Why teams connect Kustomer and Lusha

Flow Lusha data into Kustomer in real time — no exports, no schedulers, no custom scripts.

Lusha is a read-only source: Stacksync reads its data in real time and delivers it into Kustomer, so Kustomer always reflects the current state of Lusha — without exports, scripts, or schedulers.

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 Lusha 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.

Common use cases

  • Enrich new CRM leads with work emails and direct dials the moment they are created.
  • Backfill missing phone numbers on an existing contact list stored in a database or warehouse.
  • Sync customers bi-directionally with the CRM and ERP so agents see deal, billing, and subscription context on the timeline
  • Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools

Where Lusha supplies contact or company data

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

Where Lusha can store CRM context: fields kept current

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

Where Lusha runs outreach

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

What you can sync between Kustomer and Lusha

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Kustomer objects Lusha objects
Users Agent records map conversation ownership to people in other systems. Company Profiles Firmographic records (industry, size, location) appended to account or company rows.
Teams Team assignments support routing parity and reporting. Email Addresses Work emails written into CRM contact fields during enrichment.
Tags Labels on conversations and customers sync for categorization and analytics. Phone Numbers Direct-dial and mobile numbers appended for outbound calling workflows.
Notes Internal annotations carry context alongside synced conversations. Prospecting Results Search-based lists of people and companies matching filters, used to seed lead lists.
Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. Bulk Enrichment Requests Batch lookups that enrich multiple records per request, used to backfill large contact lists rather than one-off calls.
Conversations Support threads across channels sync outward for analytics and CRM context. Person Profiles Contact-level enrichment results (work emails, phone numbers, title, company) returned per lookup.
