Looking for a ZoomInfo alternative — or weighing ZoomInfo vs Company Dossier? Here's a fair, accurate read on what each tool does best, so you can pick the right one. Company Dossier is free, built from public sources, and every claim is sourced.
ZoomInfo is a sales-focused B2B intelligence platform built around contact and company data. Its core value is reach: phone numbers, email addresses, org charts and intent signals for go-to-market teams. Sales and marketing orgs use it to build target lists, enrich their CRM and find the right person to call.
ZoomInfo is a paid, enterprise-priced platform. Its contact database and workflow tools are sold by seat and tier. It's a strong tool for what it's built to do — and that focus is exactly what makes a comparison useful, because Company Dossier is built for a different job.
A general, honest comparison — no invented prices, no straw men.

For those jobs, a paid, purpose-built platform is the right call and Company Dossier is not a substitute. We'd rather tell you that than pretend otherwise.
Company Dossier is a fast first-pass intelligence file — free, public-source, fully attributed, and readable in one place. It fits better when:
It's not a contact database and not a replacement for curated paid datasets. It's the step you take first: open a free, sourced file on a company, read its whole story in minutes — overview, people, hiring, money, locations, tech, news, relationships and risk — and decide from there whether deeper paid tools are worth it. And it runs wherever you work: the web app, the VS Code extension, the npm CLI, and inside ChatGPT and Claude.
Yes — for company research. Company Dossier is free and assembles a sourced profile of any company from public data. It is not a contact database, so it won't hand you bulk emails or phone numbers; it gives you context to research a company well.
No. It deliberately uses public sources only and is not a contact or lead database. It surfaces leadership and org structure from the public record, not personal contact data.
Use ZoomInfo to reach people; use Company Dossier to understand the company first — its money trail, hiring, tech and risk — so your outreach lands with context.
