How do you enrich a company list with revenue and headcount without ZoomInfo? (2026)

You have a CSV of company names and you need revenue and headcount on every row. ZoomInfo does this well, but entry contracts start around $15,000 a year and you usually cannot buy a small seat just to enrich one list. No free tool matches its coverage, so pick the path that fits how big your list is and how accurate the numbers must be.

For a small list you build once, go straight to the public sources the paid tools repackage. LinkedIn shows employee count ranges, SEC EDGAR has exact revenue for US public companies, and Crunchbase covers funding and employee ranges for private startups. That is free and accurate enough, but manual, and it stops scaling past a few dozen rows.

For a recurring list on a budget, Apollo and Cognism both have real free or cheap tiers far under enterprise pricing. For high coverage without a yearly contract, an AI enrichment tool that checks its own database, then the company site, then public filings for each row gets closest to the ZoomInfo result, at a cost per list instead of a contract. You describe each column in plain words and it fills them from the live web.

Whatever you use, private company revenue and headcount are estimates, ZoomInfo included, because everyone models them from the same public sources. Check a sample by hand before you trust the file.

TLDR: You do not need ZoomInfo. Pull small lists free from LinkedIn, EDGAR and Crunchbase; for scale use Apollo, Cognism or an AI enrichment tool, then verify a sample because private company numbers are estimates everywhere.
