Best Clearbit Alternatives

Yes. HubSpot acquired Clearbit in December 2023, according to Clearbit's own blog post of February 13, 2025, which also says the Clearbit team has fully integrated into HubSpot. Clearbit's enrichment, buyer intent and form shortening became Breeze Intelligence, and HubSpot's product page now calls the capability data enrichment. So the answer to Clearbit vs HubSpot is short: they are the same data, sold only as part of HubSpot. If you run HubSpot on a paid tier, you already have it. If you run another CRM, there is no Clearbit plan to buy, and the tools above are the options.

No. Clearbit closed its free tools on April 30, 2025: the free Clearbit Platform, the Weekly Visitor Report, the TAM Calculator, Clearbit Connect and the free Slack integration. Inside HubSpot, data enrichment is available on Starter, Professional and Enterprise subscriptions, and HubSpot's free tools are not on that list. Once you are on a paid plan, HubSpot's knowledge base says enrichment does not consume HubSpot Credits (updated July 10, 2026). Buyer intent does, at 10 credits per company it adds automatically. HubSpot lists Sales Hub Starter from $20 per seat a month on monthly billing, with 500 HubSpot Credits included (hubspot.com/pricing/sales, read October 1, 2026).

HubSpot says its enrichment data is powered by HubSpot's commercial dataset, third-party providers and publicly available information from across the internet (knowledge base, updated July 10, 2026). Its product page says over 100 million company domains and 380 million email addresses are indexed. To enrich a contact, HubSpot uses the first name, last name and work email already on the record; to enrich a company, it uses the domain. That input matters when you compare alternatives. HubSpot's enrichment adds context such as job title, seniority, industry and employee count to records you already have. Finding a missing work email or a phone number is a different job, done by contact data tools such as Clu, Apollo.io or ZoomInfo. Our Apollo alternatives and ZoomInfo competitors pages compare those in depth.

People Data Labs is the most direct swap for engineers: person and company enrichment APIs, a self-serve Pro plan from $98 a month for 350 records, and no CRM in the middle. Our People Data Labs alternatives page covers the other API-first vendors. Clu's public REST API starts on the Pro plan at $89 per seat a month; Clu pricing lists every plan gate.

Verification and GDPR handling differ by vendor, so check each one's own documentation. Clu verifies a work email before it charges a credit for it, which is why a miss costs nothing. Cognism builds its offer around European compliance and phone-verified mobiles. For any vendor, ask the same three questions: where the data comes from, whether a lookup is charged when the email fails verification, and how an EU data subject can opt out. Our guide to waterfall enrichment tools explains how multi-provider lookups handle a failed check.
