TL;DR: For most startup GTM teams: Apollo.io for all-in-one outreach and enrichment, Clay for waterfall enrichment across 150+ sources, Cognism for EMEA phone data and GDPR compliance, and Breeze Intelligence for teams on HubSpot. Most tools offer free tiers; enterprise tiers are quote-based.

Best Data Enrichment Companies for GTM Teams (2026)

Last updated: June 2026

The top data enrichment companies are Apollo.io (All-in-one: 265M+ contacts with prospecting, enrichment, and outbound sequences in one platform, Transparent self-serve tiers, free tier available), Clay (Waterfall enrichment across 150+ sources, no-code workflow builder, Claygent AI research agent, Free to Enterprise, credit-based), Cognism (400M+ contacts, GDPR-compliant, phone-verified Diamond Data for EMEA markets, Standard/Pro credit tiers, enterprise custom), Breeze Intelligence (Native HubSpot enrichment: 40+ attributes at form submission, form shortening, buying intent signals, Credit packs: 100, 1,000, or 10,000 credits).

Data enrichment split into two distinct tracks in 2026: contact-level data (emails, phone numbers, firmographics) and account-level intelligence (buying signals, hiring events, funding rounds). Contact data has commoditized fast. Nearly every tool now offers a free tier and self-serve plans. The real differentiation is match rate for your specific ICP, signal freshness, and how cleanly data flows into your sequencer or CRM without manual cleanup.

What Should You Look for in a Data Enrichment Company?

Most comparison articles rank enrichment tools by database size. That is the wrong frame for startup GTM teams.

The right question is: does this tool cover your specific ICP verticals, and does it push clean data directly into your CRM or sequencer? A 500-million-contact database that misses your niche delivers less value than a smaller, more accurate dataset that matches your actual buyers.

Four factors matter for early-stage teams: match rate on your real prospect list, integration depth with your CRM and sequencer, pricing that works at your volume, and compliance coverage for the regions you sell into. The tools below vary significantly on all four. The evaluation framework at the end of this guide shows you how to run a 30-minute pilot to find out which tool wins on your data.

Quick Comparison: Best Data Enrichment Companies

Here is how the seven tools compare across the dimensions that matter most for startup GTM teams.

Best Data Enrichment Companies, Reviewed

Apollo.io

Apollo.io combines a 265-million-contact B2B database with built-in prospecting and outbound sequences, making it the most practical all-in-one option for startup sales teams. You can find a prospect, enrich their profile with technographics and recent job postings, and drop them into an email sequence without leaving the platform. Transparent, self-serve pricing means you can start testing with real data without a sales call.

Best for: SMB and mid-market sales teams running outbound sequences who want enrichment and prospecting in one tool without stitching together three vendors.

Key features:

• 265M+ contacts and 30M+ company profiles with multi-attribute enrichment
• API responses include technographics, job posting signals, and recent company news
• Built-in sequence engine with email, phone, and LinkedIn step types
• CRM integrations with Salesforce and HubSpot
• Credit-based system with self-serve free and paid tiers

Pricing:

• Transparent self-serve tiers with a free entry plan
• Paid tiers scale credits and enable API access; large-scale enrichment at volume may require a custom enterprise contract

Strengths: The only tool on this list that handles prospecting, enrichment, and outbound sequences in one place. Self-serve pricing means you evaluate with real data before committing budget.

Weaknesses: API rate limits and credit usage can be restrictive on lower-tier plans. Heavy-volume enrichment (tens of thousands of records) will push you toward a custom enterprise plan.

Choose Apollo.io when: Your team wants to run outbound sequences without stitching together multiple tools. Works best for U.S.-heavy ICPs. For EMEA phone coverage, Cognism is a stronger fit.

Clay

Clay runs waterfall enrichment across 150+ data providers, pulling contact and account data from multiple sources and combining the best result for each field. When Apollo misses a record, Clay tries Clearbit, then PDL, then a half-dozen other sources automatically. RevOps teams use it to build the full enrichment pipeline: pull a list, waterfall-enrich across providers, score against ICP criteria, route clean records to the sequencer. Claygent, Clay's built-in AI research agent, handles unstructured research tasks like finding a company's recent press coverage or identifying a hiring signal from job postings.

