Fractional CTO

#What is a fractional CTO and how is it different from hiring a full-time CTO?

A fractional CTO provides executive-level technology leadership on a part-time basis, typically 1-3 days per week. You get the strategic guidance, architectural oversight, and leadership experience of a senior CTO without the commitment and cost of a full-time hire. This model is ideal for growth-stage businesses that need CTO-level expertise but don't yet require or can't afford a permanent executive.

#What is a fractional CTO?

A fractional chief technology officer (CTO) is a senior technology leader who works with your business on a part-time or project basis, rather than as a full-time employee. You get the same strategic guidance, architectural oversight, and team leadership that a full-time CTO provides — but scaled to match your current needs and budget.

This model is particularly suited to growing businesses that need executive-level technology leadership but aren't ready for (or don't need) a full-time hire. A fractional CTO typically works 1-3 days per week, focusing on the highest-impact decisions: technology strategy, architecture reviews, team mentorship, and de-risking critical projects.

For a detailed comparison of costs and benefits, see the Fractional CTO Cost Guide for UK Businesses or read CTO Hiring vs Fractional: Which Is Right for Your Business?.

#When should a growing business hire a fractional CTO?

Consider a fractional CTO when you're facing major technology decisions (architecture choices, vendor selection, technical team building), experiencing repeated delivery issues, or preparing for significant growth. Common triggers include securing funding, planning digital transformation, or when your technical founder needs to focus on other aspects of the business. If technology is critical to your success but not your core expertise, a fractional CTO provides the trusted leadership you need.

#What is the difference between a fractional CTO and an interim CTO?

A fractional CTO and an interim CTO both provide senior technology leadership, but they serve different purposes:

Fractional CTO: Works with your business on an ongoing, part-time basis (typically 1-3 days per week). The engagement is designed to be sustained — providing continuous strategic guidance, architecture oversight, and team development over months or years. A fractional chief technology officer is the right choice when you need permanent senior tech leadership but don't need (or can't justify) a full-time hire.

Interim CTO: Fills a temporary full-time gap — typically when a CTO has left and you need someone to hold the fort while you recruit a replacement. Interim engagements are usually full-time but short-term (3-6 months).

The key difference is intent: fractional is a deliberate, long-term operating model; interim is a stopgap. Many businesses start with a fractional engagement and find it's all they need. For more on how this works in practice, see the CTO Hiring vs Fractional Comparison.

#Will a fractional CTO actually understand our business and industry?

Yes. A professional fractional CTO takes time to understand your business model, competitive landscape, and industry constraints. My approach includes discovery sessions with key stakeholders, review of existing systems and documentation, and ongoing engagement with your team. With over a decade of CTO experience across multiple sectors, I bring both deep technical expertise and the ability to quickly grasp domain-specific challenges.

#How much does a fractional CTO cost in the UK?

Fractional CTO costs in the UK typically range from £750 to £1,250 per day, depending on the intensity of the engagement, company stage, and duration. For a business engaging a fractional chief technology officer 1-2 days per week, monthly costs typically fall between £3,000 and £10,000.

This compares favourably to a full-time CTO hire, where total employment costs (salary, benefits, equity, recruitment fees) typically range from £150,000 to £250,000+ per year. A fractional model gives you equivalent strategic impact at 30-50% of the cost.

For a detailed breakdown with realistic scenarios by company stage, see the Fractional CTO Cost Guide for UK Businesses. You can also use our interactive cost calculator to estimate costs for your specific situation.

#How does a fractional CTO work with our existing technical team?

A fractional CTO complements your existing team by providing strategic direction, architectural oversight, and senior leadership without replacing your developers or technical leads. I work collaboratively, empowering your team through clear decision-making frameworks, technical mentoring, and removing roadblocks. My role is to elevate your team's capabilities, not micromanage their work. Many clients find their teams become more effective and confident with consistent CTO-level guidance.

#Do I need a CTO, or a Head of Technology or Technical Director?

Often the title is the last thing to settle. A CTO in the conventional sense is right when you need strategic direction, board communication, and someone accountable for the technology plan. If the gap sits closer to delivery, a Head of Technology shape works better: more time in the architecture and the code review queue, less in the boardroom. A Technical Director shape suits a business that needs depth on one system rather than breadth across all of them. And if you already have a capable technical lead, what you may actually want is a peer for them to pressure-test the big calls with.

I work across all four, and the engagement is priced the same way regardless. We can agree the shape in the discovery call, and change it as your business does.

