A fractional CTO is an experienced technology leader who works with your company part time. They take real ownership of technology strategy and decisions, without the cost and commitment of a full-time executive hire.
What a fractional CTO does
- Sets the technology strategy so it supports your business goals
- Makes key decisions on architecture, platforms, tools and vendors
- Builds the team: defines roles, interviews engineers and sets up ways of working
- Improves delivery: introduces practices like code review, testing and reliable releases
- Supports fundraising: prepares technical due diligence and a credible roadmap for investors
- Manages risk: security, scalability and technical debt
Signs you need one
- You're a non-technical founder building a software product
- Your engineering team is growing, but nobody owns the big technical decisions
- Releases are slow, quality is slipping or the team seems stuck
- You're preparing for a funding round or an acquisition
- Your CTO has left and you need leadership while you hire
How engagements usually work
Fractional CTO work is flexible. Common formats include a set number of days per month, regular strategy sessions with ad-hoc support, or a short, intensive engagement such as a technical audit or roadmap sprint. Interim CTO engagements cover a leadership gap full time for a limited period.
What it costs
Cost depends on the time commitment, the scope and the seniority you need. Because you only pay for the time you use, a fractional CTO is usually a fraction of the cost of a full-time executive with salary, benefits and equity. The best way to get a figure is to agree the scope first, then the time it needs.
Getting the most value
- Be clear about goals: what should be different in three or six months?
- Give real ownership: a fractional CTO is most useful when they can make decisions, not only advise
- Plan the next step: many companies use a fractional CTO to prepare for hiring a permanent one
