Knock2 is a website visitor identification platform that identifies the exact people and companies visiting your website. When someone visits your site, Knock2 identifies the visitor, enriches that record with up to date contact details, and scores it against your Ideal Customer Profile using configurable, AI-assisted rules. This way, reps can prioritize outreach on contacts already sitting in their HubSpot pipeline.

Knock2 also logs buying-signal context — page visits, intent signals, deal-relevant activity — directly as notes on the HubSpot record, giving reps context without leaving HubSpot. Plays let revenue teams define exactly which visitors are worth syncing, so only qualified, high-intent leads reach HubSpot, keeping the CRM free of noise instead of flooding it with every anonymous hit. The result: your HubSpot pipeline reflects real buying intent as it happens, and a rep can act on a hot lead within minutes of a site visit.