#What results can we expect from engaging a fractional CTO?

Clients typically see clearer technology strategy and roadmaps, reduced project risk and delivery issues, better architectural decisions, and improved team confidence. Specific outcomes include faster, more reliable delivery (I compressed a 3-month discovery phase to 1 week using AI-augmented practices), authorisation services built from scratch with robust security, and board-ready technology communication. You gain the strategic clarity and technical leadership needed to scale your business without expensive missteps.

#What are your rates?

I work on a day rate of £800-1,000 per day for fractional CTO engagements, typically 1-3 days per week on retainer arrangements of 6 months or more. This model gives you senior strategic technology leadership without the commitment and cost of a full-time hire. Contact me to discuss your specific needs.

#What size of business is this suitable for?

It works across a range of business sizes and stages. Startups with non-technical founders benefit from experienced guidance through technical complexity. Growing SMEs often need senior oversight as they scale past what their current team can manage. Larger organisations engage when they need specific expertise, or an independent perspective their existing leadership doesn't have. The common thread is a technology leadership gap that doesn't justify a full-time executive hire, or can't wait for one.

#How does the engagement typically work?

Engagements are tailored to your situation. Some clients need ongoing retained support, a set number of days per month giving continuous strategic oversight. Others need an intensive project-based engagement to address one specific problem. Some start with an assessment phase to diagnose the real issues before defining the ongoing relationship. Most settle at 1 to 3 days a week on a retainer of six months or more. I'll talk your situation through with you and design an engagement model that fits your needs and budget.

#Can this help if we already have technical leadership but they're struggling?

Yes. Existing technical leaders are often stretched too thin, missing one specific piece of expertise, or just working through a hard period without support. A fractional CTO engagement can complement your existing team rather than replace it: mentoring, extra capacity for strategic thinking, or specialist guidance on architecture, AI adoption, or scaling practices. Some of the most useful engagements I've run have been peer support for a competent lead who had nobody to argue with.

#What industries do you work with?

Technology leadership challenges are remarkably consistent across industries. I've worked with PropTech platforms, logistics companies, legal services, healthcare organisations, NGOs, and various SaaS businesses. The technical patterns - scaling, modernisation, team development, delivery improvement - translate across sectors. What matters is understanding your specific business context and adapting the technical approach accordingly.

#How is this different from a traditional technology consultancy?

Traditional consultancies often deliver reports and recommendations, then leave you to implement them. A fractional CTO engagement is hands-on and accountable. I work alongside your team, make the decisions with you, and stay engaged through execution. That comes from someone who has built and shipped real systems rather than only advised on them.

Project Delivery & Rescue

#What is project delivery and rescue, and when do I need it?

Project delivery and rescue provides senior technical leadership to guide your team through complex builds or recover failing projects. You need it when projects are behind schedule or over budget, your team lacks senior architectural guidance, AI-generated code has created production issues, or you're starting a complex build that needs experienced leadership. This service combines technical leadership with architectural oversight, ensuring your team has the guidance they need to get projects back on track or start on solid foundations.

#How is your approach different from traditional project management?

I provide engaged technical leadership, not just scheduling and reporting. This means reviewing architecture, making technical decisions, mentoring your team, and contributing to implementation when it adds value. Traditional project managers track progress but can't solve technical blockers or validate architectural approaches. My CTO and architect background means I understand the technical work deeply, can course-correct technical decisions, and deliver working systems, not just status reports.

#Can you rescue a project that's already failing?

Yes. Project rescue engagements typically start with rapid assessment (2-3 days) to identify root causes, stabilise immediate issues, and create a recovery roadmap. Common rescue scenarios include architectural problems causing performance issues, unclear requirements creating scope creep, technical debt preventing progress, or team skill gaps blocking delivery. I've successfully rescued projects by rebuilding core systems (risk engine in 3 days), introducing proper architecture patterns, and bringing clarity to chaotic situations.

#Do you work with our existing team or replace them?

I work with your existing team, not replace them. My role is to provide the senior leadership, technical direction, and architectural capability your team needs to succeed. Many project failures aren't due to bad developers but lack of clear technical leadership and architectural guidance. I empower your team through mentoring, clear decision-making, and removing technical blockers. Most clients find their teams become more effective and confident with consistent senior guidance.

#What engagement models do you offer for project delivery?

