Why this is in the vault
CJ's business-history deep dive on corporate aviation (Sam Walton's Ercoupe through the Tyco/Kozlowski jail sentence and Immelt's GE "shadow jet") plus the weekly public-comp valuation/efficiency benchmark set, worth keeping both for the SEC-disclosure mechanics and the recurring reference data.
Issue contents
- Fire Up the Gulf Stream! The History of Corporate PJs — business-history essay. Traces corporate aviation from Sam Walton's frugal 1950s store-scouting flights (Walmart Aviation, the 1980s "Flight Grid," today's ~15-22 jet fleet) through the modern financial-statement mechanics: how personal jet use hits the DEF 14A proxy under SEC Regulation S-K Item 402 once perks exceed $10k/year, the three ownership tiers (charter → jet card → fractional → own, driven by annual flight hours: 0-50/50-200/200-400/400+), and 100% bonus depreciation under IRC Section 168(k) as restored by the One Big Beautiful Bill Act. Two fraud case studies: Gulfport Energy's 2021 SEC cease-and-desist ($88k fine, CEO resignation) and Tyco's Dennis Kozlowski (convicted of grand larceny, ~7 years served, $134M restitution) for the Sardinia birthday-party jet abuse. Covers ADS-B flight tracking (Jack Sweeney's @ElonJet) as the forensic-investor workaround for financial-statement opacity, and closes on Jeff Immelt's GE "shadow jet" (empty backup plane trailing his own) as the case study tying private-jet excess to governance failure — Immelt was forced out in 2017, and his successor's first act was liquidating the fleet.
- Weekly Valuation and Efficiency Metrics — recurring benchmark report across the same 9 named tech sectors (Security & Identity, Data & AI Infra, Dev Tools & Observability, Horizontal SaaS, GTM/MarTech, Vertical SaaS, Take-Rate Platforms, Payments, Consumer Fintech/Crypto). Covers NTM revenue multiples, CAC payback period, revenue-per-employee, Rule of 40, and OPEX bucket breakdown. Methodology unchanged from prior issues.
Mapping against Ray Data Co
The core mechanism CJ documents — SEC Regulation S-K Item 402 forcing disclosure of any executive perk over $10k, converting private "trust me" spending into a mandatory public paper trail — is the inverse of the trust posture RDCO runs on internally. RDCO has no board, no proxy statement, no external capital forcing disclosure; the founder's spending judgment is self-policed. The governance research CJ cites (Journal of Financial Economics: CEOs who flew private extensively underperformed the market by ~4%/year, correlating not because the jet caused it but because the entitlement that permits jet abuse correlates with reckless decision-making elsewhere) is a useful outside data point for user_money_values_potential_tension — the accumulate-to-enjoy inflection the founder is navigating. The signal isn't "don't spend," it's that unexamined discretionary spend is a leading indicator worth watching for, the same way CJ argues forensic investors watch ADS-B data because the financials themselves are opaque by design. No RDCO-specific artifact to reuse here (no fleet, no proxy statement, no NEOs) — this is a governance-pattern read, not a tactical one.

⚠️ Sponsorship
Abacum is the paid sponsor (per the known sender watchlist) — two ad placements at the top of the issue promoting Abacum's "Scenario Planning" FP&A product, with UTM-tagged partner links (utm_source=mostly-metrics&utm_medium=partner). Koyfin is credited as the data source for all benchmark charts and gets its usual affiliate plug at the end of the "Companies Included" section (?via=metrics link) — known recurring affiliate partner, not new to this issue. Bias implication: neither sponsor's product is referenced in the corporate-jets essay itself; sponsorship is placement-only (ad blocks bookending unrelated content), not content-shaping.
