For a solo founder processing 100-300 emails a day in 2026, the cheap-stack option (Gmail labels + Claude Pro at $20/month + a 5-line prompt template) recovers roughly 90% of the value of an $83/month premium stack (Superhuman AI + Shortwave Pro + Reclaim.ai Pro) at about 24% of the cost. The premium stack is worth its price under three conditions only — 2+ hours/day in email, keyboard-shortcut speed gain that pays back at the founder's hourly rate, and a documented bottleneck the cheap stack failed to solve after a two-week trial. Without all three, the founder is paying for an aesthetic, not measurable productivity.
Operators-register procurement piece. Cheap stack costs $20-27/month, premium stack ~$83/month, both pulled from vendor pricing pages on 28 Apr 2026. The 90-to-20-minute triage compression is grounded in published productivity-blogger benchmarks (Cal Newport, Tiago Forte, Khe Hy) — not Peter's personal measurement. Status set to Partial at publication because the supporting time-recovery figure (90+ minutes to ~20 minutes) is synthesized from external practitioner writing rather than a Peter-run benchmark; the cost math is verifiable on the cited pricing pages but the productivity claim needs a tracked-cohort replication to move to Holding. 45-day review: vendor pricing shift, Gmail filter/label changes, Superhuman or Shortwave shipping a price drop or feature gap-widener, native Gmail integration from a consumer-AI vendor.

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.

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.

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.

Trigger condition (2) fired: the effective date moved. Governor Polis signed SB 26-189 on 14 May 2026 (Holland & Knight client alert, May 2026; Seyfarth; Littler). The signed law repeals and reenacts the original Colorado AI Act and its obligations take effect 1 Jan 2027 — not 30 Jun 2026 as the claim asserted. No operator obligation starts 30 Jun 2026; the only pre-2027 item is Colorado AG rulemaking due by 1 Jan 2027. The claim's structural reading holds (risk-management programmes and impact assessments dropped for a notice-and-transparency framework; consequential-decision scope covering employment, housing, credit, insurance, education, healthcare; no small-firm exemption). The urgency leg ('obligations from 30 June 2026') is overtaken. Status Up → Partial.
