We use OpenCorporates to answer two questions that come up constantly in supply-chain work: does this company really exist, and who actually owns it? It is the registry layer of our ownership-tracing and supplier-verification tools, and often the only structured source that reaches the small, private companies we look into. We also use it to check ownership claims in our public-interest research on critical-infrastructure chokepoints.
This note describes what we are building, walks through real lookups from our supplier work and our infrastructure research, and sets out how we handle the data.
Watchman's Tower builds its own research tooling for supply-chain transparency and corporate ownership tracing. Each tool is small and does one job, usually wrapping a single open data source. The tools are then combined into repeatable research workflows, and every finding they produce cites the record it came from.
Walks a company up its ownership chain, starting with free and open sources: Wikidata, GLEIF, OpenCorporates, then web research. Each link is labelled as confirmed or unresolved. We never guess a parent company to fill a gap.
Finds manufacturers and distributors for specialty ingredients, then checks that each candidate is a real, active, registered company before anyone requests a quote.
In development. Looks for local contractors and service firms and checks their business standing before we hire them. Registry records confirm a business is registered and active under the name it trades as.
Linchpins, our library of more than 120 investigations into hidden single points of failure: the one plant, supplier or owner a whole system depends on. Registry data is how we check who really controls each chokepoint.
Name → registry record (search), full company record with officers and home company (company), and beneficial-ownership control statements (control) in jurisdictions that publish them.
QuestionSozio, a long-established fragrance manufacturer and a supplier to a venture we support, is privately held. We wanted to know which group controls it.
Other sourcesWikidata found nothing relevant. GLEIF returned five unrelated Italian and French entities.
OpenCorporatessearch found the correct US legal entity, Sozio, Inc. (New Jersey), but its record carries registration details only. control turned up the structured ownership link: Companies House records Sozio UK Limited as 75–100% owned by the French parent Sozio SA.
ResultWith that UK link in hand, web research identified the ultimate parent as a French family-owned holding group. We cross-checked the controlling individual on the UK register against the group's own published statements, and they matched. The only structured, registry-grade evidence in the chain came from OpenCorporates.
QuestionVigon International, a Pennsylvania flavor and fragrance ingredient distributor, is a current supplier. We wanted to confirm which legal entity we deal with today and who stands behind it.
OpenCorporatessearch returned seven registrations under the name across New Jersey, Pennsylvania, Arizona, Florida and the UK. The active Pennsylvania company, Vigon International, LLC, lists Azelis Americas, LLC on its record. The original 1988 New Jersey corporation still appears as a Pennsylvania foreign registration.
ResultThis matches the public record: Azelis, a global specialty-chemical distributor, completed its acquisition of Vigon in June 2021. Our supplier sits inside a large multinational group, not an independent family firm, so decisions about its supply, pricing and terms are now made at group level.
LessonNames are not identities. A control search for "Vigon" returned six UK companies, and five of them have nothing to do with the supplier. The Arizona registration is a separate, now-inactive 2021 corporation with no apparent connection. Checking jurisdiction, address and incorporation date is what keeps a lookup honest.
QuestionA search for sources of a rare fragrance aroma chemical surfaced Bedoukian Research as a possible custom-synthesis manufacturer. Before contacting any candidate, we confirm it is a real operating business and not just a catalog listing or reseller.
OpenCorporatesBedoukian Research, Inc. has been an active Connecticut corporation since 1972, headquartered in Danbury. It holds current foreign registrations in California, Florida, Oklahoma and Pennsylvania, and has affiliated companies in Switzerland and Singapore (2021).
ResultThe registry shows a five-decade operating history and a growing international footprint. That backed our recommendation to approach Bedoukian for a quote. No control statements exist, because US state registries do not publish beneficial ownership. We record that as a coverage gap, not as a finding.
QuestionLMR Naturals, a natural-ingredients house in Grasse, France, is another supplier. Who is the legal counterparty behind the brand?
OpenCorporatesSearching the brand name returns nothing, but its legal name does. Both French entities of Laboratoire Monique Rémy (1983 and 1993) are recorded as cessée (ceased). An active French entity of International Flavors & Fragrances is registered in Grasse.
ResultThis agrees with the public record: IFF acquired LMR in 2000. The brand lives on, but the contracting entity is IFF. French registry data on OpenCorporates carries no control statements, so the ownership link itself rests on published sources, and we cite it that way.
Our Linchpins library has more than 120 investigations into single points of failure in critical supply chains: the one plant, one supplier or one owner that a whole system quietly depends on. Many of those findings turn on one claim, that a single company controls a chokepoint. We use OpenCorporates to check those claims against the official registers instead of relying on company marketing and press coverage.
ClaimOur sterilization investigation found that a single company, Sotera Health, controls the largest ethylene-oxide sterilization network (Sterigenics), a dominant supply of Cobalt-60 for gamma sterilization (Nordion), and the lab that validates both methods (Nelson Labs). That evidence came from Sotera's own investor materials.
OpenCorporatesThe UK beneficial-ownership record for Sterigenics UK Limited names Sotera Health Company as the entity with significant control, notified in May 2024. Earlier statements, notified in 2016, point back to the business's private-equity ownership before Sotera's 2020 IPO.
ResultThe integration claim now rests on a statutory filing as well as the company's own marketing, and the register shows the ownership history too. The 2016 statements carry no cessation date, so we treat them as historical rather than current. Beneficial-ownership records reflect what was notified, and they are not always tidied afterwards.
ClaimOur parking-infrastructure investigation found that FAAC, an Italian group, owns much of the gate, barrier and payment hardware in parking garages across North America. It described FAAC as a conglomerate most people have never heard of, but it did not answer who owns FAAC.
OpenCorporatesControl statements for FAAC Entrance Solutions UK Limited record FAAC S.p.A. as its 75–100% owner. Alongside it, three individuals hold control jointly. Public reporting identifies them as the trustees of the trust that governs FAAC for its sole shareholder, the Archdiocese of Bologna, which inherited the company and has held 100% of it since 2015. The same record shows the UK business was held by ASSA ABLOY Entrance Systems in April 2020 and passed to FAAC with a notification date of 31 August 2020.
ResultThat date matches ASSA ABLOY's own announcement: it sold the business to FAAC as a divestiture required by the European Commission to clear ASSA ABLOY's acquisition of agta record, deconsolidated "as of August 31, 2020." Here the register exposed a governance layer the investigation had missed, and it dated a competition-remedy transfer to the exact day.
ClaimOur wastewater investigation found that the polyacrylamide polymers used to dewater municipal sludge come overwhelmingly from one French company, SNF. One plant operator we cited put it this way: the market is "so incestuous it's hard to know" who actually makes what.
OpenCorporatesSNF (UK) Limited is recorded as owned by the French parent SNF Group. It in turn holds several UK subsidiaries, and some of their names give no hint of SNF. Among them are Goldcrest Chemicals, a UK chemical company incorporated in 1978, and Rheolab, both now dissolved.
ResultThis is company-level evidence for the pattern the investigation described: formerly independent names absorbed into one group. It is also a reminder about name matching. A search for "SNF" in the Louisiana register, where SNF runs a major US plant, returns mostly unrelated skilled-nursing-facility companies.
