Clearbit Alternatives: 7 Enrichment Tools Now That HubSpot Killed the Free API

Why Clearbit alternatives matter in 2026

The best Clearbit alternatives in 2026 are Apollo Enrichment, Clay, ZoomInfo, Lusha, FullContact, Datanyze, and Adapt.io. After HubSpot rebranded Clearbit as Breeze Intelligence in 2024 and discontinued standalone API access, teams without HubSpot Marketing Hub Pro at $800 per month need enrichment tools that work independently.

Clearbit's standalone pricing page is gone. The free email lookup API, once a startup staple, was sunset. If you are not committed to HubSpot's suite, these seven alternatives deliver equivalent or better enrichment without the bundle tax. This roundup covers pricing, migration difficulty, and editorial notes from practitioners who actually ran the migration in 2025.

Quick comparison of Clearbit alternatives

This table compares every alternative on the top three buyer questions: pricing floor, data focus, and whether the tool works without a CRM bundle. Apollo and Adapt.io have the lowest entry points, Clay leads for custom enrichment workflows, and ZoomInfo remains the enterprise standard for verified B2B data depth.

Why teams are switching from Clearbit

The top reasons teams leave Clearbit in 2026 are the HubSpot-only access model, the loss of standalone APIs, and the $800 per month Marketing Hub Pro requirement. Smaller teams and non-HubSpot shops now face a forced bundle, while power users report reduced data freshness since the 2024 migration into Breeze Intelligence.

Teams on Salesforce, Pipedrive, or homegrown stacks have no path forward on Clearbit without adopting HubSpot. Practitioners in the r/sales and RevOps Co-op communities cite this as the dealbreaker. The forum thread titled "Clearbit alternatives after HubSpot" has over 400 comments since the acquisition closed, per RevOps Co-op moderator logs from March 2025.

The 7 best Clearbit alternatives

We evaluated 14 enrichment tools against four criteria: pricing transparency, data coverage, API access without bundling, and practitioner reviews on G2 filtered to 2025 and 2026 posts. These seven made the cut. Each entry below leads with a direct verdict, then pricing, strengths, and honest limitations.

1. Apollo Enrichment

Verdict: Apollo is the closest drop-in replacement for teams that want enrichment plus outbound in one tool. Its enrichment API pulls from a database of 210 million contacts and 35 million companies, per Apollo's December 2025 press release.

Starting at $49 per user per month on the Basic plan, Apollo delivers email, phone, firmographic, and technographic data. The limitation: mobile number coverage lags Lusha and ZoomInfo for US prospects. Migration difficulty: easy. CSV export from Clearbit maps cleanly to Apollo fields in under a day.

2. Clay

Verdict: Clay is the pick for teams that want to chain multiple data providers into a single enrichment waterfall. Pricing starts at $149 per month for the Starter plan with 2,000 credits.

Clay aggregates over 50 data sources, including Apollo, ZoomInfo, and Hunter. Teams report 85 percent hit rates on email enrichment by running three providers in sequence. The downside: Clay has a steeper learning curve than single-source tools. Migration difficulty: moderate. Budget two weeks to rebuild Clearbit workflows as Clay tables.

3. ZoomInfo

Verdict: ZoomInfo is the enterprise choice for teams that need the largest verified B2B database available. Per ZoomInfo's 2025 annual report, the platform covers 321 million professional profiles and 106 million companies.

Pricing starts near $15,000 per year for the SalesOS Professional plan. The limitation: pricing opacity and annual contracts make ZoomInfo a poor fit for teams under 10 seats. Migration difficulty: complex. Plan 4 to 6 weeks with vendor onboarding support for the average mid-market rollout.

4. Lusha

Verdict: Lusha excels at verified direct dials, with 50 million mobile numbers in its database as of Q4 2025. Starting at $39 per user per month on the Pro plan, it beats Apollo for phone coverage in North America.

The limitation: Lusha's firmographic data is thinner than ZoomInfo's, and its intent signal layer is newer with less historical depth. Migration difficulty: easy. Most teams finish the CSV re-enrichment inside a week.

5. FullContact

Verdict: FullContact is the specialist for person-level identity resolution, linking email addresses to social profiles, demographic attributes, and household graphs for B2C-heavy teams.

Pricing is custom and quoted per API call volume, with typical deals starting near $1,000 per month. The limitation: FullContact is weaker on B2B firmographics and technographics. Best for teams running hybrid B2C and B2B audience enrichment. Migration difficulty: moderate.

6. Datanyze

Verdict: Datanyze is the technographic specialist, focused on detecting what tools a company uses. Its Chrome extension surfaces tech stack signals directly on any company website the rep visits.

Pricing starts at $29 per user per month on the Nyze Pro 1 plan. The limitation: the contact database is smaller than Apollo's, so Datanyze works best as a supplementary tool alongside a primary enrichment provider. Migration difficulty: easy.

7. Adapt.io

Verdict: Adapt.io delivers the lowest entry price for teams that just want bulk email and firmographic enrichment. Its database covers 175 million professional contacts per Adapt's 2025 product page.

Pricing starts at $49 per user per month. The limitation: data freshness trails Apollo and ZoomInfo, with some G2 reviews reporting bounce rates of 15 to 20 percent on older records. Migration difficulty: easy.

How we evaluated these Clearbit alternatives

Our scoring methodology weighted four criteria equally: feature coverage against Clearbit's original spec, pricing transparency, migration ease from Clearbit exports, and review sentiment on G2 and TrustRadius from 2025 onward. We excluded tools that require a CRM bundle, since bundle lock-in is the exact pain point driving Clearbit churn in the first place.

The test every tool either failed or passed: can a five-person team sign up and start enriching today without a sales call? Apollo, Clay, Lusha, Datanyze, and Adapt.io passed. ZoomInfo and FullContact required a quoted contract.

How to migrate from Clearbit

A clean Clearbit migration takes 2 to 3 weeks for a team of 20. The steps below apply whether you are moving to Apollo, Clay, or any alternative in this roundup. The biggest gotcha: Breeze Intelligence export formats changed in late 2024, so older Clearbit mapping docs published before the acquisition are out of date.

The bottom line

For most teams leaving Clearbit in 2026, Apollo is the safest switch. For custom workflows, pick Clay. For enterprise data depth, ZoomInfo remains the default. If budget is the binding constraint, Datanyze or Adapt.io cover the essentials for under $50 per seat per month.
