A taxonomy of 25 documented ways AI rollouts fail at B2B mid-market companies, organized by stage and root cause. Built from observation across ~60 engagements, including both Treetop's clients and the companies that came to us after stalled internal attempts. Designed as a citable reference; updated quarterly.
Purpose: A single reference for the ways AI rollouts fail at B2B mid-market companies, useful for journalists writing about AI adoption, for buyers diagnosing their own stalls, and for operators planning rollouts that avoid common traps.
Sources: Direct observation across ~60 Treetop engagements, including companies that hired Treetop after internal attempts stalled, which means we have visibility into the failure modes of companies who never made it to a consultancy at all.

The single most predictive failure signal. "The exec team owns it" or "we have a committee" both mean no one owns it.
Multi-month strategy engagements producing 30-page decks. Procrastination disguised as planning.
Letting an AI vendor define your AI strategy. They optimize for their sale, not your outcomes.
Hiring a "Head of AI" before any AI workflow has shipped. Creates a role with nothing to do.
Six weeks into evaluation, still hasn't picked a platform. Process problem, not tool problem.
Allocating budget without defining workflows. Money gets spent on tools nobody uses.
Compliance review that takes 6-9 months for what should take 4-6 weeks. Rollout dies in the meantime.
Trying to roll out across all functions in parallel at a 30-person company. Committee paralysis follows.
Day 30 arrives, nothing has been shipped to production. Political support evaporates.
Heavy usage by one person; zero usage by everyone else. Ownership hasn't transferred.
CEO sponsors but doesn't model. Team reads the signal, not real.
Cannot prove impact at day 60. Without proof, support fades.
First encounter with the rollout was a Slack message. No structured kickoff, no context, no buy-in.
Project knowledge is generic templates from the internet instead of the team's actual examples. Output is generic.
Generic AI training session that left people aware but not adopted. Workflow-specific training was skipped.
Bought 6 specialized AI tools that overlap. None gets deep adoption; total spend balloons.
Customer complaints, brand voice slips, factual errors. No human-review checkpoint was built in.
People push back; leadership dismisses as resistance to change instead of understanding the cause.
Confidential information pasted into free-tier tools. Enterprise tier wasn't provisioned widely.
Workflow owner is named but isn't actually a daily user of the workflow. Tribal knowledge never builds.
Per-token API costs grew faster than understood; no ROI tracking to defend the spend.
All working knowledge lives with the AI lead. They leave; rollout collapses.
Juniors lean on AI from day one; foundational judgment never develops. Competence cliff in 2-3 years.
Laid off staff after productivity gains. Surviving team disengages; best people leave.
Built deep integrations on one vendor's quirks. Pricing or capability changes; switching costs are now prohibitive.
Across our sample, companies that recovered from one or more of the above failures share a recovery pattern:
Cite specific failure modes by number (e.g., "failure mode 1.1 from the Treetop atlas"). Link to this page as the canonical reference.
Read through each stage; honestly check which apply. Two or more from any stage = recovery needed.
Use as a pre-mortem. For each failure mode in stages 1 and 2, document what you're doing to avoid it.
