CTO as a Service
CTO as a Service in Spain: when to hire a fractional CTO
Published: February 19, 2026
Most mid-sized companies need technical leadership before they can afford a full-time CTO. The CTO as a Service model solves exactly this gap: high-level strategic and technical guidance, without the fixed cost of a senior technology director on the payroll.
What a fractional CTO does (and doesn't do)
- Designs the technical architecture of your product or platform: technologies, infrastructure, data patterns, scalability.
- Leads the selection and management of external vendors: evaluates proposals, negotiates contracts, supervises agency and freelancer deliveries.
- Builds and improves development processes: defines methodology, sprints, code review, deploys, testing, and documentation.
- Connects business and technology: translates business objectives into technical requirements and communicates technical status to management and board.
When it makes sense to hire a CTO as a Service
- Growing startup or scale-up: you have a technical team but no one with scaled architecture experience or technical product vision.
- Company undergoing digitalisation: you want to execute a digital transformation project but your internal team lacks experience with this type of project.
- Post-acquisition company: an acquired company has critical technical debt and you need an unbiased external analysis and remediation plan.
- Before hiring your own CTO: you need to prepare the company so an in-house CTO can succeed — documentation, processes, technical strategy.
How much does a CTO as a Service cost in Spain
- CTO as a Service in Spain: between €3,000 and €8,000/month depending on dedication (from 2 days/week to part-time) and level of responsibility.
- Compared to a full-time CTO: a senior CTO in Spain costs €80,000-€150,000 gross/year plus benefits, equity, and search time. The fractional model is 5-10x more economical.
- Per-project model: for specific projects (architecture design, technical due diligence, technical debt plan), the cost is one-off and fixed.
- Dockia Starter €500: complete technical diagnostic of the current situation, risk identification, and roadmap proposal. No obligation to continue.
