Who should own AI in your business?

Read moreCustomer experience is where AI is landing most visibly, and where the return is proven least. In aibl’s survey of 755 UK mid-market business leaders, teams with a customer-facing view report better conversion (64%) and faster response times (62%), yet the marketing, sales and CX pillar records the lowest measurable ROI of any function at 45%. The improvement customers feel has not yet shown up as a number the finance team can review.
The gains are real where customers feel them. Among leaders with a customer-facing view, 64% report better conversion and 62% faster response times. This is not pilot activity; it is AI changing the experience customers actually have.
That makes CX one of the clearest places AI is earning its keep. The problem is not whether it works. It is whether anyone is measuring the result in a form the business will accept.
The marketing, sales and CX pillar reports the lowest measurable ROI of any function, at 45%, and the highest failure rate, at 85%. The gains are visible to customers but invisible to finance, because revenue teams measure activity early and outcomes late.
The missing piece is attribution: the line connecting AI spend to conversion and response gains in a form the CEO reviews. Our guide to building an AI business case your CFO will approve covers how to write that metric in first.
Customer-facing teams carry the highest shadow AI use of any function, at 64%. Under deadline pressure, people reach for whatever tool is fastest, approved or not.
Across the survey, shadow AI falls from 75% where governance is weakest to 35% where it is mature. The answer is a faster approved route, not a ban. Our piece on why staff use unapproved AI tools sets out why speed beats policing.
For all its activity, CX has the weakest governance progression in the survey. The pillar’s move from a written policy to an enforced one lifts measurable ROI by just 8 points, the smallest of any function.
That is the gap to close. Better governance is what turns visible customer gains into a return the board can trust. Our analysis of how governance drives AI ROI shows the size of the lever.
Measure the gains you already have. Pick the conversion or response metric AI is moving, record today’s baseline, and report against it a quarter later so the improvement counts as return.
Then give teams a fast, approved toolset to cut the 64% shadow AI, and put a named owner on the outcome, because AI with no single owner returns just 18% across the survey. Our analysis of who should own AI covers the ownership data.
Yes, visibly. In aibl’s survey of 755 UK mid-market business leaders, teams with a customer-facing view report 64% better conversion and 62% faster response times. AI is changing the experience customers have; the gap is measuring that as a return the business can see.
Because the gains are measured late, if at all. The marketing, sales and CX pillar reports the lowest measurable ROI of any function at 45%, since activity is tracked early and outcomes late. The fix is attribution: connect the conversion and response gains to the AI spend that produced them.
The highest of any function. In aibl’s survey of 755 UK mid-market business leaders, 64% of the marketing, sales and CX group report common shadow AI. It signals the approved route is too slow, and it falls from 75% at the weakest governance level to 35% at the strongest.
Measure the gains you already have. Choose the conversion or response metric AI is moving, record the baseline, and report against it. Then provide a fast approved toolset to reduce shadow AI, and name an owner, since unowned AI returns just 18% across the survey.
