Key takeaways
- The CTO owns product technology and engineering; the CIO owns internal systems.
- A VP of engineering runs delivery and the team, often reporting to the CTO.
- At a startup the CTO may approve almost every technical purchase; in a large firm, far fewer.
- Security, integration and data handling are the first things a CTO asks a seller about.
What are a CTO's responsibilities
A CTO's responsibilities are setting technical direction and making sure the company can build and run what it sells. As the company grows, the weight moves from writing code to setting strategy.
- Choose the architecture, languages and core platforms
- Build and lead the engineering organisation
- Own security, reliability and technical risk
- Decide whether to build, buy or partner for major components
- Explain technical trade-offs to the executive team and the board
CTO vs CIO
A CTO faces the product and its customers; a CIO faces the business and its staff. In a technology company the CTO is usually the senior technical leader, while in a bank, retailer or manufacturer the CIO often carries more weight.
The CIO runs internal IT: devices, identity, business applications, networks and the vendors behind them. The CTO runs the technology inside what the company sells. When a tool will be used by staff across departments, expect the CIO or IT team to lead the evaluation; when it becomes part of the product or the engineering workflow, expect the CTO.
How is a CTO different from a VP of engineering
A CTO decides which technology the company should bet on; a VP of engineering makes sure the team delivers. Many growing companies split the two once engineering has several managers.
The VP of engineering owns hiring plans, delivery dates, process and team health. The CTO keeps the long view: architecture, technical debt, new platforms and security posture. At a small startup one person, often a technical founder, holds both jobs.
How much of a technology purchase does a CTO decide
How much a CTO decides depends on the stage of the company. At a startup the CTO may choose and approve nearly every technical tool; in a large enterprise they set standards and leave most buying to teams, IT and procurement.
- Early startup: the CTO, often a founder, evaluates and signs for developer tools and infrastructure personally.
- Growing company: engineering managers propose tools, and the CTO approves anything that touches architecture, data or security.
- Large enterprise: architecture boards, security review and procurement handle most purchases, with the CTO involved in strategic platforms.
What should you prepare when selling to a CTO
Prepare clear answers on security, data handling, integration and the effort of running your product, because those are what a CTO checks first. Claims without technical detail lose their attention quickly.
Have documentation ready: how data is stored and separated, which certifications are held and which are pending, the access model, the APIs, and what happens to data when a contract ends. When a CTO asks for depth, offer a session with an engineer rather than another sales demo.

Common questions
Who does a CTO report to?
Usually the chief executive. In some companies the CTO reports to a chief operating officer or, inside a larger group, to a group technology leader.
Does every company need a CTO?
No. Companies that do not build technology products often have a CIO or head of IT instead. Software companies almost always have a CTO or a technical founder in that seat.
Is a CTO a technical role or a business role?
Both. Early on the CTO is often the strongest engineer; later the role is mostly strategy, hiring and explaining technical choices to the rest of the leadership.
