Hook

Hook is a platform of AI agents, named Echo and Activator on its site, that monitor customer calls, meetings, support tickets, product usage and external signals. It flags churn and expansion risk, suggests next-best actions, and can trigger follow-ups via Slack, email or CRM.

The product is sold to customer success teams and their leaders at B2B companies, with pricing and contract terms not stated on the website. The site describes an onboarding process of about four weeks, from importing books of business to adding ML health scores and automated workflows. Case studies cite GWI and hackajob.

Hook is headquartered in London, with its office on Great Winchester Street, and the careers page lists open roles in Commercial, Customer Success and Engineering, all based in London. The site states SOC 2 Attested and ISO 27001 Certified status and says the company offers equity to all employees and is backed by early-stage investors.