Best for: RevOps engineers and growth teams who need multi-source enrichment coverage that no single provider can match, and who have the technical capacity to configure workflows.

Key features:

• Waterfall enrichment across 150+ data sources including Apollo, Clearbit, People Data Labs, and LinkedIn
• Claygent AI research agent for custom, unstructured data lookups
• No-code workflow builder with conditional logic and branching
• CRM enrichment and automated lead scoring
• Account and contact scoring with custom field mapping

Pricing:

• Free, Starter, Explorer, Pro, and Enterprise tiers
• All paid plans are credit-based; Enterprise is custom

Strengths: Nothing else aggregates 150+ sources in a configurable waterfall. When a single provider misses your ICP niche, Clay will find data somewhere in the stack. Flexible enough to power almost any enrichment workflow.

Weaknesses: Requires more setup and technical familiarity than plug-and-play tools. Each of the 150+ providers operates under its own compliance standards, which creates variability that matters for GDPR-sensitive outreach.

Choose Clay when: You need enrichment coverage that no single provider matches, and you have a RevOps resource who can configure and maintain workflows. Not a quick-start solution for a two-person team with no technical capacity.

Cognism

Cognism built its differentiation around EMEA data quality and compliance. Its phone-verified Diamond Data is a curated dataset of mobile numbers verified through live calling, giving sales reps a direct line to decision-makers without relying on scraped numbers. For teams selling into Europe, this is the clearest differentiator in the category: GDPR-compliant coverage in markets where U.S.-centric tools consistently underperform. Beyond contact data, Cognism surfaces outbound triggers like job changes, hiring signals, and funding events.

Best for: Sales teams running phone-heavy outbound into European markets who need verified mobile numbers and built-in GDPR compliance.

Key features:

• 400M+ contacts and 20M+ company profiles
• Phone-verified Diamond Data for direct mobile access
• Real-time CRM enrichment via API with continuous data refresh
• Job change alerts, hiring signals, and funding events as outbound triggers
• GDPR-compliant data collection and processing across European markets
• Native Salesforce integration and workflow automation

Pricing:

• Standard: core data access with phone-verified mobile numbers and CSV enrichment; 10,000 credits per user per year
• Pro: adds on-demand verification, premium mobile coverage, API access, company hierarchies, and intent data; 12,000 credits per user per year
• Enterprise: custom, contact required; annual contract for all tiers

Strengths: The strongest verified phone data for European outreach. GDPR compliance is built into the data model. One customer (Druva) reported 22% growth in quarterly pipeline after deploying Cognism for EMEA SDRs.

Weaknesses: Annual contracts required. No monthly option. API access is locked to Pro and above. U.S. coverage is solid but not its primary focus.

Choose Cognism when: Your ICP includes European decision-makers and your team makes phone calls as part of outbound. If you run U.S.-only outbound with low call volume, Apollo gives you more coverage per dollar without the annual contract.

Breeze Intelligence (formerly Clearbit)

Breeze Intelligence, formerly known as Clearbit, became HubSpot's native enrichment layer after HubSpot's acquisition. For teams whose GTM motion lives inside HubSpot, this integration removes the need for any external enrichment vendor. When a new contact submits a form, Breeze automatically enriches over 40 attributes including company size, industry, technology stack, and employee count without a manual step or webhook. The form shortening feature pre-fills known fields at the point of entry, reducing form abandonment while still capturing full firmographic data.

Best for: Marketing and sales teams whose entire GTM workflow runs inside HubSpot and who want zero-friction enrichment without adding another vendor contract.

Key features:

• Native HubSpot enrichment: 40+ firmographic and technographic attributes added at contact creation
• Form shortening: pre-fills known fields to reduce form friction and improve inbound conversion
• Buying intent signals surfaced inside the HubSpot interface
• Lead scoring built from enriched attributes within HubSpot workflows
• Website visitor identification: de-anonymizes traffic into named accounts

Pricing:

• Credit-based: packs of 100, 1,000, or 10,000 credits
• Bundled into HubSpot contracts for teams on eligible tiers

Strengths: The tightest HubSpot integration available. No data routing, webhooks, or separate login. Form shortening alone tends to lift inbound conversion without additional setup.

