When a Full CAIO Makes Sense

A full CAIO is best for very large companies with many teams and many ongoing projects.

A full CAIO fits when:

  • Your company is very large.
  • Your team needs daily AI guidance.
  • Your projects run all year and need full time leadership.

When a Fractional CAIO Makes Sense

Most established small businesses do not need a full CAIO. They need strong help without the full time cost. A fractional CAIO gives exactly that.

A fractional CAIO fits when:

  • You want expert help without a full executive salary.
  • You want a clear AI plan that fits your business right now.
  • You want simple and fast results.
  • You want to avoid mistakes and wasted money.

Time Commitment

  • Full CAIO schedule
    They work daily and handle every project from start to finish.
  • Fractional CAIO schedule
    They work in planned sessions and focus on the most important tasks.

Cost Differences

A full CAIO has a full salary and benefits. This is the right choice only when a business needs daily leadership.

A fractional CAIO costs far less. You only pay for the help you need. You avoid the cost of adding another full time executive.

How Each Role Shapes Your Business

A full CAIO shapes long term plans for large companies.

A fractional CAIO improves the systems you already have and helps you move faster without stress.

Flexibility and Growth

A fractional CAIO can grow with your company. You can add more support or reduce it. You stay in control of the cost and commitment.
