Scan #022: Who owns the rail

Eight companies sorted by one question — do they own the transaction layer or rent it: Fleetio, Comulate, ShopMy, Radiant, Talen, US LBM, Alliant, Kroger.

The thread running through today’s eight is control of the rail — the layer where the transaction actually clears. Fleetio spent $454M buying the authorization rail it used to sit beside; Comulate is in federal court because the incumbent that owns the data rail cut it off; ShopMy’s premium depends on staying the neutral pipe while the retailers who own checkout build their own; Radiant is betting a factory can out-ship the diesel supply chain. On the entrenched side, Talen owns the scarcest rail in America — licensed nuclear megawatts next to fiber — while US LBM, Alliant, and Kroger show three fates of owning physical distribution: leveraged, weaponized, and eroding.

Fleetio — Logistics / Fleet software · Emerging. Birmingham, Alabama fleet-maintenance software at $4-10 per vehicle per month, bootstrapped four years, now $624M raised at a $1.5B valuation after a $454M Series D (March 2025) that bought Auto Integrate — the authorization rail behind 13M repair orders a year across 110,000+ shops. The wrinkle other coverage missed: that rail’s volume is routed largely by fleet-management companies that compete with Fleetio for the same fleets, and Samsara and Motive are bundling maintenance into the telematics subscription that already owns the engine data. Fleetio has never disclosed ARR.

Comulate — Insurance software · Emerging. San Francisco AI that automates commission reconciliation for insurance brokerages — 8-figure revenue in under three years on only ~$25M raised, backed by BOND and Workday Ventures. The story is now a courtroom: Applied Systems sued for trade-secret theft over a fake agency inside Epic (Nov 2025), won a preliminary injunction barring Epic-derived sales to new customers (Feb 2026), and by May 2026 court filings disclosed ~20% layoffs and customer defections; Comulate’s Sherman Act countersuit says the incumbent is weaponizing data access to kill a rival. The open question is whether a startup can survive when the system of record it reads from is owned by its adversary.

ShopMy — Ecommerce / Creator commerce · Emerging. The affiliate-commerce layer for prestige brands — 200,000 vetted creators, 1,200 brands, $1B+ in annual platform sales, an estimated $80M of 2025 revenue up 196% (Sacra), and a $70M Series C at $1.5B (Oct 2025). The threat is disintermediation from both ends at once: Sephora launched its own creator storefronts in October 2025, Walmart and Amazon are pulling creators in-house, and TikTok Shop collapses discovery and checkout into one feed — squeezing a middle layer that takes 2.9-3.9% of GMV for staying neutral.

Radiant — Energy / Nuclear · Emerging. El Segundo microreactor company founded by a SpaceX veteran, trying to mass-produce truck-transportable 1 MW reactors that replace diesel generators; ~$575M raised at a $1.8B valuation (Dec 2025-Jan 2026), first slot in DOE’s DOME test bed, TRISO fuel delivered July 1, 2026. What the funding announcements omit: four DOE-pilot rivals reached zero-power criticality first, academic microreactor cost estimates run $140-410/MWh against the diesel it claims to beat, and the Oak Ridge factory is being built ahead of any commercial license — with revenue at zero.

Talen Energy — Energy / Power · Incumbent, well positioned. The Houston IPP that proved the nuclear-to-hyperscaler model: sold Amazon the campus next to its Susquehanna reactor for $650M (March 2024), fought FERC for eighteen months, and converted it into a grid-connected PPA of up to 1,920 MW through 2042 — roughly $18B of contracted revenue (Power Magazine). Now ~15.5 GW after the Cornerstone gas closing (June 2026) at an ~$18.4B market cap. The asterisks: everything outside Susquehanna is merchant gas in a PJM where politicians are reaching for price caps, and the fleet is concentrated on a single nuclear site.

US LBM — Construction / Building materials · Incumbent, at risk. One of the largest US specialty building-products distributors — 443 locations, built by L.T. Gibson from three lumberyards in 2009 to $11.5B revenue in 2022, co-owned by Bain and Platinum at a reported ~$7B enterprise value (Oct 2023). Fiscal 2025 revenue of $6.8B is down roughly 40% from peak, secured debt was refinanced at a 9.5% coupon, and S&P cut the outlook to negative in March 2026 — a leveraged bet on a housing recovery that keeps not arriving, while Builders FirstSource and Home Depot’s SRS consolidate around it.

Alliant Insurance Services — Insurance / Brokerage · Incumbent, well positioned. The fourth-largest US business insurance broker — $5.7B+ revenue and ~$55B premium placed in 2025 — built not on roll-up M&A but on the industrialized producer “lift-out”: hiring entire specialty teams from rivals, guaranteeing comp, paying in employee equity, and litigating the non-competes as a routine cost. S&P upgraded it to B+ in May 2026 even with PE-recap leverage; the model’s exposure is that it is, structurally, a machine for buying talent with debt — and every rival it raids is now copying the playbook.

Kroger — Retail / Grocery · Incumbent, at risk. America’s largest pure-play supermarket operator (~2,700 stores, ~$58B EV) has burned both of its last-decade escape plans: the $24.6B Albertsons merger died in court (Dec 2024, with Albertsons’ breach suit still live), and the Ocado automation bet ended in a ~$2.6B impairment with three fulfillment centers closed in January 2026 and $350M paid to exit. New CEO Greg Foran (ex-Walmart US, from Feb 2026) inherits Numerator share sliding 8.8% to 8.3% since 2024 while Costco passed Kroger going the other way — and the first-ever e-commerce profit (Q1 FY2026) came from shrinking the ambition, not winning the channel.
