What is a fractional CTO?
Short answer
Fractional leadership provides ongoing technology leadership on a part-time basis. Scope and involvement are agreed around the organisation’s needs. The remit can include technology strategy, engineering leadership and representing technology to the board, with clear responsibility for decisions and outcomes agreed at the start.
What does a fractional CTO actually do?
The remit is agreed around the organisation’s needs. It can include:
- Setting technology strategy and a roadmap tied to commercial goals
- Hiring, structuring and managing the engineering team, including difficult staffing decisions
- Choosing architecture and engineering standards that suit the stage of the business
- Owning the engineering budget, including cloud and tooling spend
- Representing technology to the board, investors and enterprise customers
A good fractional CTO makes decisions and is accountable for them. If the arrangement is purely advisory, it is closer to a technical adviser.
How is it different from a technical adviser or consultant?
| Aspect | Fractional CTO | Adviser or consultant |
|---|---|---|
| Decision rights | Owns technology decisions | Recommends; you decide |
| Team | Leads and manages engineers | Usually no line management |
| Time | Ongoing, part-time involvement agreed around the remit | Involvement agreed around the advisory or project remit |
| Accountability | For delivery and outcomes | For the quality of advice |
When does a fractional CTO make sense?
- You have an engineering team, or are about to, but no senior technology leader
- You need CTO-level judgement but would not fill five days a week of it yet
- You are preparing for a funding round or enterprise sales and need credible technical leadership
- You want to test what a CTO role needs before hiring one full-time
