StackTie builds and maintains custom HubSpot integrations for revenue teams. We connect HubSpot to the rest of your stack: billing systems like Stripe, product and usage data, warehouses like Snowflake and BigQuery, support tools, and internal apps. The result is a CRM that stops drifting, a team that stops copy-pasting between tabs, and a forecast that matches what actually happened. Two things set us apart. HubSpot is all we do, and we build products rather than one-offs. We publish and maintain our own apps on the HubSpot App Marketplace (IssueLinker and NoteLinker), so your integration stands on code that already passed HubSpot's review and runs in production. We also do not disappear at delivery. Every build includes a monthly maintenance retainer, so when an API changes or a sync breaks, someone is already accountable. Fixed scope, fixed fee, and one point of contact throughout. Live in 14 days or your money back, deposit included.
