For SDR teams on Close, SyncGTM automates the enrichment-to-outreach pipeline. New leads are enriched automatically, and the workflow builder can trigger Close sequences based on enrichment results — like routing leads with verified phone numbers to calling queues.

At $49/mo with a free tier, Apollo is the most cost-effective enrichment option for Close teams that want prospecting and data in one platform.

Lusha is the SDR favorite for Close CRM enrichment. Its verified direct dials power Close's built-in dialer — look up a prospect on LinkedIn, grab their phone number with Lusha's Chrome extension, and push it to Close for immediate calling. The workflow takes seconds.
