Overloop
AI sales prospecting: a 450M+ B2B contact database, buying signals and AI-drafted email and LinkedIn sequences, from $69/user/mo.
From $69/user/mo 7-day free trial API
Bottom line
Overloop is an AI sales prospecting platform: it builds lead lists from a 450M+ contact database, spots buying signals, drafts personal first messages and runs email plus LinkedIn sequences. Starter is $69 per user a month and Growth, which adds CRM sync and the API, is $99. For recruiters it fits agency business development rather than candidate sourcing.
Stands out for: It puts the contact database, buying signals, AI message drafting and email plus LinkedIn sequencing in one seat, so an agency desk can find hiring companies and reach the decision maker without stitching a data tool to a sequencer. Messages wait for your approval before anything goes out.
Watch out for: Credits are tight at 250 a month on Starter and 500 on Growth, and a phone number costs 5 of them. CRM sync is gated: none on Starter, HubSpot and Pipedrive on Growth, Salesforce only on Enterprise. Overloop was acquired by Sortlist, an agency marketplace, and still runs an older Classic app beside the new Overloop AI app.
Overview
Overloop finds prospects that fit your business, gets their contact details and writes outreach around what is happening at each company. You start from your website, review the suggested audience, connect an email or LinkedIn account and approve the messages and timing before a campaign launches.
Lists come from a built-in database of more than 450 million B2B contacts, filtered by role, industry, location and company size. Buying signals such as a new executive, a hiring push or a funding round show who to contact now, and the AI drafts a first message that ties your offer to that change. It also drafts replies in the shared inbox for you to edit and send.
Campaigns mix email and LinkedIn steps in one sequence, with conditions such as sending a LinkedIn message only when the prospect is already connected, and follow-ups that stop when someone replies. Email verification runs before sending, and a phone finder searches several sources and charges credits only when it finds a number.
Pricing is per user: Starter at $69 a month with 250 credits and Growth at $99 with 500 credits, the HubSpot and Pipedrive integrations and a REST API. Enterprise adds Salesforce and a dedicated IP. Overloop is based in Brussels, has been on the market since 2014 and was acquired by the agency marketplace Sortlist.
