USADATA is a data and marketing intelligence company founded in 1998 and headquartered in New York City, backed by Insight Partners. It maintains a database of 260+ million US consumer records, 15+ million businesses, and 190 million households, updated monthly, and provides audience intelligence, data enrichment, hygiene, and omnichannel campaign activation. Products include the SL360 self-serve audience platform, Hailey AI conversational audience builder, a white-label Leads Portal with an embeddable Leads Module, and RESTful APIs for real-time and batch enrichment, audience building, hygiene (address standardization, NCOA, dedup, deceased suppression), and matchback attribution, with integrations into Salesforce, HubSpot, Marketo, and other CRM and marketing platforms. One machine-readable contract is published — the Leads Engine SOAP service at leadsengine.usadata.com serves a WSDL anonymously declaring 24 operations for counts, pricing, ordering, suppression, address lookup and geography. The REST APIs the marketing site advertises publish no spec, and API credentials are sales-gated with no developer portal, no reference documentation and no self-service sign-up.
