Comparison

Clearbit vs People Data Labs

For a new buyer in 2026 these are not two open options. Clearbit has joined HubSpot, sells no new standalone subscriptions and has no public enrichment API; its data now reaches users as data enrichment inside paid HubSpot hubs. People Data Labs sells a self-serve data API from a free plan, with Person Pro from $98 a month and 1 credit per match.

Which one to pick

Choose Clearbit if

You already have a Clearbit API contract and integrations that depend on it.
You run HubSpot Starter or above and want enrichment inside the CRM at no credit cost.
You want company enrichment and IP reveal managed for you rather than built in code.

Choose People Data Labs if

You are a new buyer and need an enrichment API you can sign up for today.
You want a free plan to test with: 100 credits a month.
You enrich in bulk from code: up to 100 records per call at 1 credit per match.
You need person data at scale: 1.5 billion profiles, plus company, IP and job-posting data.
You want misses on enrichment to cost nothing.

If neither fits: If you only need verified work emails for a list, a single email finder fits the job at a lower cost than a full data API. Find the emails, then verify them before sending.

Questions people ask

What does the Clearbit do?

Clearbit adds company and contact data to records: 100+ B2B attributes such as technologies, employee count, revenue and location, plus IP-to-company reveal. It has joined HubSpot, and new buyers now get that enrichment inside HubSpot's paid hubs rather than as a standalone API.

Where does Clearbit get its data?

Clearbit's enrichment page says its attributes are distilled from 250+ data sources and millions of data points. HubSpot's data enrichment, which replaces it for new buyers, is powered by HubSpot's commercial dataset, third-party providers and publicly available information.

Was Clearbit acquired by HubSpot?

Yes. Clearbit's pricing page now reads "Clearbit has joined HubSpot!", and its help center says it no longer offers new standalone Clearbit subscriptions and points new buyers to enrichment inside HubSpot.

Is Clearbit Connect free?

Clearbit Connect was retired on 30 Apr 2025 along with the other free Clearbit tools. People Data Labs has a free plan of 100 credits a month, but it hides emails and phone numbers until you pay for Pro.

Can I still get a Clearbit API key?

Not as a new customer. Clearbit is not creating new accounts, its signup page offers only "Sign up with HubSpot", and HubSpot's developer docs expose no enrichment endpoint. For a self-serve enrichment API, People Data Labs starts free and its Person Pro plan starts at $98 a month.
