Your technology partner, from idea to scale.

If your hardest open question is “how do we build this”, you need a strong lead developer. If it is “should we build this at all, and what does it commit us to”, you need CTO judgement.

Headcount alone does not answer this. Consider the complexity of the platform, the number of teams to coordinate and the decisions the business needs technology leadership to own.

For occasional decision support, an Advisor subscription may fit. For an operational leadership mandate, consider a Fractional CTO. If the need is implementation capacity, TRENDev can scope a delivery mission alongside your lead developer. A free consultation can help define which gap you actually need to fill.

Start with the mandate: what needs to be owned, what authority is required and how much continuity the organisation needs.

A full-time CTO makes sense when leading technology is a sustained executive responsibility across product, people, operations and the board. A Fractional CTO can fit a defined transition, transformation or leadership gap, provided the agreed capacity and authority match the work. It is not a substitute for a full-time role that genuinely needs filling.

There are two different part-time answers. If you need someone to lead a transformation, a governance model or a team through a transition, that is a Fractional CTO: operational leadership with explicitly scoped authority and follow-through. If you need decision support without transferring operational ownership, that is advisory: CTO Advisor or CTO Advisor+.

Choose on the basis of ownership and organisational need, not only hours or price. Compare advisory and Fractional CTO engagements.

Two things happen on a repeating cycle: scheduled strategic sessions, and substantive advice between them.

On CTO Advisor that is typically two strategic sessions a month plus async advice in between. On CTO Advisor+ it is weekly or biweekly sessions, priority async, and a structured Quarterly Technology Review.

Sessions are working sessions, not status updates. You bring the decision that is blocking you, we work it through, and you leave with a position you can act on. Between sessions you send the things that come up: an architecture proposal to review, a hiring shortlist, a vendor quote that smells wrong, a roadmap you want stress-tested.

A Fractional CTO engagement runs differently: its cadence, presence and authority are scoped with you, because the role is to lead and follow through, not only to advise.

• CTO Decision Review, €1,500 one-time excluding applicable taxes. One payment for one technical decision: up to 4 hours in total, a written decision brief and a walkthrough. No subscription and no ongoing access afterwards.
• CTO Advisor, €1,500 per month excluding applicable taxes. Up to 4 hours a month of advisory capacity, typically two strategic sessions, async advice between them. For founders who own execution themselves and want senior judgement reviewing direction.
• CTO Advisor+, €2,500 per month excluding applicable taxes. Up to 8 hours a month, weekly or biweekly sessions, priority async, and the Quarterly Technology Review. For companies where the technology decisions are arriving faster than one session a fortnight can absorb.
• Fractional CTO, from €6,000 per month excluding applicable taxes. Embedded leadership with ownership where scoped: transformation programmes, governance, board and investor work, due diligence, and hands-on execution when explicitly agreed. Contact only, scoped individually, never self-service.
