Detailed Review
Overloop is the oldest company in this category. Vincenzo Ruggiero, still CEO today, started it in 2015 as a Chrome extension called Prospect.io; it was later rebranded Overloop and is now operated by Overloop SRL, registered at Rue des Pères Blancs 4 in Brussels, running as a fully remote team.
The product is an AI-powered sales prospecting and multichannel outreach platform built around a self-reported 450M+ contact database, with automated personalized email and LinkedIn campaigns, email verification and CRM integrations for HubSpot, Salesforce and Pipedrive.
Pricing is published in three tiers: Starter at $69/user/month (250 credits/user/month, 1 email account, 3 campaigns), Growth at $99/user/month (500 credits/user/month, 3 email accounts, 10 campaigns, HubSpot and Pipedrive integration), and a custom Enterprise tier (1,000 credits/user/month, unlimited email accounts and campaigns, Salesforce integration, dedicated support). A 7-day free trial is available rather than a longer 14-day window some competitors offer.
The credit-based model means the effective cost per prospect depends on how credits are consumed, which takes more budgeting effort to compare directly against Woodpecker.co's flat per-100-prospects price or Waalaxy's flat per-user price. For a team that wants the longest-running vendor in this category with a large built-in contact database, Overloop is the most established option.
What Overloop does well
- Longest operating history in this category, running continuously since 2015
- Self-reported 450M+ contact database built into the product
- Published tiered pricing rather than a quote-only model
- CRM integrations across HubSpot, Salesforce and Pipedrive
Where Overloop falls short
- Credit-based pricing is harder to compare directly against flat per-seat or per-prospect pricing elsewhere in this category
- Only a 7-day free trial versus 14 days at several competitors
- Salesforce integration and dedicated support are reserved for the custom Enterprise tier
Standout feature. A decade of continuous operation under one founder, plus a contact database built directly into the product rather than sold as a separate data add-on.
