, including the exact break-even point where a full-time hire makes more financial sense. It is later than most founders expect. We also cover how the fractional CTO role compares to a VP of Engineering, which is the other common hire at this stage.

Who this is for
Founders making technology decisions alone
You are the default CTO because you cannot afford to hire one. Every technology call lands on your desk. Every vendor pitch goes to you. Every outage wakes you up. This is the most expensive use of a founder's time in any SME.
Businesses with spiralling SaaS costs
79 percent of SMEs are paying for overlapping tools that nobody decided to rationalise. The average 12-person company pays for 23 subscriptions worth £3,000 to £5,000 per month. A fractional CTO audit finds the waste in week one.
Pre-raise startups that need technical credibility
Investors ask about your tech stack, scalability, security posture, and technical team. A fractional CTO can answer those questions, fix the gaps before the due diligence call, and sit in the investor meeting as the technical lead.
Scale-ups that outgrew their first tech hire
The developer who built version one is not always the right person to architect version three. A fractional CTO transitions the technology layer without firing anyone, structures the team for scale, and hands over cleanly when you are ready for a full-time hire.

Frequently asked questions
What does a fractional CTO actually do?
A fractional CTO is a senior technology leader who works with your business part-time or on a project basis instead of full-time. At twohundred.ai a fractional CTO engagement means the founder embeds inside your team, audits your existing technology stack, identifies the highest-impact places to ship working systems, and then builds them. The deliverable is not a roadmap. It is code running in production inside the tools your team already uses. Typical scope for a £2k-per-month Foundation engagement includes one working system shipped per quarter plus a monthly working session on technology direction.
How much does a fractional CTO cost?
We charge £2k per month for our Foundation tier, £3.5k for Growth, and £5k for Dominance. That is fixed monthly with no equity, no percentage of revenue, no hidden retainer fees. The market range for fractional CTOs in 2026 sits between £150 and £500 per hour, which works out to roughly £6k to £20k per month at serious engagement volume. A full-time CTO loaded with salary, national insurance, benefits, and equity costs £180k to £250k per year. Fractional is the same strategic oversight for roughly 10 to 25 percent of that number.
How is a fractional CTO different from a full-time CTO?
A full-time CTO owns the engineering org, manages the team, runs hiring, and sits in the leadership meeting every week. A fractional CTO does everything a CTO does strategically, owns the technology decisions, identifies what to build and in what order, and ships the systems themselves, but works across two or three clients simultaneously rather than inside one company full-time. For a £500k to £5m SME that cannot justify a £220k salary, a fractional CTO delivers the same outcome at a fraction of the cost. The trade-off is capacity: a fractional CTO cannot manage your engineering team day to day if you have one. They can hire it, structure it, and hand it off.
Do I need a fractional CTO or an AI consultant?
The question is what your biggest technology gap actually is. An AI consultant focuses specifically on building AI systems inside your existing stack: WhatsApp qualifiers, Gmail-side responders, CRM enrichment pipelines, booking automation. A fractional CTO covers the whole technology stack: infrastructure, security, team structure, technical debt, build-versus-buy decisions, and AI where it fits. If your problem is specifically AI systems and customer acquisition, an AI consultant is faster and cheaper. If your problem is the whole technology layer of the business, a fractional CTO is the right hire. At twohundred.ai the two roles sit in the same person, so the scope depends on what you need most.
When should a startup hire a fractional CTO?
The right time is when technology decisions are slowing down revenue and the founder is making them without confidence. Common signals: you have shipped three versions of the same feature because nobody decided the right architecture upfront, your developer costs keep growing but the product does not feel more stable, you are choosing between three SaaS tools for the same job because no one made the call, or you are about to raise a round and investors are asking questions about your technical infrastructure you cannot answer. A fractional CTO does not require a six-month onboarding ramp. First working session in week one, first architectural decision made in week two, first shipped system in week three.
What is included in the fractional CTO service?
Foundation tier at £2k per month includes a full technology audit in month one, one system shipped per quarter inside your existing stack, a monthly working session on technology direction, and standing availability on Telegram or Slack for urgent decisions. Growth at £3.5k per month adds two systems shipped per quarter, weekly working sessions, full ownership of the technology roadmap, and competitor technology tracking. Dominance at £5k per month is continuous shipping, embedded inside your team as the functional CTO, and is capped at three clients per quarter.
