What it is and who it's for

This is a real-time B2B contact search engine built for outbound sales teams that need to assemble prospect lists fast. Instead of serving a frozen database snapshot, it runs a live lookup and re-verifies contact details at search time, then pushes them into your CRM. The sweet spot is US-focused SMB and mid-market reps doing high-volume cold outreach who want emails and direct dials without leaving LinkedIn.

Strengths and weaknesses

The database is enormous, advertised at 1.7B+ contacts and 150M+ companies, so coverage of US prospects is rarely the problem, and the Chrome extension that pulls data straight from LinkedIn is the feature reps consistently praise. Integration breadth helps too, with one-click export to Salesforce, HubSpot, Outreach and Salesloft. The weaknesses are real, though: bounce rates of 20-30% are widely reported despite marketed accuracy claims, you spend credits even on bad records, and unexpected auto-renewals plus a 60-day cancellation notice are the loudest complaints across G2, Capterra and Trustpilot.

Pricing and value

Pricing is deliberately opaque. The only publicly listed paid tier is Basic at roughly $147/mo billed annually for 250 monthly credits; Pro and Enterprise are quote-only, usually with a multi-seat minimum and reported per-seat costs anywhere from about $79 to $299. Everything is credit-metered, intent and automation add-ons stack on top, and the headline number can understate true cost once you factor in wasted credits on bounced records. Run the free 50 credits and a short paid pilot before signing anything annual.

Regional fit and verdict

It's a global SaaS, usable worldwide, and the company says it can transfer data in line with major privacy regulations when required, but coverage and verification skew heavily toward North America. It offers none of the firm contractual compliance guarantees that data-compliance specialists like Cognism market, so for strict-consent prospecting the lawful basis, consent and suppression-list handling sit largely on you. Net: for a US-centric team that lives in LinkedIn it's a fast, well-integrated prospecting engine, but verify accuracy on your own ICP during the trial and read the renewal terms in full before committing to anything annual.
