If you came here because your Clearbit enrichment broke, you're not imagining it. HubSpot acquired Clearbit and folded it into Breeze Intelligence. The standalone Clearbit Enrichment API, the free tier, and the old logo/reveal endpoints have been sunset or pulled into the HubSpot ecosystem. If you were calling Clearbit as a plain API — outside HubSpot — you've effectively been orphaned.
This post is a straight, no-hype map of where to go next. I build one of the alternatives (more on that below, clearly flagged), so I'll be upfront about where my tool fits and where it doesn't — because picking the wrong category wastes weeks.
First, decide what you actually need
Most "Clearbit alternative" lists lump everything together. Don't. There are really two different jobs:
- Contacts — names, work emails, phone numbers of decision-makers. This is people data.
- Firmographics — company-level data: sector, description, tech stack, country, founded year, legal name, domain status. This is company data.
Clearbit did a bit of both, which is why its sunset hurts in two directions. Almost every alternative leans hard to one side. If you only need to know what a company is (to qualify a signup, route a lead, segment an account), you do not need a contact database — and you shouldn't pay for one.
A second axis matters too: how the data is sourced and billed.
- Static database (refreshed monthly/quarterly) vs live (read at request time).
- Subscription credits that expire vs pay only for successful calls.
- Locked into a platform/CRM vs a plain API you call from anywhere.
The alternatives, honestly
Apollo.io — Contacts + company data + a sales-engagement platform. Its API enriches by email, domain, or LinkedIn URL and returns both contact and firmographic fields. Pick it if you genuinely need decision-maker contacts and outreach tooling in one place.
ZoomInfo — The enterprise heavyweight: huge contact database, intent signals, org charts. Pick it if you have an enterprise budget and need depth and coverage at scale.
People Data Labs — A developer API over a large company/person dataset (70M+ company profiles), strong on headcount. Database-backed, credit-based (you're charged on a successful response). Pick it if you need scale and headcount data via a clean API.
Crustdata — Real-time-leaning B2B data with 250+ company datapoints (headcount trends, funding, tech, web traffic) and webhook signals. Pick it if you want change signals (job changes, funding) and don't mind enterprise-ish pricing.
Clay — Not a data source but an orchestration layer that routes across 150+ providers and runs workflows. Since 2026 it no longer charges failed lookups. Pick it if you want a no-code table to combine many providers.
Enrich Layer — A developer-first API covering people, companies, and jobs, queryable by domain or name. Pick it if you want a broad unified API and are fine with subscription credits.
CDCSaaS (the one I build) — A small, honest firmographic-only API. You send a domain, you get live company data read from the site (name, sector, description, tech stack, socials, domain status) plus official-registry data for French (SIRENE) and UK (Companies House) companies (legal name, founded year, country, city). Every field is tagged with its source, and you're billed only when the call returns real data. Pick it if you only need company firmographics, you're tired of expiring credits and platform lock-in, and you value being able to audit where each field came from. Don't pick it if you need contact emails/phones — it doesn't do that, on purpose.
What "auditable" looks like in practice
Here's a real, live response for free.fr (trimmed for readability — tested in production while writing this):
{
"domain": "free.fr",
"firmographics": {
"name": "Free",
"legal_name": "FREE",
"sector": "Télécommunications et services internet",
"founded_year": 1999
},
"geo": { "country": "France", "city": "PARIS", "region": null },
"tech": { "tech_stack": ["Nginx", "Next.js"], "domain_status": "active" },
"data_sources": {
"name": "web",
"legal_name": "official_registry",
"founded_year": "official_registry",
"country": "official_registry",
"tech_stack": "web"
},
"meta": { "fetched_at": "2026-06-21T20:32:41Z", "cached": true }
}
Two things worth copying as evaluation criteria, whatever tool you choose:
-
Provenance per field. Notice
data_sources:namecame from the website, butlegal_name,founded_yearandcountrycame from the official registry. When a field is wrong, you know why. Most APIs hand you a flat blob with no idea where each value originated. -
Explicit nulls. A field the API can't verify comes back
null, not a guess. An API that "fills" every field is often inventing — and an invented country or sector is worse than a blank one, because you trust it.
So which should you pick?
- Need contact emails/phones? Apollo or ZoomInfo. Stop reading the firmographic tools.
- Need huge scale + headcount/funding signals? People Data Labs or Crustdata.
- Want a no-code layer over many providers? Clay.
- Just need clean, auditable company firmographics by domain — without a CRM, without credits that expire, without paying for misses? That's the lane CDCSaaS is built for.
There's no single "Clearbit replacement," because Clearbit was several products. The honest move is to name the one job you actually need done, then pick the tool that does that job well instead of the one with the longest feature list.
If firmographics-by-domain is your job, you can try CDCSaaS free — no signup for the first lookup: https://tools.coinduciel.com. Drop in a domain and you'll see the live data and its sources, same shape as above.
Disclosure: I build CDCSaaS. I've tried to keep the comparisons fair — if you spot something off about another tool here, tell me and I'll correct it.
