Hiring a fractional CTO in fintech
In most sectors the technology function answers to the business. In a regulated firm it also answers, indirectly, to a supervisor who can ask what happens when it breaks and expects a documented answer. That is the difference, and it changes what the seat is for.
A fractional CTO in the UK charges £800 to £1,400 a day, which is £6,133 to £10,733 a month at two days a week. The bands for all eleven seats come off live listings on the bench and are published openly as data.
What is different about this seat in fintech
Operational resilience is a documented position, not an aspiration
A regulated firm is expected to know which of its services would cause intolerable harm if they stopped, how long it could tolerate them being down, and to have tested that it can stay inside that tolerance. That is a board-level statement with engineering consequences: it decides what gets redundancy, what gets a tested failover, and what is allowed to be a single point of failure. A CTO who has been through it starts with the service map, not the stack.
Third-party risk is your risk, and outsourcing does not move it
You can outsource the running of a thing and you cannot outsource responsibility for it. That means a register of who you depend on, what happens if one of them fails, exit plans for the critical ones, and contracts that give you audit and information rights. The common failure is a core dependency onboarded by an engineer on a credit card, with no contract anybody in compliance has read.
Data residency and transfer is an architecture decision made early and expensively changed late
Where personal data physically sits, which entity controls it, and the legal basis for moving it across borders are questions with concrete engineering answers: region choice, replication topology, which vendors are in the path. Retrofitting this after a customer's procurement team asks is the expensive version, and it is the common one.
The change process is evidence, not bureaucracy
In an unregulated startup, how code reaches production is an engineering preference. In a regulated one it is something you may have to demonstrate: who approved it, what testing happened, how it would be rolled back. The trick is a process that is genuinely light and genuinely recorded, because a heavy one gets bypassed and a bypassed one is worse than none.
What the seat owns here
- The service map, impact tolerances and the resilience testing behind them
- The third-party register, exit plans and the contracts that make them possible
- Data residency, transfer basis and the architecture that implements both
- A change process that produces evidence without slowing delivery to a crawl
- The technology section of an authorisation application, and the questions that follow it
What to ask a fractional CTO for fintech
- Which services here would cause intolerable harm if they stopped, and how long could we tolerate it?
- Show me a third-party register you have built. What was on it that surprised the business?
- Where does our personal data sit, and what is the basis for anything that crosses a border?
- How would you evidence a production change to a supervisor six months after it happened?
- What did you take out of a resilience test that you had assumed was fine?
Where it goes wrong
- Treating resilience as an infrastructure question when the tolerances are a board decision
- Onboarding a critical vendor with no contract, no exit plan and no owner
- Choosing a cloud region for latency and discovering later it was a data residency decision
- Building a change process so heavy that engineers route around it
When this is the wrong hire
If the product is not built and the firm is not authorised, the constraint is usually building the thing rather than governing it. A strong lead engineer will take you further than a fractional CTO until there is a system worth protecting and a supervisor to answer to.

Common questions
What does a fractional CTO cost in fintech?
The published UK band applies and regulated work sits at the upper end of it, because the combination of hands-on engineering judgement and regulatory fluency is genuinely uncommon.
Can a fractional CTO support an FCA authorisation application?
The technology and resilience sections, yes, and so can the follow-up questions, which is where applications usually slow down. The application itself is a regulatory piece of work and is normally led by a compliance specialist with the CTO supplying the substance.
Is a fractional CTO enough for a regulated firm, or do we need someone permanent?
It depends on whether the job is judgement or presence. Setting the architecture, the resilience position and the vendor governance is fractional work. Running an engineering team of twenty through daily incidents is not.
