Clearbit Is Now HubSpot-Only: 7 Company Enrichment API Alternatives for Developers

If you've been using Clearbit's API for company enrichment, you've probably noticed the changes. Since HubSpot acquired Clearbit and rebranded it as Breeze Intelligence, the standalone API is being sunset. If you're not on HubSpot, you need a new plan. Finding a solid clearbit alternative is no longer optional — it's urgent. Your enrichment pipeline is on borrowed time, and migration is the only path forward.

This guide breaks down 7 company enrichment API alternatives that can replace Clearbit in your stack. We'll compare features, pricing, data coverage, and show you exactly how to migrate — including code examples. Whether you're building a CRM integration, a lead scoring engine, or a sales intelligence pipeline, one of these will fit.

What Happened to Clearbit?

Here's the short version of the Clearbit migration timeline:

• November 2023: HubSpot acquires Clearbit for an undisclosed amount.
• Early 2024: Clearbit begins integrating into the HubSpot ecosystem. Standalone signups are paused for new customers.
• Mid 2024: Clearbit is officially rebranded as Breeze Intelligence, a native enrichment layer inside HubSpot's CRM platform.
• 2025 onwards: Standalone API access is progressively restricted. Existing API keys continue to work with limited support, but no new features, no new plans, and eventual sunset.

The bottom line: if you're not a HubSpot customer, Clearbit is no longer building for you. The HubSpot blog has positioned Breeze Intelligence as a CRM-native feature, not a developer API. The enrichment endpoints you relied on — /v2/companies/find, /v2/people/find — are living on legacy infrastructure with no roadmap.

For developers who built pipelines around Clearbit's clean, RESTful API, this is a frustrating situation. You had a reliable, well-documented company data API that just worked. Now you need a clearbit replacement that matches or exceeds what you had — without locking you into a CRM you don't use.

What to Look for in a Clearbit Replacement

Before jumping into the alternatives, let's establish what actually matters when evaluating a company enrichment API. Not all data providers are created equal, and your use case will determine which trade-offs are acceptable.

Data Coverage

At minimum, you need firmographic data: company name, domain, industry, employee count, revenue range, location, and founding year. Beyond that, look for technographic data (tech stack detection), social profiles, and funding history. The more dimensions you can enrich in a single call, the fewer vendors you need.

API Response Time and Reliability

If enrichment is in your signup flow or lead routing logic, latency matters. Look for providers with sub-second response times and 99.9%+ uptime SLAs. Check their status pages — not just their marketing pages.

Pricing Model

Clearbit used a subscription model with tiered API call limits. Some alternatives use per-request pricing (pay only for what you use), while others bundle enrichment into larger platform subscriptions. For most developer use cases, credit-based or per-request models offer better cost control.

Data Freshness and Accuracy

Stale data is worse than no data. Ask how often the provider refreshes their records. Some rely on periodic crawls (monthly or quarterly), while others use real-time verification. If a company raised a Series B last week, will the API know about it?

Ease of Migration

How similar are the endpoints to Clearbit's? Can you swap out the base URL and auth header, or do you need to rewrite your data mapping layer? The less code you change, the faster you ship.

Bonus: Real-Time Signals

This is where the market is moving. Static enrichment (here's the company data at this moment) is table stakes. The next generation of enrichment APIs also deliver real-time signals: funding events, hiring surges, leadership changes, product launches, and expansion moves. This turns your enrichment pipeline into an intelligence pipeline.

7 Best Clearbit Alternatives for Company Enrichment

Here are the top enrichment API comparison picks for developers who need to move off Clearbit. Each is evaluated on data quality, API design, pricing, and unique strengths.

1. BounceWatch API — The Signal-Enrichment Hybrid

BounceWatch is the only API on this list that combines traditional company enrichment with 40+ real-time business signals in a single platform. Instead of stitching together a firmographic API and a separate signals vendor, you get both from one endpoint.

