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.
Re-review 10 Jun 2026: the pricing-changes trigger fired, in the claim-strengthening direction. claude.com/pricing (fetched) now lists Claude Team standard at $20/seat/mo annual, $25 monthly (premium seat $100/$125) versus the $30 in the article's pricing table; Microsoft now sells an SMB 'Microsoft 365 Copilot Business' SKU at $18/user/mo promotional through 30 Jun 2026 ($21 after) on the page the article cites at $30 (the $30 enterprise list is unchanged on the enterprise page); Claude Pro ($17 annual / $20 monthly) and ChatGPT Business ($20 annual / $25 monthly) match the article. Cheaper seats lower the 5-person penciling threshold and reinforce the core assertion that break-even is adoption-rate-determined, not seat-price-determined — the claim text carries no specific prices and holds. The article pricing table (lines 58-64) is now stale on two rows and needs a Peter-approved refresh pass. 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).

Source-text re-review: the '$300-$500 (2024) toward $100-$130 (early 2026)' median trajectory is not stated in either cited source — the Godberry Studios teardown reports stack cost by revenue tier (not a year-over-year median) and BetterCloud's SaaS-industry data covers enterprise spend, not solopreneur AI subscriptions. The compression direction is supported by the Godberry tier data and observable foundation-model bundling; the specific year-anchored median figures are reclassified as source:our-estimate in the article. The load-bearing claim (active compression / category-collapse) holds; status moved to Partial pending a primary source carrying a dated solopreneur-median series.

One named member of the generation cluster was already defunct at publication: Tome shut down its presentation/narrative product (Tome Slides) in March 2025 and pivoted to sales tooling, with the brand later sold to AngelList (deckary.com shutdown timeline; signalhub.substack.com post-mortem, both checked 10 Jun 2026). The generation cluster reduces to Pitch + Gamma. The two-cluster thesis itself is unaffected and arguably strengthened — the pure AI-narrative product failed to find a sustainable business while Gamma (70M users, $100M ARR as of Nov 2025) and the assembly cluster (PandaDoc, Better Proposals, Proposify per Luniq 2026 agency comparison) both compound. Status Up → Partial for the factual error in the tool list.
- OPS-022 · Partial · 10 Jun 2026
Vendor attribution error in the claim text. The claim names Polley Faith among 'Spellbook with named small-firm customers Westaway, KMSC Law, Polley Faith'. Polley Faith LLP is a Harvey-listed law-firm customer, not a Spellbook customer: the live Spellbook site (now spellbook.com; spellbook.legal 301-redirects) names Westaway, KMSC Law, and McInnes Cooper with no Polley Faith, and the source article's own body correctly places Polley Faith on Harvey's roster — the claim text and the article excerpt bundled it with the wrong vendor at publish. The remaining legs verify against extracted source text on 10 Jun 2026: Anthropic's GC AI customer story carries 'More than 1,500 companies' and '14 hours saved per week on average ... based on a survey of more than 100 active customers' verbatim; Harvey's published roster (Thompson Hine, Fox Rothschild, Lowenstein Sandler, Polley Faith) matches; ABA Formal Opinion 512 remains the governance baseline. The corpus reading (AI ships at 1-to-20 lawyer scale; privileged work stays on Enterprise-tier zero-retention access) is unaffected. Status Up -> Partial.
