What a fractional CIO for fintech actually does

A fractional CIO is an experienced chief information officer who works with your fintech on a part-time, ongoing basis, usually one to a few days a week, taking accountability for technology strategy, delivery, resilience and the governance that sits over all of it. In fintech this is not a generic IT role. The person needs to translate between your founders, your engineering leads, your board and the external parties who decide whether you can operate at all: the FCA, your sponsor bank, your acquirers and your enterprise customers. They own the question every fintech board eventually asks, which is whether the technology can be trusted to handle other people’s money safely and to keep handling it as you grow. Starkhorn delivers this through a blended fractional CIO and CISO model, because in regulated finance the technology and security agendas cannot be cleanly separated.

The pressures fintech puts on technology leadership

Fintech compresses problems that other sectors get to solve in sequence. You are building product at venture speed while operating inside a regulatory perimeter designed for incumbents. A consumer lending platform, a payments business and an embedded finance provider all carry the same underlying tension: move fast enough to win the market, but never so fast that you breach the rules that let you trade. The technology leader holds that line. They decide which controls are non-negotiable from day one, which can mature over the next two quarters, and which are theatre that slows you down without reducing real risk. Getting that judgement wrong in either direction is expensive. Over-engineer and you burn runway; under-engineer and you fail an audit, lose a banking partner or suffer a breach that ends customer trust overnight.

There is also the partner and investor lens. Sponsor banks run due diligence on your security and operational resilience before they let you near their rails. Enterprise clients send security questionnaires that assume a named accountable executive. Investors at Series A and beyond expect to see a credible technology operating model, not a heroic founder-engineer holding everything together. A fractional CIO gives you that named, senior accountability without committing to a salary your stage cannot yet justify, a point we cover honestly on our pricing page and in the CIO and CISO cost calculator.

Risk and regulation: the fintech specifics

Financial services technology lives under more obligation than almost any other commercial sector. FCA expectations on operational resilience require you to identify important business services, set impact tolerances and prove you can stay within them through disruption. Consumer Duty raises the bar on how technology shapes customer outcomes, not just how it processes transactions. If you handle card data you are inside PCI DSS scope. If you operate across the EU or serve EU customers you face DORA and, for some, the wider obligations we explain on our NIS2 compliance page. None of this is optional, and all of it lands on the technology and security function.

The cost of getting it wrong is well documented. The IBM Cost of a Data Breach Report 2025 puts the global average cost of a breach at USD 4.44 million, and financial services consistently sits above that average. UK regulators have shown they will act: the ICO fined British Airways £20 million in 2020 and Interserve £4.4 million in 2022 over security failings. A fractional CIO for fintech builds the controls, evidence and reporting that keep you defensible, drawing on the same disciplines we set out across our cyber security for financial services and cyber security consulting work.

What fintech genuinely needs from the role

Fintechs do not need a figurehead. They need someone who will make decisions and own the consequences. In practice that means a few things working together. It means a clear technology strategy that ties engineering investment to commercial milestones, the kind of IT strategy a board can actually read. It means a security posture that survives a sponsor bank’s due diligence and an enterprise buyer’s questionnaire, delivered through structured CISO as a service or a virtual CISO arrangement. And it means a plan for the day something goes wrong, because in payments and lending it eventually does. That is why a tested incident response plan and genuine ransomware readiness matter more here than almost anywhere else.

• Technology strategy aligned to your funding stage and product roadmap
• Security and resilience evidence that passes partner and regulator scrutiny
• Vendor and cloud architecture decisions that scale without locking you in
• Board reporting that turns technical risk into commercial language
• An incident response capability you have actually rehearsed

AI, governance and the board’s growing exposure

Fintechs are among the fastest adopters of AI, from credit decisioning to fraud detection to customer support. That speed creates a new class of risk that boards are only beginning to price in. Models that make lending or pricing decisions carry fairness, explainability and regulatory obligations. Tools adopted by teams without oversight create exposure that nobody owns. A fractional CIO puts structure around this through proper AI governance and by surfacing the shadow AI already running inside your business. They also strengthen the board’s own grip on technology risk, which is the heart of our board cyber governance and board IT strategy services. In a regulated firm the directors are accountable whether or not they understand the detail, so the technology leader’s job is partly to make sure they do.

How a fractional leader delivers without a permanent hire

A full-time fintech CIO or CISO is a significant fixed cost. UK CISO salaries run roughly £95,000 to £600,000 or more depending on scope and sector, before you add the recruitment cycle, equity and the risk of hiring the wrong person at the wrong stage. A fractional model gives you senior judgement at the cadence your business needs, scaling up around a funding round, a regulatory milestone or an acquisition, and scaling back once the work is embedded. It also brings pattern recognition: someone who has handled resilience, security and transformation across organisations rather than learning your sector for the first time on your payroll. Where the need is a defined gap rather than ongoing, an interim CIO engagement or focused technology due diligence can be the right shape instead. Many growth-stage fintechs run this as part of a broader mid-market digital transformation, and we set out the wider remit on our vCIO page and explain the role itself in what is a vCISO.

Why Starkhorn

Starkhorn is led by Daniel J. Jacobs, who has spent over 20 years in technology and security, 15 of them in leadership roles, including Interim Group Technology Director at VetPartners, the BC Partners-backed veterinary group, and CIO and CISO at Jardine Motors Group. He is the author of The Strategy Bridge and holds PRINCE2, ITIL Foundation and full membership of the Institute of Interim Management.

That combination of private-equity-backed scaling, board-level accountability and held CIO and CISO responsibility is exactly what a growth-stage fintech needs in a fractional technology leader: someone who has answered to investors, owned both the technology and the security mandate, and made resilience decisions where the consequences were real.
