Fractional CAIO: Role, Cost and 90-Day Plan
Understand the Fractional Chief AI Officer role, engagement cost drivers, governance responsibilities, and first 90-day plan.
What the role owns
The Fractional CAIO creates a portfolio view across business units, aligns AI decisions with strategy, defines governance and evidence requirements, coordinates technology and risk leaders, and reports material progress and exposure to executives and the board.
What determines cost
Cost increases with the number and consequence of use cases, regulatory exposure, vendor complexity, data readiness, board involvement, implementation responsibility, and the frequency of executive decisions. A diagnostic, 90-day build, and retainer should be priced differently.
The 30-60-90 sequence
Days 1-30 inventory systems, owners, value, and risk. Days 31-60 prioritize the portfolio and install governance. Days 61-90 move selected use cases through governed operation, test escalation, measure adoption, and transfer ownership.
How to judge progress
Progress is not the number of pilots. Review portfolio concentration, time to evidence, workflow adoption, exceptions, cost, model and vendor risk, human-control effectiveness, and the quality of decisions supported.
Questions executives ask
What does a Fractional Chief AI Officer do?
A Fractional Chief AI Officer helps leadership govern AI strategy, prioritize use cases, manage risk, evaluate vendors, define adoption metrics, and connect AI investment to business value.
How much does a Fractional CAIO cost?
Cost depends on portfolio complexity, governance responsibility, executive cadence, vendor evaluation, implementation support, and whether the role includes board reporting or operating ownership.
When is a Fractional CAIO better than a full-time hire?
Fractional CAIO work fits when the company needs senior AI governance and strategy before the permanent role, operating model, or investment portfolio is fully defined.
What should the first 90 days produce?
The first 90 days should produce an AI portfolio, risk tiers, ownership model, evidence standards, prioritized use cases, and a decision cadence for stopping, repairing, or scaling work.
