A head of AI, also published as Chief AI Officer or CAIO, owns AI strategy, governance and oversight, and acts as accountable leadership for responsible AI. A fractional head of AI fills the role part-time on a retainer, a model McKinsey found 62% of European firms prefer, citing 30-50% cost savings.
The dominant term is country-specific: CAIO externalisé in France, fractional head of AI or fractional CAIO in the UK, and externer Head of AI in Germany, where LinkedIn ranked Head of AI the fastest-growing job title for 2026.

A fractional head of AI, also called a fractional CAIO (chief AI officer), is a senior AI leader engaged part-time to own AI strategy, governance and EU AI Act readiness. For a fractional or outsourced offer, European buyers search the executive title rather than the individual-contributor AI engineer title. The role is called CAIO externalisé in France and externer Head of AI in Germany.
UK rates run roughly £900 to £1,600 per day or £4,000 to £6,000 per month at 2 to 3 days per week (fractional.quest). France sees published retainers of €4,500 to €8,000 per month (humaloop.fr). Germany runs roughly €700 to €1,300 per day. The fractional CAIO benchmark is still emerging, with fractional CTO pricing plus an AI premium used as a proxy.
A fractional CAIO fits when a company needs AI strategy, governance and EU AI Act compliance but cannot justify a full-time AI executive. McKinsey reports 62% of European enterprises prefer fractional or outsourced AI leadership, citing 30 to 50% cost savings, and Gartner notes 68% lack a formal AI governance framework.
Fractional head of AI and fractional CAIO describe the same part-time executive leadership with decision authority over AI strategy and governance. An AI consultant delivers project-scoped advice without ongoing leadership or team management. Fractional AI leaders typically coordinate consultants and AI engineers within a strategy they own.
The EU AI Act, in force since August 2024, applies high-risk system obligations from August 2026 and Annex III obligations by December 2027, with penalties up to €30M or 6% of global turnover. This creates a GDPR-style compliance driver, and a fractional head of AI is a cost-efficient way to build governance ahead of the deadlines.
A head of AI owns strategy, governance, roadmap and board reporting. An AI engineer is a hands-on individual contributor who builds and ships AI systems. They are complementary: the head of AI sets direction and compliance, the AI engineer delivers the build. Many engagements use a fractional head of AI directing freelance AI engineers.
Define the AI mandate and governance scope, set a days-per-week commitment (2 to 3 typical), then shortlist specialist marketplaces and boutiques with sector and EU AI Act experience. Validate references and a governance track record, agree a retainer, and review against a 90-day AI readiness and roadmap plan.