I offer flexible models including dedicated project engagement (full-time or near full-time for project duration) and fractional engagement (2-3 days per week for longer projects). Engagements can be time-and-materials or fixed-scope depending on project clarity. For project rescue, I typically start with a rapid assessment before committing to a full recovery engagement, ensuring I understand the situation before proposing solutions.

#How is project work priced?

Project delivery and rescue work can be structured as fixed-scope projects or time-and-materials engagements, depending on project clarity. For well-defined work, I provide fixed-scope pricing focused on outcomes. For exploratory or rescue work where the full scope isn't clear, I work at my standard day rate (£800-1,000/day) with regular check-ins to ensure we're delivering value.

Project rescue typically starts with a paid rapid assessment (2-3 days, £2,400-3,000) that provides root cause analysis and a recovery roadmap with no obligation to proceed to full engagement. You get actionable insights whether or not we continue working together. Contact me for a project review to discuss the right approach for your situation.

#What if you assess my project and determine it can't be rescued?

I provide honest assessment even when it's difficult to hear. If rescue isn't viable or cost-effective, I'll explain why and recommend alternatives: managed project sunset, rebuild with salvaged components, or alternative approaches. You're paying for honest expertise and realistic options, not false hope. Most projects can be rescued with the right approach, but I won't take your money for a doomed effort. The rapid assessment exists precisely to answer this question before you commit significant resources.

#Why not just hire a senior developer or project manager instead?

Hiring takes 3-6 months (recruitment, onboarding, ramp-up) and costs £80-120k/year plus benefits. By the time they're productive, your troubled project may have failed. Project delivery and rescue engagements provide immediate senior capability - I can start assessing your project within days and guiding solutions within weeks.

What makes this different: I have experience as both a senior developer and a project manager, so I can bridge technical and management perspectives. For projects with defined endpoints, a time-boxed engagement is faster and more cost-effective than permanent hiring.

#Can you help us engage additional development resources?

Yes. If your project needs more development capacity than your team can provide, I can help you evaluate and engage the right resources. This might mean helping you assess agency partners, vet contract developers, or structure engagements with external teams. My role in these situations is to provide technical oversight: ensuring external resources understand the architecture, reviewing their work, and maintaining quality standards.

#How do you communicate progress to non-technical stakeholders?

I provide clear, jargon-free status updates focused on business outcomes: what's working, what's at risk, what decisions are needed, and realistic timelines. You'll always know where the project stands without needing to translate technical language. For rescue projects, I establish regular check-ins (typically weekly) with both technical and business stakeholders.

#What methodology do you use for project delivery?

I'm pragmatic about methodology - the right approach depends on your team, your organisation, and the project context. For rescue projects, I typically start with rapid assessment and stabilisation before introducing process improvements. For greenfield builds, I advocate for iterative delivery with clear milestones. During the initial assessment, I help you design an approach that works for your specific situation.

Technical Due Diligence

#What is technical due diligence and when is it needed?

Technical due diligence is an independent assessment of a technology platform, codebase, or technical team, typically performed before investment, acquisition, or major partnership decisions. You need it when evaluating a potential acquisition target, assessing technical risk before investment, validating vendor claims, or planning technology transitions. It provides objective analysis of technical quality, scalability, security, and risk to inform business decisions.

#How do you assess codebases and technical platforms?

I use a combination of AI-augmented analysis tools and hands-on expert review. Automated tools scan for code quality issues, security vulnerabilities, and architectural patterns across the entire codebase (I've analysed 390+ repositories in a single engagement). Senior review then focuses on architectural decisions, scalability concerns, technical debt severity, and team capability assessment. Reports are jargon-free and prioritised by business impact, not just technical severity.

#What does a technical due diligence report include?

Reports include an executive summary with risk rating, codebase quality assessment, technology stack evaluation, scalability and performance analysis, technical debt quantification, team capability assessment, and prioritised recommendations. Reports are written for business decision-makers, translating technical findings into commercial risk and opportunity language.

#How long does technical due diligence take?

Typical engagements range from 3-5 days for focused assessments to 10-15 days for comprehensive reviews, depending on the size of the ecosystem. AI-augmented analysis significantly accelerates codebase review. Most clients need results quickly for transaction timelines, so I structure engagements to deliver initial findings within the first week.

#What makes your approach to technical due diligence different?

I combine CTO-level strategic perspective with hands-on architect experience and AI-augmented analysis tools. This means faster, deeper assessment than traditional manual reviews, business-impact prioritisation rather than just technical checklists, and jargon-free reporting for non-technical stakeholders.

