With one click, reps can export contact records and instantly route clean, enriched data to Salesforce, HubSpot, Outreach, Salesloft, and beyond—no spreadsheets, no portals, no extra steps.

Instead of locking data behind bloated systems, it puts the workflow where reps already work—on LinkedIn—and gives RevOps full control over how data enters the funnel. Our Chrome extension supports unlimited exporting, real-time enrichment for mobile numbers and verified emails, and native integrations that don’t require IT involvement. The result: more coverage, faster adoption, cleaner data, and significantly lower costs.