What it does:

• Full company data enrichment: firmographics, funding history, team data, tech stack, competitors
• 40+ real-time signals: funding rounds, hiring surges, geographic expansion, product launches, leadership changes, and more
• Modular enrichment: request only the data modules you need (business, funding, team, signals, competitors) to optimize cost
• Company database with 30M+ companies indexed

Unique angle: Most enrichment APIs give you a static snapshot. BounceWatch layers in what's happening right now at that company. If a prospect just raised funding, expanded to a new market, or started hiring for a role that matches your product — you know about it in the same API response.

Pricing: Credit-based, pay per request. No monthly minimums. Each enrichment module costs a set number of credits, so you only pay for the data you actually use.

Best for: Teams that want enrichment + intelligence in one API call. Sales teams running signal-based outbound. Developers building lead scoring that factors in real-time company activity.

Code example:

// Enrich a company with business data + signals
const response = await fetch('https://api.bouncewatch.com/v1/company/enrich?domain=stripe.com&modules=business,signals', {
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY'
  }
});

const data = await response.json();

console.log(data.company.name);        // "Stripe"
console.log(data.company.industry);    // "Financial Technology"
console.log(data.company.employees);   // 8000+
console.log(data.signals[0].type);     // "product_launch"
console.log(data.signals[0].title);    // "Stripe launches embedded finance toolkit"

2. Apollo.io API

Highly rated on G2, Apollo.io has built a massive database of contacts and companies. Their API provides both person-level and company-level enrichment, plus built-in sequence and outreach tools.

Strengths:

• 275M+ contact database with email and phone data
• Company enrichment with firmographic and technographic data
• Built-in email sequences and engagement tracking
• Generous free tier (limited API calls)

Weaknesses:

• More contact-focused than company-focused — company data depth is secondary
• Rate limits are tight on free and lower tiers
• API design is oriented around their platform, not standalone enrichment
• No real-time signal data

Pricing: Free tier available (limited). Paid plans from $49/mo with higher API limits. Enterprise pricing for bulk enrichment. See how it compares directly: BounceWatch vs Apollo.

Best for: Teams that need contact enrichment alongside company data, especially if they also want outbound sequence tools in the same platform.

3. People Data Labs (PDL)

People Data Labs offers one of the largest person and company datasets available via API. With 1.5B+ person records and 30M+ company records, it's a raw data powerhouse often used by data teams for bulk enrichment and analytics.

Strengths:

• Massive dataset with global coverage
• Flexible query API: search by domain, name, LinkedIn URL, and more
• Good for bulk enrichment jobs (thousands of records at once)
• Detailed person-company relationship data

Weaknesses:

• Raw data with no intelligence layer — no signals, no insights
• Pricing can be complex with different rates for different data types
• Requires more post-processing than Clearbit's clean responses
• Steeper learning curve for the query API

Pricing: Pay-per-record model. Bulk pricing available. Free sandbox for testing with limited data.

Best for: Data engineering teams building internal enrichment databases or running large-scale batch enrichment jobs.

4. Hunter.io API

Hunter.io started as an email finder and has expanded into company data enrichment. Their API is clean, well-documented, and reliable — a favorite among developers who need email verification alongside basic company info, often discussed on StackOverflow and dev.to.

Strengths:

• Excellent email finding and verification
• Clean REST API with good documentation
• Domain search returns all known emails at a company
• Reliable uptime and fast response times

Weaknesses:

• Company data is secondary to email data — limited firmographic depth
• No technographic data, no funding data, no signals
• Not a full Clearbit replacement if you relied on rich company profiles

Pricing: Free tier (25 searches/mo). Paid plans from $49/mo with higher limits.

Best for: Developers who primarily need email finding/verification and only need basic company context alongside it.

5. FullContact

FullContact focuses on identity resolution — connecting fragmented data points (email, phone, social profiles, device IDs) into unified person and company profiles. It's less of a traditional enrichment API and more of an identity graph platform.

Strengths:

• Strong identity resolution across channels and devices
• Person enrichment with social profiles and demographic data
• Company enrichment from domain lookup
• Privacy-focused approach with consent-based data

Weaknesses:

• More focused on identity graph than rich company enrichment
• Company data depth doesn't match Clearbit's level
• Custom pricing with no transparent public plans
• Overkill if you just need firmographic enrichment

Pricing: Custom pricing. You'll need to talk to sales.

