What is an interim CTO?
A plain answer: full-time technology leadership, temporarily. How the role works, what it costs, and how to tell it from a fractional CTO. Written by someone who has covered the seat.
A full-time CTO, for a while.
An interim CTO is an experienced Chief Technology Officer who takes over your technology function full-time, but temporarily. The seat is empty, or about to be, and someone senior has to run engineering every day: keep delivery moving, steady the team, and make the calls that can't wait for a six-month executive search.
The engagement has a built-in ending. An interim CTO stabilizes the function, leads it through the gap or the transition, then helps define and hire the permanent CTO and hands off cleanly. Done well, the permanent hire inherits a stronger org than the one the last CTO left behind.
I've done this work across the 30+ companies I've served since 2018, and because interim work is usually urgent, I can typically start within one to two weeks. Most of it is remote-first: I serve US companies from Eastern Time, with same-day overlap across every US time zone.
Also known as: temporary CTO, short-term CTO, transition CTO, acting CTO.
Interim vs fractional.
Both are hands-on and accountable. The difference is how much time, and for how long.
Part-time, ongoing
- , Leads your technology a day or two a week
- , An ongoing relationship that scales with the need
- , Best when you need senior judgment, not daily coverage
- , $10K–$18K a month on my published ladder
Full-time, temporary
- →In the seat every day, for a defined stretch
- →Covers a sudden gap or carries a transition
- →Ends with a clean handoff to the permanent hire
- →$30K a month embedded, on the same ladder
The interim CTO, explained.
What is an interim CTO?
An interim CTO is an experienced Chief Technology Officer who runs your technology function full-time for a temporary period, covering a sudden leadership gap or carrying the company through a transition. The role ends deliberately: the interim CTO stabilizes delivery, leads the team day to day, then hands off cleanly to the permanent hire.
How is an interim CTO different from a fractional CTO?
An interim CTO is full-time but temporary, in the seat every day to cover a gap or carry a transition until the permanent hire lands. A fractional CTO is ongoing but part-time, leading your technology a day or two a week alongside other commitments. Both are hands-on; the difference is how much time, and for how long.
Is a temporary CTO the same as an interim CTO?
Yes. Temporary CTO, short-term CTO, transition CTO and acting CTO are all the same job under different names: a full-time Chief Technology Officer engaged for a defined stretch rather than permanently. The distinction that actually matters is interim (full-time, temporary) versus fractional (part-time, ongoing).
How long does an interim CTO engagement last?
Until the transition is complete and the function is stable, sometimes a few months, sometimes longer. It ends when the problem is solved and the permanent hire is in place, not on an arbitrary date, and it ends with a documented, deliberate handoff rather than a cliff.
How much does an interim CTO cost?
In the US market, roughly $1,500–$2,500 a day, which lands at $25,000–$50,000 a month near-full-time. My published price is $30,000 a month for embedded, near-full-time leadership in the seat, working directly with me rather than through a firm. The full breakdown is in my interim CTO cost guide.
Will you help hire the permanent CTO?
Yes. Leaving cleanly is part of the job: helping define the role, assessing candidates, and handing off the architecture, decisions and plan so the permanent hire succeeds. An interim CTO who makes himself permanent by stealth isn't doing interim work.
How fast can an interim CTO start?
Fast, because the situation usually demands it. I can typically start within one to two weeks, against the three to six months a permanent executive search takes. That speed is most of the point: the team, the roadmap and the investors need a steady hand this week.
When should a company hire an interim CTO instead of rushing a permanent hire?
When the seat is empty and waiting isn't an option. A rushed executive search still takes months and a mis-hire at the CTO level costs a year, often the roadmap with it. An interim CTO covers the seat immediately and buys you the time to run the permanent search properly.
