Hook builds AI agents for Customer Success teams, focused on reducing manual admin and helping teams prioritise accounts and actions. The Hook product connects to customer touchpoints like product usage and conversations, then surfaces insights and next steps for renewals, expansion, and churn risk. Hook sells primarily to B2B subscription and enterprise businesses that want to grow revenue from existing customers. Hook is headquartered in the City of London and markets the platform as a predictive revenue growth tool for CS organisations.

Hook is based in London, with an office at 21 Great Winchester Street near Liverpool Street. Hook runs a hybrid setup with set in-office days for the whole team, and roles that specify multiple days per week in the office alongside flexible working outside those days.
