Why teams connect DealCloud and Klaviyo

Sync what happens in Klaviyo with the customer records in DealCloud, 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 Klaviyo 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 Metrics, Campaigns, Flows, Templates in Klaviyo to Investment, Relationship, Activity, Task in DealCloud with bi-directional, real-time sync. Activity and record changes in Klaviyo update the matching contact or account in DealCloud, and CRM data flows the other way wherever Klaviyo can store and use it.

Common use cases

  • 01 Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data
  • 02 Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
  • 03 Push portfolio and fund performance data from a warehouse into DealCloud so dealmakers see up-to-date metrics on each investment.
  • 04 Keep DealCloud contacts and relationships in sync with an enrichment or email platform to maintain accurate firm-wide relationship intelligence.

Common sync patterns

Owner, lifecycle stage, or account details from DealCloud sync into Klaviyo, so people working there have the context without switching tools.

Where Klaviyo runs outreach

Prospects, sends, and replies sync into DealCloud, keeping lead status current without manual imports.

Where Klaviyo supplies contact or company data

Enriched fields land directly on records in DealCloud, and refreshes keep them from going stale.
