Vetted senior technology leaders, available 1 to 3 days per week. Most engagements run 3 to 12 months.
THE ROLE
A fractional Chief Technology Officer takes on the strategic responsibilities of a full-time CTO, but works with your company part-time. The typical engagement is 1 to 3 days per week over a defined period, usually 3 to 12 months.
The core scope covers technology strategy, architecture and platform decisions, the engineering organisation and how it hires, delivery and reliability, and the security and scalability footing the company needs for its next stage. A fractional CTO is accountable for outcomes, not just an architecture diagram. They own the technical roadmap, sit in executive and board discussions, and align engineering with product and the commercial plan the same way a permanent hire would.
The distinction from a technical advisor matters. A fractional CTO carries the function and the decisions: what to build versus buy, how the platform is structured, how the team is held to a standard, how technical risk is managed. An advisor offers input in periodic conversations but does not own the outcome or sit on your leadership team.
Most fractional CTOs work with 2 to 3 companies in parallel, which means they bring pattern recognition from across the market. They have usually led engineering through scaling phases at growth-stage or enterprise companies, and can point to systems and teams they took from early build to a working organisation rather than to advice that never changed how the company ships.
A fractional CTO does not write production code day to day. The role is leadership: they lead the people who build, set the standard for architecture and delivery, and make sure engineering effort connects to a measurable result instead of scattering across work that never reaches customers.
THE DECISION
Two clear profiles and a pragmatic middle path if you are between them.
Hire Fractional When
Hire Fulltime When
Pragmatic Middle-Path
If you are between these two profiles, past your first product build but not yet at a 25-person engineering organisation, or uncertain whether the role justifies a permanent seat, fractional is the lower-risk entry point. A good fractional CTO will build the function, establish what good looks like for architecture and delivery, and help you define the full-time job description from the inside. When the time comes to hire permanently, they can run the process and hand over cleanly.
LIVE
Day rates for vetted fractional CTOs in Europe typically range from EUR 1,200 to 2,500 per day, depending on seniority, domain specialisation, and engagement length. A typical 1-to-2-days-per-week engagement therefore costs roughly EUR 5,000 to 20,000 per month. Longer engagements (6+ months) often come with a discounted rate.
Most engagements run between 3 and 12 months, often beginning with a short technical review and a 90-day plan before settling into an ongoing arrangement. Shorter engagements (under 3 months) are usually framed as advisory. Longer engagements often transition into a hybrid role or hand over to a full-time hire that the fractional CTO helps recruit and onboard.
Yes, that is the standard model. Most fractional CTOs work with 2 to 3 companies in parallel and explicitly avoid direct competitors. Fractionista requires executives to disclose all active engagements to their clients as a condition of listing on the platform.
A fractional CTO owns technology as a strategic capability part-time on an ongoing basis (typically 1 to 3 days per week, 3 to 12 months): strategy, architecture, the engineering organisation, delivery. An interim CTO fills a vacant seat full-time for a fixed period, usually during a transition. A technical advisor offers input in periodic conversations but does not own outcomes, sit on your leadership team, or carry the roadmap into delivery.
Fractional executives on Fractionista typically specialise in one or two domains, with common examples including B2B SaaS, FinTech, HealthTech, deep tech, and regulated industries. When evaluating candidates, look for domain overlap with your business model and a track record of outcomes, not just tenure. Profiles show domain tags and availability so you can assess fit before reaching out.
Yes. Fractionista also covers CFO, CMO, COO, CPO, CHRO, and CAIO, as well as Board Advisory across Europe.
