Holding·last review12 May 2026

For a services firm under 50 people, paid AI seats pencil at ~5-person firms only when at least 2 of 5 staff are knowledge workers spending more than 10 hours/week on text drafting, and they fail to pencil at 25–40-person firms if the firm-wide rollout includes less than 60% adoption — between those zones, the break-even is determined by adoption rate, not seat price.

Operators register pillar piece on seat-level ROI by headcount cohort. The 60% adoption threshold is editorial synthesis (source:our-estimate) — labelled explicitly in the article. Review triggers: Microsoft Work Trend Index data updates, Anthropic/OpenAI/Microsoft pricing changes, or publication of cohort-specific adoption research for sub-50-person services firms that moves the adoption threshold. Sister claims: OPS-003 (Claude Pro vs ChatGPT Plus solo founder seat decision), OPS-062 (UK sole-trader AI-tool deductibility), OPS-061 (task-delegation framework 1-5 person business).

About this register

The Operators register tracks claims published from practitioner-advisory pieces addressed to solo founders, micro-SMB, and small businesses up to around fifty people. Claims are reviewed on a 30–45 day cadence — tooling and SMB-relevant pricing shift faster than enterprise procurement signals.

Recent corrections in Operators

  • OPS-036 · Partial · 29 Apr 2026

    Initial publication 29 Apr 2026. Status set to Partial at publication because clause 6 commentary references an order-of-magnitude remediation-cost gap derived from the IAPP 2024 AI Governance Profession Report; the report characterises the gap as material but does not publish a precise multiple, so the wording is annotated source: our-estimate. REVIEW: Peter to source a precise figure or amend the commentary.

  • OPS-035 · Holding · 29 Apr 2026

    Initial publication 29 Apr 2026. Status set to Partial at publication because category 5 lacks the same regulatory/cited-consequence anchor as categories 1-4. REVIEW: Peter to confirm category 5 evidence base and either upgrade to Holding (with strengthened citation) or amend the claim to four categories.

  • OPS-034 · Holding · 29 Apr 2026

    Initial publication 29 Apr 2026 with status=partial. Cost-side claims (vendor pricing) verifiable against the four cited pricing pages on the publication date. Time-recovery claim (90+ min compressed to ~20 min) drawn from published productivity-blogger benchmarks rather than Peter-run measurement; first-cohort replication on the publication's tracked operator cohort due by 13 Jun 2026. REVIEW: Peter.
