Our verdict: Clearbit instead of SimilarWeb?

Switch if: B2B firmographic enrichment and identifying which companies are visiting your own site, now delivered inside HubSpot as Breeze Intelligence.

Don’t switch if: Estimating a competitor's traffic, channels, keywords or ad spend, because it enriches CRM records rather than benchmarking websites.

Biggest caveat: Since HubSpot's December 2024 acquisition, standalone signup was removed and free tools sunset, and contact-level data draws recurring stale/duplicative-data complaints.

What Real Users Complain About

Negative feedback found on public platforms — because every tool has trade-offs, and vendors won't show you these.

lots of inaccuracies and duplicative data

Sales intelligence is very overhyped overall, but Breeze/Clearbit won't save you.
