HubSpot has evolved from a marketing automation tool into a full Revenue Operations platform, and its ecosystem of native integrations has grown to match. For RevOps teams running HubSpot as their CRM, the best-fit tools are those with certified HubSpot integrations — bidirectional sync, native contact/deal association, and workflow triggers that fire without Zapier.
This directory curates the top tools across the HubSpot ecosystem: sales engagement platforms with certified HubSpot integrations (Apollo, Lemlist, Klenty), conversation intelligence tools (Gong, Jiminny), customer success platforms (Gainsight for HubSpot, ChurnZero), and data enrichment tools that write directly to HubSpot contact properties (Clearbit, Apollo).
Each tool profile includes a Stack Fit section that describes how data flows into and out of HubSpot, whether the integration is bidirectional, and what HubSpot tier (Starter, Pro, Enterprise) is required for the integration to work.
