How it works
HubSpot exposes a comprehensive REST API plus a robust webhook system. We support both direct API integration and Zapier-mediated flows. The most common deployment: a Zapier watch on /api/v1 signal updates writes engineering-momentum custom properties to HubSpot company records, which feed standard HubSpot workflows. For Pro+ accounts, direct webhook integration removes the Zapier middleman.
Live workflows
Lead enrichment
When a HubSpot contact's company shows up in the GitDealFlow signal panel, a workflow auto-tags the contact with the current engineering momentum tier (accelerating / steady / decelerating).
Deal-stage progression triggers
A HubSpot workflow watches for engineering acceleration breaks on companies in active deals, when a portfolio company crosses the +50% commit-velocity threshold, the deal stage advances automatically.
Sequence personalization
HubSpot Sequences pull in the latest signal snippet for each prospect ('your engineering org shipped 87 commits this week, up 41% from prior month') as a personalization token.
What's not yet available
There is no first-party HubSpot Marketplace app yet. The Zapier path covers most B2B SaaS use cases; the App Marketplace listing is roadmapped once we accumulate enough HubSpot-paying customers to justify the certification effort.