Best for: Marketing teams that need cross-channel identity resolution and are willing to pay for a premium identity platform.

6. Abstract API (Company Enrichment)

Abstract API offers a simple, no-frills company enrichment endpoint. Give it a domain, get back company data. It's designed for developers who want minimal complexity and fast integration.

Strengths:

• Dead simple REST API — one endpoint, one parameter
• Fast response times
• Affordable entry point for small projects
• Good documentation with code examples in multiple languages

Weaknesses:

• Limited data depth compared to Clearbit
• No signals, no funding data, no technographic data
• Smaller company database with potential gaps in coverage
• Basic enrichment only — no intelligence layer

Pricing: Free tier (100 requests/mo). Paid plans from $12/mo.

Best for: Side projects, MVPs, and small-scale enrichment needs where budget matters more than data depth.

7. Enrichlayer

Enrichlayer is a newer entrant in the company enrichment space, offering a lightweight API for basic firmographic data. It positions itself as a developer-friendly, affordable alternative to heavier platforms.

Strengths:

• Simple API design inspired by Clearbit's approach
• Pay-per-request pricing with no subscriptions
• Fast integration — familiar endpoint structure for ex-Clearbit users
• Transparent pricing

Weaknesses:

• Smaller database with less global coverage
• Less known in the market, smaller community
• Limited data points compared to established providers
• No signal or intelligence features

Pricing: Pay per request. Competitive rates for basic enrichment.

Best for: Developers who want a simple, Clearbit-like API experience at a lower price point and don't need advanced data features.

Migration Guide: Moving from Clearbit to BounceWatch API

If you've been running Clearbit in production, here's a practical guide to migrating your enrichment pipeline to BounceWatch. The goal: minimal code changes, maximum data coverage.

Step 1: Endpoint Swap

Clearbit's company enrichment endpoint looked like this:

// BEFORE: Clearbit
const response = await fetch('https://company.clearbit.com/v2/companies/find?domain=stripe.com', {
  headers: {
    'Authorization': 'Bearer CLEARBIT_API_KEY'
  }
});

const company = await response.json();
console.log(company.name);          // "Stripe"
console.log(company.category.industry); // "Internet Software & Services"
console.log(company.metrics.employees); // "5001-10000"
console.log(company.tech);             // ["nginx", "react", "ruby"]

Here's the BounceWatch equivalent:

// AFTER: BounceWatch
const response = await fetch('https://api.bouncewatch.com/v1/company/enrich?domain=stripe.com&modules=business,funding,signals', {
  headers: {
    'Authorization': 'Bearer BOUNCEWATCH_API_KEY'
  }
});

const data = await response.json();
console.log(data.company.name);          // "Stripe"
console.log(data.company.industry);      // "Financial Technology"
console.log(data.company.employee_count); // 8000+
console.log(data.company.tech_stack);    // ["nginx", "react", "ruby"]

// BONUS: You also get signals in the same response
console.log(data.signals.length);        // 5 recent signals
console.log(data.signals[0].type);       // "expansion"
console.log(data.signals[0].summary);    // "Stripe expands operations to South Africa"

Step 2: Data Field Mapping

Here's how Clearbit's response fields map to BounceWatch's structure:

Clearbit Field	BounceWatch Field	Notes
company.name	company.name	Direct match
company.domain	company.domain	Direct match
company.category.industry	company.industry	Flattened structure
company.category.sector	company.sector	Flattened structure
company.metrics.employees	company.employee_count	Numeric value instead of range string
company.metrics.estimatedAnnualRevenue	company.revenue_range	Similar range format
company.geo.city	company.location.city	Nested under location object
company.geo.country	company.location.country	Nested under location object
company.tech	company.tech_stack	Array format, similar structure
company.description	company.description	Direct match
company.foundedYear	company.founded_year	Snake_case naming
company.linkedin.handle	company.social.linkedin	Nested under social object
N/A	signals[]	NEW: Real-time company signals (not available in Clearbit)
N/A	funding.rounds[]	NEW: Full funding history with amounts and investors

