Fractional CTO
What does a fractional CTO do?
A fractional CTO sets technology strategy against the business plan, decides architecture, makes delivery commitments verifiable, holds suppliers and agencies to what they promised, owns security and technical risk, and hires and develops the technical team. The work is judgement and accountability rather than writing code, and it is reported to the board in terms the board can act on.
The recurring work
Across engagements, the same six things account for most of the value.
- A written view of where technology, team, spend and risk stand today, with nothing softened.
- A technology plan that follows the business plan, with sequence and cost named.
- Delivery discipline, so a commitment made to the board can be checked against what shipped.
- Supplier and agency oversight, reading what was promised against what was delivered and invoiced.
- Security, resilience and technical due diligence readiness, before an investor or enterprise customer asks.
- Hiring, structure and coaching, including running the search for the permanent CTO who eventually replaces the arrangement.
What a good engagement leaves behind
A fractional arrangement done properly is temporary by design. It should leave written decisions, a plan the board can verify, stronger technical leads inside the business, and a company that can hold its next supplier to account without help.
How the time is usually structured
Commonly a fixed number of days a month, a standing slot with the founder or chief executive, attendance at the board or leadership meeting, and availability between those points for decisions that cannot wait. Engagements here are remote-first, with on-site time costed per engagement.
