Why teams connect Slack and Twenty CRM

Sync what happens in Slack with the customer records in Twenty CRM, in real time and in both directions.

The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Slack holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.

Stacksync connects Channels, Messages, Threads, Users in Slack to Workspace Members, People, Companies, Opportunities in Twenty CRM with bi-directional, real-time sync. Activity and record changes in Slack update the matching contact or account in Twenty CRM, and CRM data flows the other way wherever Slack can store and use it.

Common use cases

  • Archive channel messages into a warehouse or database for compliance and analytics
  • Create or update records in a database when specific messages or reactions occur in a channel
  • Mirror support tickets or tasks between Twenty and an operations tool.
  • Run a continuous sync from a legacy CRM into Twenty during a migration so both systems stay usable through cutover.
