Why teams connect HubSpot and Lusha

Flow Lusha data into HubSpot 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 HubSpot, so HubSpot 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

  • 01 Backfill missing phone numbers on an existing contact list stored in a database or warehouse.
  • 02 Append firmographic company data to account records before territory or scoring runs.
  • 03 Write warehouse-computed lead and account scores back to HubSpot properties on a schedule or in near real time.
  • 04 Sync HubSpot Tickets with an internal support database to unify service reporting across channels.

Common sync patterns

Where Lusha runs outreach

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

Where Lusha supplies contact or company data

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

Where Lusha can store CRM context: fields kept current

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

What you can sync between HubSpot and Lusha

How changes propagate between HubSpot and Lusha

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

HubSpot Lusha Sub-second propagation

DetectionHubSpot pushes changes as they happen — webhook events backed by change data capture. Records: incremental near-real-time change tracking.

DeliveryLusha does not accept inbound record writes, so this direction carries requests rather than records: Lusha's output flows back as field updates on the originating HubSpot records.

Lusha HubSpot Interval-based propagation

DetectionStacksync polls Lusha for changes on an incremental schedule, reading only records changed since the previous pass. Data is fetched on demand per lookup, so syncs poll or trigger enrichment when source records change.

DeliveryEach detected change is written to HubSpot through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • HubSpot: Request limits vary by subscription tier and API type.
  • Lusha: Lookups consume credits and are subject to the platform's API rate limits.
