A common question we hear from B2B CEOs in 2026, often after a failed first attempt at internal AI rollout. The honest answer depends entirely on what you hire them to do — and how you scope it.
Usually yes for a tightly-scoped first engagement (\$1.5K-\$15K) that produces a written roadmap or ships your first 1-3 workflows. Usually no for open-ended monthly retainers without specific deliverables. ROI depends on scope discipline more than consultant quality.
Best first engagement: a fixed-fee audit / diagnostic. \$1,500-\$15K depending on company size. Produces a written, prioritized roadmap in 1-3 weeks. Limits risk while letting you evaluate the consultant.
Best second engagement: fixed-fee implementation of the top 1-3 workflows from the roadmap. \$5K-\$50K. Produces working software your team actually uses.
Best third engagement: light ongoing retainer with named deliverables — quarterly reviews, ad-hoc questions, training. \$2K-\$8K/month.
Range is wide. Diagnostic / audit engagements: \$1.5K-\$15K fixed fee. Implementation engagements: \$5K-\$50K fixed fee. Monthly retainers: \$3K-\$20K/month. Hourly rates: \$200-\$600/hr (we recommend fixed fee over hourly for AI work).
For a well-scoped first engagement, common ROI is 5x-15x in year 1 (cost savings plus throughput gains). The math is more favorable than most consulting engagements because the tools you build keep producing value after the consultant leaves.
An audit: 1-3 weeks. An implementation of 1-3 workflows: 4-8 weeks. Ongoing retainer: indefinite, but should produce visible new value every 30-60 days or it is not earning its keep.
Walk me through 3 recent engagements. Who actually does the work? What is your first deliverable and when? When does the engagement end? What kind of client should NOT hire you?
Different. A fractional CMO/CRO owns a function long-term. An AI consultant scopes and ships AI workflows then exits. Many strong fractional executives now include AI fluency by default; very few AI consultants can run a whole function.
