Overloop
AI Sales Prospecting Platform
Overloop is a sales prospecting platform that combines a B2B contact database with AI-assisted email and LinkedIn outreach. Users define an ideal customer profile to build prospect lists, then run multichannel campaigns through reviewable workflows, keeping human review in the loop while AI prepares repetitive research and messaging.
Core capabilities include a database of 450M+ B2B contacts, email verification, buying signals (job changes, funding, engagement), a phone number finder that searches a waterfall of sources, and coordinated email and LinkedIn sequences with delays and conditions. Outreach features cover AI-drafted personalized messages, email warmup and deliverability controls, and tracking of opens, clicks, replies, bounces, and out-of-office replies. A Chrome extension supports list building, and integrations include Slack, Zapier, HubSpot, Pipedrive, Salesforce, and a REST API.
Overloop is aimed at sales teams, founders, and agencies running outbound prospecting. It is packaged as seat-based plans with monthly prospecting credits: a Starter tier for individuals, a Growth tier for growing teams with additional integrations, and a custom-priced Enterprise tier for large teams. A free trial and a free starting option are available, with plan limits on email accounts, campaigns, and integrations.
