ZoomInfo
B2B contact database and sales intelligence platform providing company and contact information, intent data, and sales automation for lead generation.
The problem it solves: I need verified contacts, org charts, and technographic data on target companies to fuel my B2B sales outreach.
Our verdict: ZoomInfo instead of SimilarWeb?
Switch if: B2B sales and marketing teams that need company and contact data, technographics and buyer intent for outbound, not web-traffic analytics.
Don’t switch if: Marketers or analysts who want to estimate any website's traffic, channels, keywords, ads or app metrics; ZoomInfo is a contact database, not a traffic tool.
Biggest caveat: Multi-year contracts with auto-renewal clauses requiring 60-90 days written notice, 10-30% renewal price hikes, and real-world contact accuracy that users repeatedly put around 60-77%.

What Real Users Complain About
Negative feedback found on public platforms — because every tool has trade-offs, and vendors won't show you these.
“We canceled subscription as per contract and they keep sending invoices, statements and now collection agencies even if we call them and write to them.”
“Multi-year subscriber here. I don't recommend investing in ZoomInfo products unless you can get a deep discount. The contact information is about 60% accurate.”
“Apparently ZoomInfo includes a sneaky auto renewal clause in their contract that was never mentioned in sales conversations and they seem to be railroading us into renewing another year against our will.”
