Most growing firms don't need a full-time CTO. They need someone senior in the room four to eight days a quarter — to translate business goals into a tech plan, sit with the board, and own the decisions nobody else is qualified to make.
Vendor pitches, architecture choices, hiring — all flowing to someone who shouldn't be deciding the depth of Kubernetes.
Smart juniors making big calls. No one mentoring or pushing back. Tech debt piling up.
Annual planning happens. Nobody owns the technology line.
Need someone senior to evaluate a target's stack in two weeks. Don't have that person.

“We were burning weeks on architecture debates. Our fractional CTO came in, listened for two weeks, then cut through it in one Friday session. Six months later, we'd shipped two of the three big initiatives. The CFO has tried to put him on the payroll twice.”
Sometimes, by mutual agreement. Most clients don't take that step — the fractional model is the destination, not a stopgap.
Hands deeper. Attends operating reviews, coaches engineering, owns the roadmap. A board advisor offers perspective; a fractional CTO drives execution.
No. We work with them — coach, partner, sometimes push back. The VP Engineering still runs the day-to-day team.
We swap. We have multiple senior advisors. Match is critical.
