CTO

A CTO (Chief Technology Officer) is the person responsible for a company's technology strategy and execution. They make decisions about which technologies to use, how to build and scale technical systems, and how to align technology investments with business goals.

In a startup or small business, the CTO role is broad. They might be writing code, evaluating vendors, hiring developers, setting security policies, and presenting to investors — all in the same week. In larger companies, the CTO focuses more on strategy and leadership, with teams of engineers handling the implementation.

What a CTO actually does

• Technology strategy: Deciding what to build, what to buy, and what to outsource.
• Architecture decisions: Choosing the right technical foundations so systems can scale as the business grows.
• Team leadership: Hiring, managing, and mentoring the development team.
• Vendor management: Evaluating and negotiating with technology suppliers and platforms.
• Risk management: Ensuring systems are secure, compliant, and resilient.
• Stakeholder communication: Translating technical concepts for non-technical founders, investors, and board members.

Do you need a CTO?

Not every business needs a full-time CTO. If technology is central to your product or service, having strong technical leadership is essential — but it doesn't have to be a full-time hire from day one.

Many startups and SMEs work with a fractional CTO: an experienced technology leader who works with you part-time (typically a few days a month). This gives you senior-level guidance at a fraction of the cost of a full-time hire.

A fractional CTO is particularly valuable when you're:

• Building your first product and need to make foundational technology decisions.
• Managing an outsourced development team and need someone to oversee quality.
• Planning a fundraising round where investors will scrutinise your technology approach.
• Scaling and need to transition from "scrappy startup" to "reliable platform."
