Best Company Databases in 2026

Finding businesses for sales or research starts with understanding what information a company database makes available and how you can work with it. Compared on company records, advanced filters, technographic data, and intent signals, these options also list API access and monthly export limits. Free-plan availability and paid-from pricing can help frame access choices. Landbase B2B Database, Wappalyzer, and BuiltWith are among the entries shown, alongside Enigma and OpenCorporates. Consider what kinds of company information your work calls for, whether you need to filter or export records, and how you expect to use the data.
