Overloop

What is Overloop?

Overloop is a sales prospecting and engagement tool designed to help teams identify B2B prospects, build targeted lists, and manage personalized outbound communication. It combines prospect data, email verification, AI-assisted message creation, email and LinkedIn workflows, campaign automation, tracking, and reporting. Users can define ideal customer profiles, review prospects, configure outreach sequences, and connect supported CRM systems. Its approach centers on repeatable, reviewable outbound workflows rather than replacing a company’s primary CRM.

Overloop provides access to a B2B database of 450M+ contacts and supports email verification, AI-assisted prospecting, and multichannel campaigns. Its plans start at $69 per user, with 250 credits on Starter and 500 on Growth. Growth costs $99 and supports 3 email accounts and 10 campaigns. Enterprise includes 1,000 credits, unlimited email accounts and campaigns, and Salesforce integration. Overloop also offers a 7-day free trial, reporting, email warmup, LinkedIn workflows, CRM connections, and integrations with Slack, Calendly, Zapier, HubSpot, and Pipedrive.
