WHY YOU WOULD NEED A FRACTIONAL CTO
The right Fractional CTO changes everything about how your technology performs.
A fractional CTO is a technical leader who works inside your business on a part-time or ongoing basis, taking full accountability for your technology without the cost of a full-time hire.
Most businesses hire a fractional CTO because they need technical leadership now but aren't ready to commit to a permanent CTO salary, or because the role has been vacant and the gap is starting to cost them.
Sam Halcrow has filled that role for 253 companies across infrastructure, SaaS, enterprise transformation, and early-stage startups. He leads every engagement personally and brings a 26-strong engineering team across software, AI, cloud, and security when the work needs one.

FAQ
Frequently asked questions
What are the signs my business needs a fractional CTO?
Common triggers: technical decisions are having consequences nobody in the room can properly evaluate, an engineering team lacks senior direction, a fundraise or technical due diligence is coming up, or the business has outgrown ad hoc technical decision-making but isn't ready for a full-time executive.
How is this different from hiring a full-time CTO?
A full-time CTO is one person dedicated entirely to your business, usually at $250k-$450k a year once everything is factored in. A fractional CTO gives you the same level of decision-making and accountability, but for a set number of days a month, at a fraction of the cost.
Is a fractional CTO different from an interim CTO?
Yes. An interim CTO is a temporary, usually full-time placement, brought in while a business searches for a permanent hire. A fractional CTO is an ongoing part-time arrangement that can run for years, not a stopgap.
What kinds of organisations do you typically work with?
Any organisation that is making significant technology decisions and needs someone senior enough to make them well. Some have engineering teams already, some don't. Some are mid-project, some are just starting. The common thread is they need a technical leader who's accountable for the outcome.
What happens if we already have an in-house engineering team or a vendor?
I work closely with them, setting direction and checking that decisions and delivery are sound. If you don't have an engineering team in place, I can bring my own team of engineers to fill that gap rather than leaving you to hire and manage one separately.
