Who Owns This Brand? is an ownership research platform operated by 37x Limited (37X Ventures), a Guernsey-registered company. It helps users trace more than 30,000 global brands to the companies named as their owners, with evidence, dates and confidence labels attached to each relationship. Users can search brands, owners or companies, browse an A–Z directory, explore company portfolios, compare businesses, and investigate connections across ownership records. The site also offers category browsing, a legal identity explorer and research questions linking brand ownership with subjects such as government spending, consumer choice and product safety.

Its evidence-led approach distinguishes official, corroborated, source-claimed and candidate relationships, while making unresolved gaps visible. Sources include public brand identity data, company pages and official registers; legal-entity information from GLEIF and company registers can strengthen matches, while private catalogue signals are used only to discover aliases and do not affect ownership confidence. The platform cautions that licences and packaging declarations do not by themselves establish ownership.
