Fractional v.s Interim v.s Part-time

I have extensive experience in various Chief Technology Officer (CTO) roles, each with its unique responsibilities and benefits. In this article, I'll demystify the differences between a Fractional, Interim, and Part-Time CTO.

Fractional CTO

A Fractional CTO is ideal for businesses that need strategic technology leadership but not on a full-time basis. In this role, I work with multiple companies, dedicating a portion of my time to each. This arrangement provides businesses with high-level tech guidance without the commitment or cost of a full-time executive.

Interim CTO

As an Interim CTO, I step into the role during a period of transition or to fill a temporary vacancy. This might be due to the previous CTO leaving or during a period of significant change like a merger. My goal in these scenarios is to maintain continuity, provide leadership, and prepare the organisation for the next full-time CTO.

Part-Time CTO

In a Part-Time CTO role, I work with a company for a limited number of hours per week or month. Unlike a Fractional CTO, a Part-Time CTO typically dedicates their professional efforts to one organisation at a time. This role suits businesses that need ongoing, dedicated technical leadership but not to the extent of a full-time position.


Each role serves a distinct need. Fractional CTOs offer breadth and diverse experience, beneficial for growth and strategy across multiple sectors. Interim CTOs provide stability and leadership in periods of change. Part-Time CTOs offer a balance of consistent involvement and flexibility. I tailor my approach to fit the unique needs of each business, ensuring that they receive the right level of tech leadership to drive success.
