What is a fractional CTO, and does your business need one?

Most growing businesses reach a point where technology decisions are too important to leave to whoever is least busy, but not big enough to justify a full-time chief technology officer on a six-figure salary. A fractional CTO fills that gap. Here is what the role involves, when it makes sense and what to look for.

What a fractional CTO does

A fractional CTO is a senior technology leader who works with your business part time, typically a few days a month, on a retained basis. They do the job a full-time CTO would do, scaled to what you need:

• Set the technology direction. What systems you should have, in what order, and why.
• Choose systems and suppliers. Run selections properly, ask the questions a non-technical owner cannot, and avoid expensive mistakes.
• Manage developers and agencies. Translate business needs into requirements, review proposals and work, and hold suppliers to account.
• Own security and risk. Make sure backups exist, access is controlled, and data protection obligations are met. See our UK GDPR checklist.
• Plan investment. Build a roadmap and budget, so technology spend is deliberate rather than reactive.
• Sit at the leadership table. Bring the technology view to business decisions, and the business view to technology decisions.

What they are not

Not IT support. They do not fix printers or reset passwords; they make sure someone good does, and that the arrangement is right. Not a developer. They do not write the code, though they can review it and choose who does. Not a project manager, though they often oversee projects.

When it makes sense

• You are choosing or replacing a core system, such as an ERP, and want someone independent in the room.
• You have a developer or agency and nobody on your side who can judge their work.
• Technology is becoming central to how you compete, but not central enough for a full-time hire.
• You have had a bad experience with a project and want to avoid another.
• You are growing fast and the systems that got you here will not get you there.
• You are preparing for investment, sale or audit and need technology to stand up to scrutiny.

When it does not

If your technology needs are simple and stable, a good IT support company and an occasional consultant is enough. If technology is the product and you are building a software company, you need a full-time CTO or a technical co-founder, not a fractional one.

What it costs

A fixed monthly retainer for an agreed number of days, usually far less than a full-time senior hire once salary, national insurance, pension and benefits are counted, and with the flexibility to scale up or down. The return usually shows in one of two ways: a project that goes right instead of wrong, or a purchase that was avoided because it was not needed.

What to look for

• Breadth of experience across systems, suppliers and businesses of your size. Someone who has only ever run one type of system will recommend it.
• Independence. If they are tied to selling you a particular platform, they are a salesperson.
• Plain speaking. If you cannot understand them, they are not doing the job.
• References from businesses like yours.
• A clear arrangement: days per month, what is included, how it flexes, and how it ends.
