We pulled what's in public records for Boone — Census ACS 5-year demographics, County Business Patterns establishment counts, Nonemployer Statistics, BLS Local Area Unemployment trend, USAspending federal awards, IRS Form 990s for institutional anchors. We then ran ground-truth web research across procurement portals (procurement.opengov.com/portal/boonecountyky for the Fiscal Court; kentuckybids.com for school districts), KY Bar Association membership, KY Secretary of State entity records, FAA Part 145 directories, NAHB CAPS directories, IAQG OASIS aerospace cert listings, and the trade press relevant to each sub-economy. Where a primary-source artifact existed (a DHL corporate press release, a state Cabinet for Economic Development announcement, an FAA AIP grant detail, a Lane Report investment story), we cite it.
Four caveats shape what we have not verified. First, we do not have the Northern Kentucky Chamber of Commerce roster; chamber capture is the single most useful next step for strengthening named-operator detail across the five candidates. Second, several federal awards in Boone are place-of-performance attribution rather than awardee-headquarters — A&H Security Cabinets, a GSA-active vendor with place-of-performance Hebron, is one example, and we describe a pattern rather than naming a prime where awardee headquarters is not yet confirmed. Third, the public AS9100 cert directory at machineshop.directory is known incomplete; the IAQG OASIS authoritative directory is the source of record for any standalone cert-gap claim. Fourth, Toyota Motor North America corporate HQ moved to Plano, Texas in 2017 — only Toyota Boshoku Americas in Erlanger and the TMMK Georgetown supplier base remain in Kentucky, and candidates that lean on a Toyota corporate-services thesis have been sized accordingly.
Boone is the first saturated-suburban county we have published. Warren is manufacturing-led, Pulaski is healthcare-led, Pike is coal-transitioning. With 3,178 establishments most categories look served, so the candidate filter shifts toward credential moats — specialty cuts inside otherwise-crowded categories — rather than wide-open structural absence. We started broad across six parallel reads (aerospace and defense, the CVG cargo stack, healthcare and St. Elizabeth, schools and local government, Cincinnati spillover, and specialty saturation) and filtered to five candidates that demonstrate distinct mechanics: institutional-anchor MRO subcontracting at CVG, AS9100 cert-readiness consulting, the schools-and-fiscal-court sealed-bid sub portfolio, a high-income estate-planning boutique, and demographic-driven aging-in-place general contracting. Candidates that look promising elsewhere in Kentucky were considered and ruled out for Boone-specific reasons documented in the eliminated section.
Honest acknowledgment: the high-income suburban profile pushes the candidate pool toward credentialed and capitalized plays more than the prior three counties did. Of the five candidates, only school-facilities subcontracting and aging-in-place general contracting open clear paths for a trades operator going independent. The other three require Cincinnati-firm pedigree, FAA or AS9100 cert depth, or a capital partnership with a credentialed founder.
We have not yet reached FEAM Aero procurement, L2 Aviation supplier registration, DHL Americas Hub aviation maintenance procurement, the Safran Walton supplier-quality team, the named succession-candidate attorneys, the named pivot-candidate remodelers, Boone County Schools purchasing, the Boone County Fiscal Court procurement officer, the NKADD Council on Aging, or St. Elizabeth Care Coordination directly. Those calls are queued for the v0.2 round. Where a direct conversation would change the picture — chamber consent on naming, succession openness on named operators, MCO procurement at St. Elizabeth, the IAQG OASIS pull, the FAA Part 145 directory enumeration for Boone zip codes, or a Kentucky Secretary of State bulk pull on Boone-resident NAICS 332, 333, and 336 firms — we say so on the relevant candidate page.
