What is a fractional Chief AI Officer?
A fractional Chief AI Officer (fractional CAIO) is a senior AI leader who works inside your company part-time — owning your AI strategy, roadmap, priorities, risk, and results without the cost of a full-time executive hire. For owner-led ecommerce brands, it is accountable AI leadership sized to the store. At Miller & Miller, clients work directly with brothers Parker and Taylor from roadmap through hands-on Shopify delivery. There is no strategy handoff to a junior build team. The firm brings experience from Google, Spot AI through roughly 160x growth, Stanford Law, and hands-on ecommerce implementation. The client owns the code, process, and know-how.
What a fractional Chief AI Officer does
Senior AI leadership at a fraction of the cost — and leadership that builds and proves the work, not just advises on it.
Owns the AI strategy
Sets the roadmap, decides where AI is worth the most, and makes the calls — what to automate, what to leave alone, what's next. The decisions come off your plate.
Builds it fast
Most fractional CAIOs stop at advice. We turn the roadmap into live CRO tests, support automation, lifecycle flows, dashboards, and store systems.
Proves it in your numbers
Every month you see exactly what moved — conversion recovered, tickets deflected, carts saved — reported in plain English. That is the scoreboard, and we answer for it.
Transfers the capability
You own everything built — the code, process, and know-how. We document what ships and train your team, so nothing is locked inside a black box.
Find. Build. Prove.
No transformation theater. One experienced senior team stays with the work from roadmap through launch, then proves it in your store's numbers every month.

Who a fractional Chief AI Officer is for
It is the right model for a specific kind of ecommerce brand — and an honest mismatch for others.
Owner-led ecommerce brands, ~$1M–$50M
Primarily Shopify and DTC stores where the owner or operator makes the call and there is no in-house AI leadership or build team.
Leaders who want a doer, not a deck
You do not need another strategy advisor. You need an accountable executive and builder who stay with the work from roadmap through launch.
Stores with measurable friction
Conversion leaks, routine support volume, lifecycle gaps, catalog work, and hand-stitched reporting are consuming revenue or capacity.
Not a fit: big in-house AI org
If you already employ an AI/ML team and just need governance, a pure advisory fractional CAIO may be enough.
The clean fit: leadership that builds
You work directly with an experienced senior team that finds the impact, builds it in weeks, and proves it in your numbers every month.

Fractional Chief AI Officer FAQ
What is a fractional Chief AI Officer?
A fractional Chief AI Officer is a senior leader who owns AI strategy, roadmap, priorities, risk, and results part-time. Miller & Miller adds hands-on ecommerce delivery, so clients get working systems and monthly proof rather than advice alone.
What does a fractional Chief AI Officer do?
Three things: find, build, prove. We map the store and rank opportunities by revenue impact, build the selected CRO tests, support automation, lifecycle flows, dashboards, and store systems, then show the impact in your own numbers every month.
How is a fractional CAIO different from an AI consultant?
A consultant's deliverable is usually a document; Miller & Miller's deliverable is a ranked roadmap, working systems, and monthly numbers. Clients work directly with the brothers whose names are on the company, combining real AI operating experience with hands-on implementation.
How much does a fractional Chief AI Officer cost?
Every engagement starts with the Ecommerce AI Opportunity Audit — from $5K, and it's yours to keep either way. Ongoing fractional AI leadership starts at $8K/month, with Embedded/Enterprise engagements from $20K/month; one-time builds start at $5K. That's far below a full-time CAIO's roughly $265K–$400K all-in annual cost, with no recruiting, ramp, or turnover risk.
Does a fractional Chief AI Officer build, or just advise?
Most fractional CAIOs advise on strategy, vendor selection, and governance. Miller & Miller pairs that leadership with hands-on build and delivery. You own everything built — the code, process, and know-how.
When should an owner-led ecommerce brand hire a fractional CAIO?
When you need accountable AI leadership but a full-time executive is overkill, when repeatable work is eating your team's hours, and when you want working systems and monthly proof rather than a strategy deck. The low-risk way to find out is the Ecommerce AI Opportunity Audit — three weeks to a roadmap and the numbers, yours to keep either way.