Weaknesses: Tightly coupled to HubSpot. No standalone value if you're on Salesforce or a different CRM. Some users report data accuracy limitations compared to dedicated enrichment vendors at scale.

Choose Breeze Intelligence when: HubSpot is your CRM and marketing automation platform. Avoid if you run Salesforce as your primary source of truth or need multi-CRM flexibility.

Lusha

Lusha is designed for speed. SDRs use the browser extension to enrich contacts directly from LinkedIn profiles or company websites, pulling a direct dial or verified email in a few clicks without leaving the page. The credit-based model with a free entry tier makes it easy to evaluate data quality on your real ICP before committing. For individual contributors who need on-the-fly contact data during active prospecting sessions, Lusha removes friction at the top of the workflow.

Best for: SDRs and individual contributors who need fast, ad-hoc contact enrichment while prospecting on LinkedIn without complex platform setup.

Key features:

• Browser extension for LinkedIn and company website enrichment
• 100M+ contacts and 20M+ company profiles
• Free monthly credits for evaluation, credit-based plans for teams
• Single and bulk enrichment APIs for more systematic workflows
• CRM push integrations for common sales platforms

Pricing:

• Free entry tier with monthly credits
• Paid plans scale credits and enable team features and API access
• Higher-tier API limits require custom enterprise plans

Strengths: Lowest barrier to start. The browser extension fits directly into how SDRs prospect on LinkedIn. Free credits let you validate data quality on your specific ICP before spending.

Weaknesses: International coverage and mobile number accuracy are inconsistent, particularly outside North America. Not built for high-volume automated enrichment pipelines. Works as a primary tool for small teams but often needs supplementing for global outreach.

Choose Lusha when: You have a small SDR team prospecting manually on LinkedIn and want individual-level contact data with minimal setup. Not the right choice as your primary enrichment layer for automated outbound at scale.

People Data Labs (PDL)

People Data Labs is built for engineering and data teams, not sales reps. It provides person, company, and IP enrichment through flexible APIs and bulk processing endpoints, with transparent usage-based pricing and thorough documentation. Teams building custom data products, recruiting platforms, or automated CRM enrichment pipelines choose PDL because they want clean, reproducible output from a single provider rather than a black-box tool that abstracts away the underlying data.

Best for: Data engineers and RevOps teams building custom enrichment pipelines who need API-first access with public, usage-based pricing and no minimum contract.

Key features:

• Person, company, and IP enrichment via REST APIs
• Bulk Enrich endpoint for processing large datasets without rate-limit friction
• Self-serve Batch Enrich UI for non-technical teammates
• Transparent, usage-based pricing with public plans on the website
• API playground and clear documentation for rapid developer testing

Pricing:

• Transparent, credit-based pricing with public self-serve plans
• Usage scales with data volume; enterprise plans available for high-volume needs

Strengths: The most transparent pricing model in this category. Excellent API docs and a developer playground for fast onboarding. Clean, reproducible output that works well in automated pipelines.

Weaknesses: Pure data provider only. No CRM integration layer, sequencer, or enrichment UI for non-technical users. You need to build or buy all downstream tooling.

Choose PDL when: You are building a custom data product or running an automated enrichment pipeline where you control the integration layer. If you want turnkey enrichment that flows directly into Salesforce or a sequencer without engineering work, use Apollo or Cognism instead.

ZoomInfo

ZoomInfo is the enterprise standard for U.S. B2B data. The platform covers 500 million contacts and 100 million companies, processed through multi-source verification that handles over 1.5 billion data points daily. Its WebSights feature de-anonymizes website traffic, turning anonymous visitors into identifiable named accounts with associated firmographic data. The scale and partner ecosystem make it the foundational choice for large GTM organizations with dedicated RevOps resources.

Best for: Enterprise sales and marketing teams with U.S.-heavy GTM motions who need high-volume, reliable contact data and website visitor identification at scale.

