Fractional CTOs and technology leaders in Australia

A fractional CTO is a senior technology leader who works with your business part-time. They set technical direction, make architecture decisions, and build or guide the engineering team.

Startups usually need one when a non-technical founder is making big technology calls, when an outsourced build needs senior oversight, or before technical due diligence for a raise.

There are three common ways to work with a fractional CTO. A fractional seat is an ongoing part-time role, usually a set number of days a week, where they own the function. A project is a defined piece of work with a clear finish line. Advisory is lighter touch, with regular check-ins to guide your team rather than doing the work.

Frequently asked questions

What does a fractional CTO do?

A fractional CTO owns technology strategy part-time. That can include architecture and platform decisions, hiring and leading engineers, managing development partners, security and preparing for technical due diligence.

How many days a week does a fractional CTO work?

It depends on the stage and the work. Many start with one or two days a week and adjust as needs change. Some work on a project basis with a fixed scope, and others advise with a regular check-in. Talk it through with the operator directly.

How is a fractional CTO different from a consultant?

A consultant usually delivers advice or a report and steps away. A fractional CTO works inside your business as part of the team, owns outcomes and is accountable for results over time, just on a part-time basis.
