FAQ

What should you know before hiring a fractional CTO?

What does a fractional CTO do?

A fractional CTO owns your technology function part-time: architecture, engineering team direction, infrastructure and delivery. For an AI-first company that includes which models and vendors to use, what to build versus buy, and how a prototype becomes a system that runs in production. You get CTO-level decisions without a full-time C-suite seat.

Fractional CTO or fractional CAIO?

A fractional CTO owns the whole technology function. A fractional CAIO owns the AI agenda specifically: where AI creates value, model and vendor strategy, governance. If technology leadership overall is the gap, start with a CTO. If engineering is healthy but AI decisions are ad hoc, start with a CAIO. For AI-first startups one fractional executive often covers both.
