Hull
Hull is a real-time Customer Data Platform (CDP) that unifies customer data from every source — web, product, CRM, marketing and support tools, databases and files — into a single User and Account profile using claim-based identity resolution. It ingests, computes and enriches data through a data-lifecycle pipeline (Ingest / Compute / Notify), organizes people and companies into Segments, and syncs the resulting profiles out to more than fifty tools via Connectors ("ships"). Developers integrate through a flat HTTP API at https://{organization}.hullapp.io/api/v1 covering Users, Accounts, Events, Segments, Status and Bulk operations, plus first-party Node, browser, PHP and Ruby client libraries and an outgoing/incoming webhook surface. Hull is now part of MessageBird (Bird) and is no longer accepting new customers.
Hull publishes 1 API on the APIs.io network. Tagged areas include Company, Customer Data Platform, CDP, Identity Resolution, and Data Integration.
The Hull catalog on APIs.io includes 1 event-driven AsyncAPI specification.
Hull’s developer surface includes documentation, API reference, getting-started guide, engineering blog, pricing, authentication, and 16 more developer resources.
