Choosing the Right AI Leadership for Your Business: Full-Time Head of AI vs AI Consultant vs Fractional Head of AI

The race to harness artificial intelligence is in full swing. Across industries and boardrooms, the conversation is the same: how do we make AI really work for us and who owns the AI roadmap?

The titles can be confusing – AI Consultant, Head of AI, Fractional Head of AI. But this isn’t just semantics. It’s a strategic decision that shapes whether your AI projects deliver real ROI or burn cash.

At Head of AI, we believe leadership makes the difference. Here’s how to tell which option is right for your business.

The AI Consultant: The Specialist on Call

AI Consultants are problem-solvers. You bring them in to fix a well-defined issue – like running a proof of concept in NLP or auditing an existing algorithm.

Hallmarks

Project-based: Clear scope, clear deliverables.

Advisory role: They recommend, you execute.

Short-term: Engagements usually end when the project does.

When to hire one:

• You’ve got a single AI problem with an in-house team ready to implement.
• You need a one-off audit.
• You need rare expertise you don’t want on payroll.

Analogy: Like calling in a lawyer for a tricky contract – you don’t keep them on retainer.

The Full-Time Head of AI: The In-House Visionary

A permanent senior executive tasked with building and running your AI capability. They set the roadmap, build teams, fight for budget, and make sure AI is stitched into every corner of the business.

Hallmarks

• Permanent hire: Senior leader or C-suite role.
• Strategic + operational: From vision to governance.
• Big investment: Salary, benefits, long-term commitment.

When to hire one:

• You’re a large enterprise or well-funded scale-up betting your model on AI.
  
• You want to own AI leadership in-house.
• AI runs through every vein of the company.

Analogy: Like hiring a full-time Head of Estates to manage every blueprint and every brick of your new HQ.

The Interim Head of AI: The Change Agent

Think of this as a Head of AI on a time-limited contract. Brought in to bridge a gap, lead a transformation, or steer a critical initiative.

Hallmarks

• Contract-based: 3–12 months.
• Strategic + hands-on: Brings authority without permanence.
• High-impact: Designed to deliver change quickly.

When to hire one:

• You’re between permanent hires.
• You’re running a major change programme.
• You need instant senior capability to get started.

Analogy: Like parachuting in a seasoned COO to stabilise during a restructure.

The Fractional Head of AI: The Smart, Strategic Partner

This is where we come in. A Fractional Head of AI gives you the strategic leadership and
embedded expertise of a full-time hire, but only for the fraction of time you need.

At Head of AI, this is our model. We deploy seasoned AI leaders into your business for a set
number of days each month. They don’t just advise – they build the strategy, oversee
execution, enable your team and scale your capability.

Hallmarks

• Long-term, part-time: A partner, not a project.
• Cost-effective: C-suite calibre without the full-time burn.
• Embedded: They know your people, your culture, your challenges.
• Flexible: Engagement can scale up or down as you grow.

When to hire one:

• You’re a scaling SME that needs AI leadership but can’t justify a full-time Head of AI.
• You want a robust AI strategy that matures with your business.
• You need someone who can support your team, brief your board, and impress your investors.
• You want to reduce the risk of a costly mis-hire at senior level.

Analogy: Like working with a Fractional Finance Director – you get high-impact leadership
on tap, but not on payroll
