Buyer's question

AI Rollout Mistakes by Company Size The mistakes shift by stage.

Generic "AI rollout best practices" miss that the failure modes change dramatically by company size. A 15-person company fails differently than a 150-person one. Here's the size-specific guide.

Short answer

At <20 people: too much DIY, no documented learnings. At 20-50: too many tools, no named owner. At 50-150: committee paralysis, plans that never ship. At 150-500: enterprise paralysis, IT bottlenecks, vendor-driven instead of business-driven. Diagnose by size; fix specifically.

500+ people — beyond our advice

At 500+, the playbook is genuinely different. Different governance, different tooling, different risk profile, different vendor relationships. We are not the right advisors for this segment; engagements at this scale should go to firms specialized in enterprise rollout.

FAQ

Where do most rollouts get stuck?

50-150 person range. Too big for founder-led, too small for enterprise structure. Committee paralysis is the most common failure mode.

Should I model my rollout on a bigger company's?

No. Failure modes scale with size. Borrowing a 500-person playbook at 50 people produces paralysis.

What if I'm growing fast and span multiple stages?

Plan for the stage you'll be in 12 months from now, not today.

Should we hire a Head of AI?

Almost never at <100 people. Usually right at 250+. The window in between is judgment-call.

Can outside help fix the wrong-stage problem?

Yes — sometimes the most valuable thing a consultant does is steer you away from over- or under-scoped rollouts.
