Hook

Hook is a London-based software company building AI agents for customer success (CS) teams. Its platform integrates product usage, revenue, support, and sales data to build a 360-degree view of each account, then uses predictive models to forecast churn, renewals, net revenue retention (NRR), and expansion up to six months ahead. Named agents such as Echo and Activator surface account insights and automate the administrative work CS teams would otherwise do by hand, helping subscription businesses reduce churn and grow expansion revenue without adding headcount. Hook is a SaaS product used by customer success and revenue teams; it is not a public developer API, so this profile enriches company identity and security posture rather than API artifacts. Surfaced as a venture-portfolio lead and added to the API Evangelist network.

Hook is profiled on the APIs.io network. Tagged areas include Company, Customer Success, AI Agents, Churn Prediction, and Retention.

Hook’s developer surface includes support, engineering blog, and 17 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
