Scan #012: Advantages on a timer

Eight companies whose edge has an expiry date — Shepherd, Mainspring, Loop, Archive, Sunrun, Epicor, Dollar General, and Ferguson.

The thread running through today’s eight: every one of them is working an advantage with a clock on it. A tax-code loophole Congress has already scheduled for demolition, a turbine shortage that ends when lead times normalize, a capacity partner who could become the acquirer, a self-imposed 2028 deadline that invites every rival to the table. The question in each case is whether the position hardens into something durable before the window closes.

Shepherd — Insurance · Emerging. A San Francisco MGA (YC W21, $67M raised) underwriting construction and AI-infrastructure insurance off live jobsite telemetry from Procore, OpenSpace and Samsara — 7x revenue growth in 24 months, $400B+ of insured project value. But it books commission on other carriers’ paper, its new anchor investor Intact is also its capacity provider, and its most conceptually dangerous rival is its own seed investor: Procore runs a risk-advisory arm on the same telemetry thesis. Every operating metric is company-reported; no GWP or loss ratio has ever been published.

Mainspring Energy — Energy · Emerging. Menlo Park maker of linear generators — flameless, two-moving-part machines that turn natural gas, hydrogen or ammonia into electricity — with $800M+ raised from Khosla, Gates, General Catalyst and a strategic who’s-who. The uncomfortable number: fifteen years in, it has only tens of megawatts in the field while Bloom Energy booked ~$20B of backlog selling into the same data-center power panic. Founder Shannon Miller stepping aside for Cummins’ ex-CEO in June 2026 is the company’s own admission that the constraint is now manufacturing, not physics.

Loop — Logistics · Emerging. AI-native freight audit and payments founded in 2021 by two Uber Freight architects; ~$160M raised including a $95M Series C led by Valor in April 2026, with carrier payments running on J.P. Morgan rails. What other coverage missed: Loop has published no traction number of any kind — no volume, no customer count — since October 2023, through two fundraises, and its take-rate-on-freight-spend model meant the freight recession mechanically shrank its own revenue. Its independent review surface is essentially empty.

Archive — Ecommerce / Retail · Emerging. The SF resale-as-a-service platform behind ~60 branded secondhand programs (The North Face Renewed, lululemon Like New), $54M raised, ~3x GMV growth in 2025. Months after it took lululemon from market leader Trove, ThredUp made its rival offering completely free — leaving Archive charging a SaaS fee plus a reported ~30% take in a category where the software layer is now given away and single-SKU processing costs sank far larger players.

Sunrun — Energy · Incumbent, at risk. America’s largest residential solar company — 1M+ subscribers, ~$3B of 2025 revenue, $14.8B of debt against a ~$4B market cap — and the last scaled survivor of a bankruptcy wave that took SunPower, Sunnova and Mosaic. Its “OBBBA winner” story hides that the 48E credit averaging 42.6% of system value sunsets after 2027, and it has quietly filed 420+ lawsuits against its own Massachusetts customers while Connecticut’s AG alleges forged contracts.

Epicor — Supply chain · Incumbent, well positioned. The 50-year-old vertical ERP vendor for mid-market manufacturers and distributors — $1.25B revenue, passed between four PE owners at rising prices, CD&R paying $4.7B in 2020 after KKR ran a $2.75B dividend recap on the way out. In January 2026 it put an expiration date on its own moat: on-prem feature releases end 2028, forcing 23,000+ customers into re-implementation — the one moment rivals ever get a shot at a base that never churns.

Dollar General — Retail · Incumbent, well positioned. The largest US retail chain by store count — 20,893 rural small-box stores, $42.7B in fiscal 2025 sales. The turnaround is further along than the narrative: +3.0% comps, 34% EPS growth, shrink fixed, and format twin Family Dollar fire-sold for one-eighth its 2015 price. The risk is the calendar: Todd Vasos hands the keys in January 2027 to a grocery outsider, and DG’s last CEO transition halved the equity in a year.

Ferguson — Construction · Incumbent, well positioned. North America’s largest trade distributor of plumbing, HVAC and waterworks — $31.3B calendar-2025 revenue, ~1,517 branches. While housing stays frozen, it has quietly become an AI-infrastructure supplier: one disclosed data-center job involves 57,000 valves and 12 miles of copper pipe, part of a claimed ~$90B megaproject pipeline through 2031. The new variable is QXO — the first Ferguson-scale consolidator the industry has seen, building an $18B+ empire in the adjacent aisles.
