Knock2 identifies the anonymous companies and people visiting your website, scores them against your ICP, and routes qualified leads into your HubSpot CRM — automatically.

With the Knock2 + HubSpot integration you can:

1. In the Knock2 dashboard, open the App Marketplace. Find HubSpot in the CRM category and select it.

2. Click Connect.

3. You'll be redirected to HubSpot to sign in (if you aren't already) and review the requested permissions.

4. Click Connect app on the HubSpot side. You'll be redirected back to Knock2. Return to the App Marketplace to confirm the integration shows as connected.

What this step does and doesn't do: Connecting HubSpot in the App Marketplace does not by itself write any data to your HubSpot instance — it only reads data (contacts, companies, deals, owners) needed to match and score your existing records. Writing data to HubSpot happens only when you configure a Play to send to HubSpot — see Use the app below.

After connecting, finish a couple of one-time settings:

1. Select a Sales Pipeline. Knock2 needs to know which HubSpot deal pipeline to read from and write deal-stage updates to. Go to Settings → Integrations → HubSpot and choose your pipeline from the dropdown.

2. Field mapping (optional). If you use custom HubSpot properties for firmographic or scoring data, map them under Settings → Integrations → HubSpot → Field Mapping so Knock2 writes ICP scores and enrichment data to the properties your team already uses instead of creating new ones.

3. Sync direction. By default, Knock2 reads Contacts, Companies, Deals, and Owners from HubSpot to avoid creating duplicates, and writes back Contacts, Companies, and Deal stage/property updates only through Plays you explicitly configure (see below). There is no global "sync everything" toggle — sync only happens where a Play is configured to send to HubSpot.

Once connected and configured, Knock2 works two ways:

Automatically, through Plays. Build a Play with HubSpot as a destination. For example, a Play that filters for qualified, high-ICP-score contacts can automatically:

On the HubSpot side. Once a record syncs, your reps see Knock2 data directly on the familiar HubSpot Contact/Company/Deal record — no separate tool to check.

To disconnect Knock2 from HubSpot:

1. Go to Settings → Integrations → HubSpot.

2. Click Disconnect.

What disconnecting does and doesn't do: Disconnecting stops all future reads from and writes to HubSpot immediately. It does not delete or roll back any data Knock2 already wrote to your HubSpot contacts, companies, deals, or notes — those records remain in HubSpot as they were at the moment of disconnection. Plays that had HubSpot configured as a destination will stop delivering to HubSpot until you reconnect and reselect a destination.

Uninstalling removes the Knock2 app entirely from your HubSpot account (in addition to disconnecting it from Knock2's side).

1. In HubSpot, go to Settings → Integrations → Connected Apps.

2. Find Knock2 and click Uninstall. (See HubSpot's own Knowledge Base article on managing connected apps for the current HubSpot-side steps, since that flow lives entirely in HubSpot's UI.)

Data consequences: Uninstalling revokes Knock2's OAuth access immediately — Knock2 can no longer read from or write to your HubSpot account. As with disconnecting, previously-synced data already written to HubSpot (contacts, companies, deals, notes) is not deleted or reverted; it remains in your HubSpot portal under your ownership. Data Knock2 holds internally (identified visitors, ICP scores, Play history) is retained in Knock2 per your Knock2 account's normal data retention — uninstalling the HubSpot app does not delete your Knock2 account or its data.
