Clearbit is now locked inside HubSpot.
Sendburg gives you more at a lower price.
Clearbit was acquired by HubSpot in 2023. As a standalone B2B intelligence platform it no longer exists — existing plans are being migrated to HubSpot's data add-ons. Sendburg is the independent alternative with a free plan, no HubSpot dependency, and AI features Clearbit never shipped.
Why teams choose Sendburg over Clearbit
No HubSpot dependency
After HubSpot acquired Clearbit, standalone access is being discontinued. Sendburg works with any CRM or outreach tool — Salesforce, HubSpot, Pipedrive, Outreach, and more.
Buying signals and AI briefings
Sendburg includes real-time buying signals and AI company briefings that Clearbit never shipped as a product — even before the HubSpot acquisition.
Free plan and transparent pricing
Clearbit had no free plan and was expensive. Sendburg gives 1,000 verified contacts free every month with paid plans from $35/month, no annual contract.
