The Best Clearbit Alternative: What to Use Now That Clearbit Is HubSpot-Only
A great rep once knew every account. Now your agents do.
For years, Clearbit was the default enrichment layer for B2B go-to-market teams. One API, clean data, no ceremony. Then HubSpot acquired it, rebranded it as Breeze Intelligence, and walled it inside the HubSpot platform. On April 30, 2025, Clearbit's standalone free tools were sunset for good.
If your stack isn't HubSpot, you're no longer a customer. You're a migration project.
This piece is for the teams left holding the gap — founders, growth engineers, RevOps leads, and ABM practitioners building AI-agent go-to-market who need enrichment that works outside a CRM's walled garden.
What Actually Happened to Clearbit
HubSpot acquired Clearbit and rebranded it as Breeze Intelligence. The integration was gradual, then sudden. Breeze Intelligence is Clearbit's data, Clearbit's infrastructure, and Clearbit's brand — now licensed exclusively to HubSpot customers as a paid add-on.
The standalone API is gone. The free tools were switched off April 30, 2025. Teams that built workflows on top of Clearbit's free endpoints woke up to broken pipelines.
For HubSpot shops, the transition is manageable. For everyone else, the question is simple: what do you use instead?
Why the Usual Alternatives Fall Short
The enrichment market isn't short on vendors. Apollo, ZoomInfo, Lusha, Clearbit-shaped holes filled by a dozen point solutions. The problem isn't availability. The problem is architecture.
Most teams end up stitching together multiple tools — one for email verification, one for firmographics, one for technographics, one for intent signals. Each with its own contract, its own rate limit, its own data model, its own definition of "employee count." You pay per field, per source, per seat, per month.
And none of it tells you why it returned what it returned.
That matters more than it used to. When a human reads an enrichment result, they apply judgment. When an agent acts on it — writing a sequence, routing a lead, triggering a workflow — it acts at machine speed with no judgment at all. Bad data, fabricated data, silent fallbacks: the agent doesn't hesitate. It just executes.
The cost of bad enrichment isn't a wrong field in a CRM anymore. It's an autonomous loop doing the wrong thing at scale.
What Agent-Ready Enrichment Actually Looks Like
Building for AI agents changes the requirements entirely. An agent doesn't need a dashboard. It needs:
- Structured, canonical fields it can reason over consistently
- Source attribution so it knows where a fact came from
- Confidence scores so it knows how much to trust it
- A protocol it can call directly — not a webhook, not a Zapier zap
This is the gap the market hasn't closed. Enrichment was designed for humans reading dashboards. The tooling hasn't caught up to agents running loops.
abm.dev: Account-Based Marketing for AI Agents
abm.dev was built for exactly this moment. Not a CRM add-on. Not a dashboard product. An API — Search, Enrich, and Create — designed to sit inside an agent's tool loop.
Eighty-Nine Canonical Fields. Every One Cited.
Each enrichment call returns eighty-nine canonical fields: forty-three on the person, forty-six on the company. Every field carries a citation, a source attribution, and a confidence score.
Not "we think this is their job title." "LinkedIn says this is their job title" — with a confidence score to match.
No fabricated facts. No silent fallbacks. No mystery meat data that arrived from somewhere and can't be traced.
When your agent writes a personalized sequence, it knows what it knows — and why.
Ten Providers. One Call.
Behind a single API call, abm.dev aggregates ten data sources — LinkedIn, Hunter, Perplexity, and others — deduped, reconciled, and returned as a single coherent record.
One call, ten providers behind it. No per-source bills. No managing ten API keys, ten rate limits, ten contracts. You get the aggregate without the overhead.
Pay Per Enrichment. Credits Never Expire.
Pricing is pay-per-enrichment, not a subscription. No monthly minimums, no seat fees, no "contact us for enterprise pricing" walls.
- Thirty credits from €2.89 — €0.29 per enrichment at entry
- Two thousand credits at €0.06 per credit
- Credits never expire
- The playground is free
You enrich what you need, when you need it. The cost scales with your actual usage, not with your contract tier.
The Claude Connector: MCP-Native from Day One
This is where abm.dev separates from every enrichment vendor that predates the agent era.
abm.dev ships a Claude Connector that exposes Search, Enrich, and Create directly over the Model Context Protocol (MCP). An agent running in Claude can call enrichment as a native tool, inline, without a middleware layer, without a human in the loop.
Built for autonomous agent loops, not human dashboard-watching.
Your agent finds a target account, calls Enrich, gets eighty-nine cited fields back, and writes a personalized message grounded in verifiable data — all in a single loop iteration. That's the architecture the next generation of go-to-market runs on.
The Migration Case, Made Simply
If you were on Clearbit's standalone API or free tools, the migration path is straightforward:
| What you had | What you get with abm.dev |
|---|---|
| Single enrichment endpoint | Search, Enrich, Create |
| Firmographic + contact fields | Eighty-nine canonical fields |
| No source attribution | Citation + source + confidence per field |
| Per-call pricing | Pay-per-enrichment, credits never expire |
| REST API | REST API + MCP Claude Connector |
| HubSpot-only going forward | Fully standalone, CRM-agnostic |
No platform lock-in. No subscription you'll forget to cancel. No data you can't explain to an auditor — or an agent.
Personalization, at Scale.
Once upon a time, marketing was a person who knew you — the right detail, the right moment, the note that landed because it was true. The data's rich enough to do that again. At scale this time.
Clearbit made that possible for a generation of B2B teams. Breeze Intelligence will do the same — for HubSpot customers. The rest of the market needs an alternative that was built for where go-to-market is actually going: autonomous agents, cited data, machine-speed execution.
abm.dev is that alternative.
