Your fractional CTO can also drive your AI transformation

Beyond classic tech leadership, our CTOs are increasingly stepping in on a topic many CEOs have in mind but don't know where to start: turning AI into a product delivery accelerator. In practice, that means industrializing your AI-assisted development workflows, reviewing auto-generated code, and helping your teams adopt these new practices without losing quality. It's not a separate project: it's a natural extension of the CTO mission.

FAQ

A fractional CTO is an experienced tech leader who works with your company on a fraction of their time (usually 1 to 3 days a week). They handle the technical strategy, team management, architecture decisions, and the interface between business and tech, exactly like a full-time CTO, but without the cost and commitment of a permanent hire. It's the ideal solution for startups that don't yet need, or can't yet afford, a CTO dedicated 100% of the time.

A full-time CTO is fully dedicated to your company, which makes sense once your technical challenges justify the cost (usually from a team of 5 to 10 developers). A fractional CTO brings the same strategic expertise over a volume of days suited to your growth stage. Key benefit: you get access to a senior profile you couldn't hire as a permanent employee at this stage, with full flexibility on duration and volume.

CO-CTO's fractional CTO rate is based on a day rate of €800 to €1,500, depending on the profile and the mission. The number of days per week is defined together based on your needs. It's significantly cheaper than a permanent hire (a senior CTO represents a €120K to €200K annual package), with zero risk and full flexibility.

A fractional CTO is especially well suited to early-stage startups or those still finding their footing (seed to Series A), scale-ups going through a CTO transition, SMEs looking to accelerate their digital transformation, and companies that need occasional expert input. If you have a technical team but no clear strategic vision, it's often the best solution.

At CO-CTO, the typical time to get started is 1 to 3 weeks. We start with a scoping workshop to understand your challenges, then suggest one or more profiles from our collective (600+ experienced CTOs). Once the profile is confirmed, the mission can start quickly with structured onboarding so your CTO is up and running from day one.
