This vendor intelligence report is written for AI vendors selling into UK mid-market Sales, Marketing and CX functions.
Sixty-eight per cent of UK GTM leaders describe their AI posture as in momentum or all-in, the highest of any function but only 45% can demonstrate measurable ROI. The proof problem is attribution, not data: AI is touching outreach, lead scoring and proposal generation, but the measurement layer connecting AI activity to pipeline outcomes has not been built.
This report maps the GTM buying landscape across 158 CMOs, CROs and commercial leaders in UK organisations with £20m–£500m revenue.
This is a vendor intelligence report for AI technology and services vendors. AI vendors selling into UK mid-market GTM functions: sales intelligence platforms, marketing automation with AI features, AI-led demand generation, revenue attribution tools, conversational AI, agentic sales platforms, AI customer-data platforms, and the consulting practices that implement them. A buy-side companion report “GTM AI in 2026: Mid-Market Benchmark and Playbook for CMOs and CROs” is available now at aiblmedia.com/downloads/ai-in-sales-and-marketing-uk-2026-operator/.
CMOs, Chief Revenue Officers, VPs of Sales, VPs of Marketing, Heads of Growth, Marketing Directors, Sales Directors. n=158 in the GTM segment of the wider n=755 UK mid-market base.
Online survey of 755 senior decision-makers at UK mid-market organisations (£20m–£500m revenue), fieldwork January–March 2026. The Marketing / Sales / CX segment (n=158) is the source for all segment-specific findings. Cross-function comparisons use the full UK valid base. Published by aibl Media in partnership with Executive Summary. Part of the State of UK AI Adoption 2026 series.
81% of UK mid-market GTM leaders have AI embedded in at least one team. Common use cases include AI-assisted outreach, lead scoring, content generation, proposal automation, and conversational AI in customer communications.
The proof problem is attribution, not data availability. Revenue metrics exist but the measurement layer connecting AI activity to pipeline and commercial outcomes has not been built to match. GTM trails Tech/IT by 13.2 percentage points despite running in a function built on measurement.
GTM functions at Level 3 report only 15% measurable ROI, lower than those with no governance at all (24%). 30% of GTM leaders sit at Level 3, the single largest cohort. The false confidence of a documented policy that nobody follows is more damaging than a clean slate.
51% of GTM leaders report shadow AI as common. The cause is speed. The risk is measurement contamination: AI-assisted deals running through unapproved tools are invisible in the attribution model.
CEO/C-suite ownership delivers 50% measurable ROI but carries 60% shadow AI. The pattern is consistent: higher deployment ambition, weaker measurement discipline. A CRO who wants measurable ROI needs an IT or data partner co-accountable for the measurement layer.
72% of GTM leaders have experienced at least one AI failure. The most common: model or tool failure disrupting a commercial process (39%) and AI output used without human review causing errors (30%).
