Reverse ETL

ELT vs. reverse ETL: HubSpot and Amazon S3

ELT (Extract, Load, Transform) moves data from HubSpot into Amazon S3 for analysis. This is the approach shown on this page, and the one to use for dashboards, reports, and data models.

Reverse ETL works the other direction: it pushes enriched data from Amazon S3 back into HubSpot. For example, you could sync computed lead scores or customer segments from your warehouse into HubSpot to personalize outreach.

Weld supports both directions, so you can build a complete data loop between HubSpot and Amazon S3.

Amazon S3 to HubSpot
Incremental syncing
Weld uses incremental syncing where supported by the HubSpot API, loading only new and updated records to minimize data transfer and warehouse costs.
Schema handling
Weld automatically manages schema changes. If HubSpot adds new fields, they're detected and added to the corresponding Amazon S3 tables.
Data freshness
Sync frequency depends on your Weld plan. Most connectors support schedules from every 5 minutes up to daily intervals.
Security
All data is encrypted in transit (TLS) and at rest. Weld is SOC 2 Type II compliant and supports IP whitelisting for database connections.