#What's the difference between M&A due diligence and investor due diligence?

M&A due diligence focuses on integration: Can we merge these systems? What will it cost? Are there deal-breakers that affect valuation? Investor due diligence focuses on growth potential: Can this technology scale 10x? Is there a defensible competitive moat? Can this team execute?

#When should I request a technical health check instead of transaction due diligence?

Technical health checks are for proactive assessment outside of transaction pressure. Common triggers include new CTO onboarding, pre-fundraising preparation, annual governance reviews, post-incident improvement planning, or technology roadmap validation. Health checks emphasise improvement roadmaps and ongoing advisory rather than go/no-go recommendations.

#What are common red flags you look for in technical due diligence?

Critical red flags include undisclosed security breaches or unpatched vulnerabilities, massive technical debt requiring complete rewrites, key person dependencies, IP ownership issues, compliance violations, and unrealistic roadmaps. I distinguish between deal-breakers and yellow flags that are manageable with proper planning.

#How is technical due diligence priced?

Technical due diligence is priced on a project basis following a scoping call. Every engagement starts with a free 30-minute discovery conversation. Based on this, I provide a fixed-price proposal covering the agreed scope and deliverables.

Legacy Modernisation

#What typically drives the need for legacy modernisation?

Two factors usually force the decision. First, accumulated technical debt: years of quick fixes make the system expensive to change. Second, end-of-life dependencies: vendors drop support for frameworks or platforms. Often both combine.

#What is legacy modernisation and how does it differ from a complete rewrite?

Legacy modernisation is a phased, incremental approach using patterns like the Strangler Pattern. Rewrite risks include 6-18 month development with limited features, high failure rate, and loss of undocumented business logic. Modernisation provides business continuity, incremental value delivery, and reduced risk.

#Do you do the migration work yourself, or does our team execute?

I focus on planning, architecture, and governance. Your team executes the implementation. I assess your ecosystem, design the migration strategy, and provide ongoing oversight.

#Can AI help with legacy modernisation?

Yes, significantly. AI-powered tools accelerate legacy system documentation, policy and standards documentation, and code analysis. I use AI/MCP agents to analyse codebases, extract business logic, and document undocumented systems.

#What are the typical risks of legacy modernisation and how do you mitigate them?

Common risks include data loss, functionality gaps, performance degradation, and losing critical business logic. I mitigate through comprehensive discovery, testing strategies, phased rollouts with rollback capability, and ongoing governance.

#How long does legacy modernisation typically take?

Assessment and planning takes 5-10 days. Implementation depends on complexity but typically spans 6-18 months. AI-augmented documentation accelerates the discovery phase.

#How do you manage scope creep during modernisation?

I establish clear scope boundaries during planning, distinguishing between 'like-for-like migration' and 'enhancement opportunities'. My governance role includes protecting scope and pushing back on mid-project expansions.

#What opportunities does modernisation create beyond just replacing the old system?

Common opportunities include architectural simplification, addressing scalability constraints, improving code quality, enabling new functionality, and reducing operational costs.

#Should we use Agile or traditional project management for modernisation?

I generally recommend a hybrid approach. Traditional planning for the overall roadmap, Agile practices for implementation within each phase.

#What if our internal team doesn't have the skills to execute the migration?

I assess capability during planning and design the roadmap accordingly. Options include upskilling your team, augmenting with contractors, or hands-on intervention for complex areas.

#How much does legacy modernisation typically cost?

Phase 1 (Assessment & Planning): £4,000-10,000 (5-10 days). Phase 2 (Governance): £3,200-8,000/month (1-2 days/week retainer). Implementation is your team's cost.

#How do we measure modernisation success?

Business metrics (reduced maintenance costs, increased velocity), technical metrics (test coverage, deployment frequency), and migration progress (% legacy retired, business logic documented).

#Should we migrate to microservices as part of modernisation?

It depends on your scale, team structure, and operational maturity. I assess whether microservices or a modular monolith pattern better fits your context.

#How do I know if our legacy system is actually a problem or just old?

A legacy system becomes a business problem when: change velocity slows, risk increases, costs escalate, talent gaps emerge, or compliance exposure grows. If you're experiencing 2+ of these, modernisation planning should start now.

#What technology platforms do you work with?

I've guided modernisations across .NET, Java, Ruby/Rails, PHP, and legacy JavaScript. My approach is platform-agnostic - migration patterns apply regardless of technology.

