Fractional executive leadership
Choose the executive lane that matches the bottleneck. Fractional CTO, CIO, and CEO coverage through published NullCXO subscriptions, or scoped advisory when the work is heavier than a standard package.
Standard NullCXO rates start at $275/hour. Monthly retainers start at $2,750 for 10 hours. Turnarounds, transformations, and other heavy executive work are scoped separately, starting at $337.50/hour (not standard NullCXO package pricing).
Fractional CTO, CIO, and CEO
Match the role to the problem
Use fractional leadership when technology direction, vendor decisions, delivery risk, or operating priorities need senior accountability without a full-time executive hire.
Fractional CTO
Architecture, engineering direction, roadmaps, and delivery governance when build and ship are the constraint.
Fractional CIO
Systems, vendors, and technology spending when governance and priorities need an operator, not another tool purchase.
Fractional CEO
Company direction, priorities, and accountability when technology is central to how the business runs and decides.
Delivered through NullCXO

FAQ
What is fractional executive leadership?
Part-time CTO, CIO, and CEO coverage: senior technology and business leadership on a published monthly retainer or hourly plan, without hiring a full-time executive.
How do fractional CTO, CIO, and CEO differ?
CTO focuses on architecture, engineering, and delivery. CIO focuses on systems, vendors, and technology spending. CEO focuses on company direction and accountability when technology is central to the business. Many engagements blend elements; we align the role to your bottleneck.