Step 3: Webhook Setup for Async Enrichment

If you used Clearbit's webhook-based enrichment for asynchronous lookups, BounceWatch supports a similar pattern:

// Register a webhook for enrichment results
const webhook = await fetch('https://api.bouncewatch.com/v1/webhooks', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer BOUNCEWATCH_API_KEY',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    url: 'https://your-app.com/webhooks/enrichment',
    events: ['enrichment.completed', 'signal.detected'],
    secret: 'your_webhook_secret'
  })
});

// Now enrichment requests can be sent asynchronously
const enrichment = await fetch('https://api.bouncewatch.com/v1/company/enrich?domain=notion.so&modules=business,signals&async=true', {
  headers: {
    'Authorization': 'Bearer BOUNCEWATCH_API_KEY'
  }
});

// Response: { "request_id": "enr_abc123", "status": "processing" }
// Results will be POSTed to your webhook URL when ready

The signal.detected event type is unique to BounceWatch — you can set up webhooks that fire whenever a tracked company triggers a new signal. This is something Clearbit never offered.

Step 4: Test and Validate

Before cutting over production traffic:

1. Run both APIs in parallel for a sample of domains (100-500)
2. Compare data completeness: which fields are populated, which are null
3. Check edge cases: very small companies, non-US companies, recently founded startups
4. Measure response times under your expected load
5. Validate your data mapping layer handles all field transformations correctly

Beyond Static Enrichment: Why Signal Data Matters in Your API Pipeline

Here's the uncomfortable truth about company enrichment in 2026: static firmographic data is a commodity. Every provider on this list can tell you a company's employee count, industry, and location. That data is useful but not differentiating. Your competitors have access to the same enrichment APIs you do.

What separates high-performing sales and marketing teams is timing. Knowing that a company has 500 employees is useful. Knowing that they just posted 15 new engineering roles this week, raised a $30M Series B, and expanded into the DACH region — that's actionable intelligence.

This is why the concept of sales trigger events has become central to modern outbound strategy. And it's why the next generation of enrichment APIs are building signal layers on top of firmographic data.

"The best time to reach a prospect is when something meaningful is happening at their company. Enrichment tells you who they are. Signals tell you when to act."

Consider what happens when you layer signals into your enrichment pipeline:

• Lead scoring becomes dynamic: A company's score increases when they show buying signals (hiring for roles your product serves, adopting complementary tech, expanding into your target market)
• Outbound becomes timely: Instead of cold emails based on static firmographics, you reach out with context: "I noticed you just opened an office in Berlin..."
• Pipeline prioritization gets smarter: Route recently funded companies to your best reps automatically
• Churn prediction improves: Signals like leadership changes or hiring freezes at existing customers become early warning indicators

The Signal Tracker approach represents where the industry is heading: enrichment and intelligence unified in a single data layer. When you're evaluating a clearbit alternative, don't just ask "can it match Clearbit's data?" Ask "can it tell me something Clearbit never could?"

Which Clearbit Alternative Should You Choose?

Let's make this simple based on your use case:

• You need enrichment + signals in one API: BounceWatch. No other provider combines both at the API level.
• You need contacts more than companies: Apollo.io. Their contact database is massive.
• You need bulk data processing at scale: People Data Labs. Built for data engineering teams.
• You primarily need email finding: Hunter.io. Best-in-class for email discovery and verification.
• You need identity resolution: FullContact. If matching identities across channels is your core need.
• You need something cheap and simple for a side project: Abstract API. Lowest barrier to entry.
• You want a lightweight, Clearbit-like experience: Enrichlayer. Familiar API patterns at lower cost.

For most teams making a serious clearbit replacement decision, the question comes down to: do you want just data, or do you want data plus intelligence? If your enrichment pipeline feeds into sales, marketing, or product workflows where timing matters, the signal layer is worth considering.