#I'm a non-technical founder. Is this service right for me?

Yes. I translate technical decisions into business outcomes, help you understand trade-offs, and ensure you're making informed choices. You don't need to be technical.

#What's the process if I want to explore this?

Free 30-minute consultation, then a scoping proposal for Phase 1 (Assessment & Planning), then Phase 2 (Governance & Oversight) if you proceed.

#How does the engagement and pricing work?

Phase 1 is fixed-scope (5-10 days at £800-1,000/day). Phase 2 is a flexible retainer (1-2 days/week). The retainer can flex up for critical situations.

Architecture Advisory

#What is architecture advisory and when do I need it?

Architecture advisory provides on-demand access to senior architectural expertise for critical technical decisions. You need it when planning major system changes, evaluating technology choices, or when your team needs peer-level validation.

#How is architecture advisory different from hiring a contractor or consultant?

Architecture advisory is peer-level guidance, not just implementation. You get strategic architectural advice, pattern recommendations, risk assessment, and validation from someone with over a decade of CTO and architect experience.

#Can you help us adopt AI-augmented development practices?

Yes. I provide practical, evidence-based guidance on AI adoption. My approach is grounded in real production experience and research-backed understanding of AI limitations.

#What architectural challenges do you typically help with?

Common challenges include microservices vs monolith decisions, legacy modernisation strategies, authorisation and security architecture, API design, and scaling strategies.

#How do architecture advisory engagements typically work?

Engagements can be project-based (5-10 days) or ongoing retainer. Both models complement your team's existing capabilities without creating dependencies.

#What are your rates?

I work on a day rate of £800-1,000 per day, structured as scoped project engagements or ongoing retainers.

AI-Augmented Development

#What does AI adoption consulting involve?

AI adoption consulting helps you integrate AI-augmented development practices into your team's workflow safely and effectively. Includes workshops, guidance, quality assurance frameworks, and hands-on coaching.

#How do you ensure AI-augmented work maintains quality standards?

I implement structured quality controls including human review gates, architectural oversight, test coverage requirements, and documentation of AI-assisted decisions.

#What results have you achieved with AI-augmented development?

Real client outcomes include compressing a 3-month discovery phase to 1 week (BPP/BuildCircle), building a risk assessment engine in 3 days (Evently), and reducing research work from months to hours.

#Will AI adoption require significant changes to our existing workflow?

Not necessarily. I take an incremental approach that integrates with your current practices. Initial adoption typically starts with documentation and research tasks, then expands.

#Is AI adoption suitable for regulated or high-compliance industries?

Yes, with appropriate controls. I help establish compliance-aware practices that leverage AI for efficiency while maintaining audit trails, security standards, and regulatory requirements.

#What are your rates?

I work on a day rate of £800-1,000 per day, structured as scoped project engagements or ongoing retainer arrangements.

Industries

#Do you only work with companies in these specific industries?

No - these are industries where we have deep, proven expertise. We work across many sectors and can bring our technical leadership skills to any domain. If your industry isn't listed, we'd love to discuss your specific challenges.

#How do you develop expertise in new industry sectors?

Our approach combines rapid domain immersion with proven technical patterns. We invest time upfront understanding your regulatory environment, workflows, and competitive landscape. This foundation, combined with our engineering expertise, means we deliver value quickly without the learning curve typical of generalist consultancies.

#Can you work on projects that span multiple industries?

Absolutely. Many of our most successful engagements involve cross-industry expertise - for example, applying PropTech transaction workflows to Insurance claims processing, or bringing Financial Services compliance patterns to Healthcare platforms.

#What makes your industry expertise different from other consultancies?

We don't just study industries - we've built production systems within them. Our team has hands-on experience with FCA compliance, PDTF integrations, defence-grade security, and healthcare data governance. This practical knowledge accelerates delivery and reduces project risk.

Pricing

#Do you charge a day rate or a retainer?

Both, depending on the engagement. Day rates are £800 to £1,000. Most ongoing work runs as a retainer, a set number of days per month over six months or more, which gives you a predictable monthly cost and gives me enough continuity to be useful rather than perpetually catching up. Shorter project-based pieces are quoted on days. There's no discovery fee either way.

General questions

#How do I get started?

Book a discovery call to discuss your situation. There's no obligation. It's a conversation to understand your challenges, work out whether we're a good fit, and talk through possible approaches. If it makes sense to proceed, we'll scope an engagement that matches your needs and budget.
