HubSpot Runs Clay Across a 60-Million-Contact CRM. The Lesson Isn't the Scale — It's the Discipline.

Clay published an interview with Faris Sumadi of HubSpot’s demand management team describing how HubSpot uses Clay to manage enrichment across a CRM holding roughly 30 million companies and 60 million contacts, with thousands of new inbound contacts arriving daily. Sumadi describes Clay as an orchestration layer beneath HubSpot’s CRM that removes real bottlenecks: teams can test new enrichment workflows without pulling in engineering, multiple vendor contracts consolidate into a single gateway, and legal can approve data experiments faster because the data stays inside Clay rather than touching HubSpot’s core systems. The interview distills to five operating rules: enrich data once so the whole org works from consistent records; build reusable functions instead of letting teams duplicate workflow builds; track ROI by monitoring which enriched contacts actually get worked rather than raw enrichment volume; curate views so reps see only relevant fields instead of drowning in 1,034-plus contact properties; and design qualification logic around how reps actually work, not a theoretical scoring formula. Sumadi’s summary of the hidden benefit: “we basically should be enriching our entire CRM” so every team operates from current data.

The scale HubSpot is running Clay at lines up with where Clay itself says it’s headed. CEO Kareem Amin’s July roadmap announcement — a “Summer of Launches” spanning 12 releases in 12 weeks — frames GTM as moving through three eras: a past data era, a present infrastructure era, and an emerging “learning loops” era where agents autonomously refine plays over time. The releases back that framing directly: Audiences, a centralized data layer supporting continuous-refresh search across 15 million-plus records, and an Account Research Agent that converts unstructured signals into structured CRM fields. HubSpot’s five operating lessons are, in effect, what it looks like to run that infrastructure-era platform in production at real scale rather than in a product demo — the discipline of enriching once and tracking usage, not the record count, is the transferable part for any team running Clay at a fraction of HubSpot’s size.
