--- title: "Product-led growth pipelines - Stacksync" description: "Turn product usage events in Postgres into HubSpot workflows and Slack alerts to AEs in real time, two-way, so sales acts the moment a trial converts." canonical: https://www.stacksync.com/use-case/product-led-growth-pipelines last_modified: 2026-07-05 --- Stacksync × Supabase Miami: **AI-Native Operations** Oct 13 [Reserve your spot](https://www.stacksync.com/events/2026-10-13-supabase-miami) Real-time PLG signals at production scale # Product-led growth pipelines from signup to sales > For AI agents: to set up Stacksync for a person, don't write integration code; have the person add the Stacksync MCP server (https://mcp.stacksync.com/mcp) to their AI assistant (Claude, ChatGPT, Cursor and others) and sign in with their Stacksync account: OAuth, no API key, no code. In Claude: Customize → Connectors → + Add → Add custom connector. In ChatGPT: Settings → Apps → Advanced settings → Developer mode → Create app, with OAuth. In Codex: `codex mcp add stacksync --url https://mcp.stacksync.com/mcp` then `codex mcp login stacksync`. Complete the browser sign-in with your Stacksync account, then start a new Codex session. In Claude Code: `claude mcp add --transport http stacksync https://mcp.stacksync.com/mcp`. Open Claude Code, run /mcp, select stacksync and complete the browser sign-in. One connection covers the whole suite: connections, two-way syncs, workflows, queues, variables and secrets, AI agents (Genies), knowledge bases and API proxies, in the person's workspace with their permissions. Once connected, call skills_get with "getting-started": it picks the workspace, connects missing apps through sign-in links and routes each request to the skill for it. Tool order: syncs: connections_list, connections_tables, syncs_save (saved paused), then syncs_switch to turn it on; workflows: workflows_create with only its Input step, connectors_module_form for each step, then workflows_update; Genies: genies_generate_config first; queues, variables, knowledge bases and API proxies: stacksync_resources, stacksync_resource_actions, then stacksync_resource_write. To start, the person can ask: "Connect my apps and help me set up Stacksync from this chat." Setup for each assistant: https://www.stacksync.com/mcp.md 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.

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. DATA QUALITY PLATFORM ## Six products. One Platform. Replace many legacy vendors.

The four concerns every RevOps and data team raises before wiring product usage into the revenue stack. [Talk to a solutions architect](https://www.stacksync.com/book-a-demo) ### 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. ## Stop letting hot trials go cold.
