The Gap Between IT Support and IT Strategy

Most growing businesses hit a point where their IT works but their technology decisions feel reactive. New tools get adopted without evaluation. Contracts auto-renew without negotiation. The IT budget is whatever last year’s was plus a bit more. Nobody is asking whether the technology stack actually supports where the business is heading.

That is the gap a fractional CTO fills. Not another pair of hands on the helpdesk, but a senior technologist who sits with your leadership team and makes sure technology decisions serve your business goals. Our managed IT support handles the operational layer while a fractional CTO provides the strategic direction.

What a Fractional CTO Actually Does

Our vCIO services start with understanding your business. Where are you now? Where are you heading in the next 12-24 months? What does your technology need to look like to get you there?

From that understanding, we build a technology roadmap. This is a practical, budgeted plan that sequences your IT investments over time. It might include a cloud migration in Q2, a security uplift in Q3, and a new CRM deployment in Q4. Each initiative has a business case, a timeline, and a cost estimate.

Between the big projects, your fractional CTO handles the ongoing strategic work that otherwise falls through the cracks. Vendor contracts coming up for renewal get reviewed and renegotiated. New software requests get evaluated against your architecture standards. The IT budget gets a proper annual planning cycle with quarterly reviews.

IT Strategy for Financial Services

For FCA-regulated firms, technology strategy is inseparable from compliance strategy. DORA requirements mean your technology resilience is now directly in scope for regulatory review. Your operational resilience framework needs to account for critical IT services, third-party dependencies, and recovery capabilities.

Our fractional CTOs have deep experience in financial services IT. We understand the regulatory landscape, the vendor ecosystem, and the specific challenges of running technology for hedge funds, PE firms, and wealth managers. We speak both the language of technology and the language of financial regulation.

M&A Technology Due Diligence

If your firm is acquiring or merging with another business, technology due diligence is essential. We assess the target’s infrastructure, contracts, security posture, technical debt, and integration complexity. We have reviewed dozens of acquisitions and know where the hidden costs and risks live — from legacy systems with no documentation to software licences that do not transfer.

The output is a clear report your deal team can use: what the technology is worth, what it will cost to integrate, and what risks you are taking on. Learn more about how we approach IT due diligence for private equity transactions.

How It Works

Engagements typically start at 2 days per month and adjust based on what your business needs. There is no long-term lock-in. We work alongside your existing IT team or managed service provider, filling the strategic layer that operational IT does not cover.

Strategy, Not Just Support

Managed IT keeps things running. A fractional CTO decides what should be running, what should change, and what you should invest in next. It is the difference between maintenance and progress.

Board-Ready Communication

We translate technology decisions into business language. Your board gets clear, jargon-free updates on risk, investment, and return — not a list of servers and tickets.

Fraction of the Cost

A full-time CTO in London costs £150,000-£250,000 plus equity. Our fractional CTO service delivers the same strategic thinking at a fraction of that, scaled to the time your business actually needs.

FAQ

Frequently asked questions

How much time does a fractional CTO spend with us?

It depends on your needs. Most clients start with 2-4 days per month, which includes a leadership meeting, vendor reviews, project oversight, and strategic planning. Engagements can scale up during periods of change like office moves, M&A, or major projects.

Is this different from your managed IT support?

Yes. Managed IT support handles day-to-day operations — helpdesk, monitoring, patching. Fractional CTO services are strategic: roadmap planning, budgeting, vendor management, and board reporting. Many clients use both, and they complement each other.

What kind of companies benefit most from this?

Businesses with 20-200 employees who have outgrown ad-hoc IT decision-making but are not large enough to justify a full-time CTO. We work with hedge funds, PE firms, law firms, consultancies, and [fast-growing startups](/industries/startups/).

Can your fractional CTO attend our board meetings?

Absolutely. We regularly attend board meetings and investor presentations to provide technology updates, risk assessments, and strategic recommendations. We present in business terms, not technical jargon.

What happens during M&A due diligence?

We assess the target company's technology stack, contracts, technical debt, security posture, and integration complexity. We provide a clear report with risks, costs, and a post-acquisition integration plan.