Key features:

• 500M contacts and 100M companies with multi-source verification
• WebSights for identifying named accounts from anonymous website traffic
• 200+ firmographic attributes per company profile
• Real-time form enrichment and CRM data maintenance workflows
• Deep partner ecosystem covering major CRMs and marketing automation platforms

Pricing:

• Enterprise pricing, quote-based; represents a significant investment per the vendor's own positioning

Strengths: The most comprehensive U.S. B2B contact coverage in the category. Strong direct-dial phone number accuracy for high-volume SDR teams. The partner ecosystem means it connects to almost any GTM tool your team already runs.

Weaknesses: Pricing requires a sales call and is built for enterprise budgets. Implementation requires dedicated data governance resources to manage CRM field mapping and prevent data quality issues. EMEA coverage exists but is not the core strength.

Choose ZoomInfo when: You run a large U.S. B2B sales team and need the broadest contact coverage with direct-dial accuracy. For seed-to-Series-B teams, the cost and setup overhead typically make Apollo or Cognism a better starting point.

How to Pick a Data Enrichment Company for Your Stack

The tools above cover different use cases, budgets, and geographies. Making the right choice comes down to testing, not marketing claims.

1. Test match rate with your real ICP first.

Every vendor will claim high accuracy. The only number that matters is their match rate on your specific prospect list. Take a sample of 200 to 500 accounts from your target market, give each vendor the same seed data (company domain or name), and measure how many records come back with usable contact information. Match rates vary significantly by vertical, company size, and geography. Run this test before signing anything.

2. Check integration depth with your CRM and sequencer.

A native HubSpot integration is meaningless if you run Salesforce. Confirm that the tool has a direct connector to your CRM. Then check your sequencer: if you send outbound through Instantly, Smartlead, Outreach, or Salesloft, verify that enriched records route cleanly without manual CSV exports. Tools that require a Zapier bridge for basic CRM syncing will create data hygiene debt over time.

3. Calculate actual cost at your volume.

Enrichment tools price in credits, per-record fees, or user-based subscriptions. Before comparing sticker prices, estimate your actual monthly volume: how many new contacts do you enrich each month, and how often do you refresh existing records? Run the math on each pricing model at your expected volume. A generous credit bundle that sounds affordable can run out fast if you enrich 10,000 records per month.

4. Confirm compliance coverage for your target regions.

If you sell into Europe, GDPR compliance is not optional. Cognism is the strongest choice here. If you sell into California, CCPA applies to consumer-adjacent contact data. Ask vendors directly how they source and consent to the data for your primary target geography, not their global policy statement.

5. Ask about data decay and refresh rate.

B2B contact data decays at roughly 30% per year as people change jobs, get promoted, or leave companies. A database that was accurate 18 months ago is missing a third of its records by now. Ask vendors how frequently they refresh their underlying dataset and whether they offer continuous CRM enrichment to keep records current automatically.

Once you have results from a matched pilot against your real ICP data, the decision usually becomes clear. Pick one primary tool for the bulk of your enrichment workflow, and add a specialized tool for the gaps (Clay for waterfall enrichment, Cognism for European phone data).

Automate Your Data Enrichment Workflows

The tools above handle the data layer. Apollo gives you 265 million contacts. Clay aggregates 150+ sources to fill the gaps. Cognism verifies the phone numbers. Breeze Intelligence keeps your HubSpot CRM clean automatically.

But data enrichment involves more than picking a vendor. Someone still has to handle the execution work: scraping and building the initial prospect lists, running waterfall enrichment across providers, scoring enriched contacts against your ICP criteria, and routing clean records to your sequencer with the right personalization fields populated.

Miniloop handles that busywork. We build and run GTM workflows for your team:

• Pull targeted prospect lists from Apollo or LinkedIn based on ICP criteria
• Run multi-source enrichment workflows, including waterfall enrichment through Clay, to maximize match rate
• Score contacts against your ICP and flag high-priority accounts for immediate outreach
• Route enriched, scored records directly to Instantly, Smartlead, Outreach, or Salesloft with personalization fields populated
• Set up signal-based triggers so your team gets notified when a target account hires a new VP of Sales or closes a funding round

Whether you have a RevOps hire, are recruiting one, or are doing this yourself right now, Miniloop handles the execution layer so your team spends time on conversations rather than data cleanup.
