Product-led growth pipelines
from signup to sales

Stream product usage events from Postgres into HubSpot the instant they fire, route Slack alerts to the right AE, and write activity back two-way so sales never works a cold lead.

Where PLG handoffs break in production

Three reasons usage signals never reach sales.

PLG only works if product data lands in the CRM while the user is still hot. The handoff from app to revenue stack is where it stalls.

01 - Stale syncs

The trial converts, the AE finds out tomorrow

Most reverse-ETL flushes Postgres to HubSpot on an hourly or nightly job. The buyer hits the 'aha' moment and the AE sees it a day late, after the intent has cooled.

LATENCY
02 - One-way push

Sales notes never make it back to product

Reverse-ETL pushes usage into HubSpot but the AE's call notes and deal stage never flow back to your data model. Product scoring and sales context drift apart by the week.

CONFLICT POLICY
03 - Noisy alerts

Slack drowns in low-signal pings

Naive triggers fire a Slack alert on every event, so AEs mute the channel. Without thresholds and dedup on the Postgres stream, the signal that matters gets buried.

How fast does a usage event reach HubSpot?

Sub-second when Postgres logical replication or CDC is enabled, otherwise 1–60s on a configurable poll. The AE gets the Slack alert while the user is still in the product.

Can sales activity flow back into our database?

Yes. Sync is two-way, so HubSpot deal stage, owner, and call notes write back to Postgres with field-level conflict policies, keeping product scoring and CRM in step.

How do we avoid alert fatigue in Slack?

Set thresholds, dedup keys, and conditions on the event stream so only qualifying signals fire. A single user's repeated events collapse into one alert, not fifty.

Can we map our own event and scoring fields?

Yes. Custom Postgres columns, JSON event payloads, and HubSpot custom properties map in the visual mapper alongside standard fields and sync the same way.
