About

What is Cognism

Cognism pulls verified contact and company data from multiple vendors, refreshes it on a 30-day cycle, and delivers it via a web app, API, or bulk export. It's built for SDR and BDR teams, RevOps, and GTM leads at mid-market and enterprise companies who need accurate mobile numbers and emails before they pick up the phone or hit send. The standout capability is phone-verified mobile data — numbers are checked against live carrier records, not just scraped and stored — which meaningfully reduces the dead-number problem that plagues most prospecting databases. Intent signals layer on top, letting teams prioritize accounts showing active buying behavior rather than working a flat list. Pricing is custom and contact-sales only, so smaller teams or early-stage companies without procurement bandwidth will find the buying process slow and the cost hard to forecast.

Our verdict

Vanderbuild take

Cognism is a serious prospecting database and enrichment layer for SDR/BDR teams and RevOps at mid-market and enterprise scale — if your team is burning time on bad mobile numbers or stale CRM records, this is the category of tool that addresses it directly. On the agentic side, the REST API is available and documented, meaning you can wrap Cognism's data into your own MCP layer or agent orchestration stack without too much friction — it's capable, though MCP-native status is unconfirmed, so you'll be doing that plumbing yourself. Budget-wise, this is enterprise-priced with a contact-sales-only model, so expect procurement involvement and a negotiation cycle before you're live. The honest limitation: coverage and data freshness vary by region, and teams prospecting heavily outside North America and Western Europe may find hit rates lower than expected — worth running a sample test against your ICP before committing.
