Integrations
Works with the tools you already use.
Connect Salesforce or HubSpot, import a CSV, get notifications in Slack, and reach your overlaps from your own tools through the MCP server and the REST API.
What you can connect.
- Salesforce
Connect your Salesforce over OAuth. Accounts sync into your own workspace and are matched to a partner's on their domain. The connection token is encrypted at rest.
- HubSpot
Connect your HubSpot over OAuth and it works the same way: accounts sync into your workspace, matched on domain, with the token encrypted at rest.
- CSV import
No native connector for your CRM yet? Import a CSV. A row with no usable domain is rejected with the row flagged, rather than quietly accepted and left to produce a false match later.
- Slack
Connect your Slack workspace to receive notifications. Slack asks the same sharing layer as the web app.
- MCP server
Bring overlaps into the AI assistants your team already uses. A workspace member connects an assistant through OAuth, and the same sharing rules apply on every call.
Read the developer guide - REST API
Create a key, exchange it for a token and make your first call. The same sharing rules apply on every call, and the guide states every current limit plainly.
Read the developer guide
One set of sharing rules, everywhere.
The web app, Slack, the AI agent, the MCP server and CRM writeback all ask the same server-side layer what a partner may see.
