# Hull

> Hull is a real-time Customer Data Platform (CDP) that unifies customer data from every source into a single User and Account profile via claim-based identity resolution, then syncs enriched, segmented data out to marketing, sales and analytics tools through Connectors. Hull was acquired by MessageBird (Bird) and the platform was SHUT DOWN at 09:00 ET on 31 December 2022, with all infrastructure decommissioned and customer data deleted thereafter. The marketing site and documentation below are still served, but the API host hullapp.io no longer answers and www.hull.io presents a certificate that does not match its hostname. This profile documents the historical public developer surface; nothing here is callable. (method: generated from apis.yml + repo artifacts, verified 2026-08-13)
