Top 13 Data Enrichment Tools for B2B Teams in 2026
B2B data decays at 30% per year. We tested thirteen enrichment tools to find which ones keep your contact, company, and technographic data accurate and complete.
In 2026, data enrichment is the foundation of every B2B GTM strategy. Without accurate emails, phone numbers, firmographic data, and intent signals, your outreach falls flat, your scoring models break, and your forecasts miss. The challenge is that no single CRM data enrichment tool covers everything.
We tested thirteen data enrichment tools on coverage breadth, accuracy, API quality, and pricing. Here are the best options for B2B teams in 2026.
TL;DR
- SyncGTM ($99/mo) -- Best for waterfall enrichment across 50+ providers with AI research agents
- Clay ($167/mo) -- Best for custom enrichment workflows with 100+ provider integrations
- ZoomInfo ($15k+/yr) -- Best enterprise single-source database with intent data
- Clearbit (HubSpot) -- Best for real-time company enrichment within HubSpot
- People Data Labs ($0.01/record) -- Best API-first enrichment for developer teams
- Cognism (custom) -- Best for GDPR-compliant European data enrichment
What We Evaluated
- Data breadth -- contact, company, firmographic, technographic, intent coverage
- Accuracy -- email deliverability, phone connect rates, data freshness
- API quality -- documentation, latency, reliability, rate limits
- Waterfall support -- multi-provider sequencing and fallback logic
- Pricing model -- per-record, credit-based, flat-rate, or enterprise contracts
1. SyncGTM — Waterfall data enrichment with the highest coverage across 50+ providers
SyncGTM — Waterfall data enrichment with the highest coverage across 50+ providers
SyncGTM is built for waterfall enrichment -- querying 50+ data providers in sequence to maximize coverage for every record. Instead of relying on a single database, SyncGTM automatically falls back to the next provider when one misses a data point.
AI research agents extend enrichment beyond traditional databases. They can gather custom data from websites, news, and social profiles -- funding rounds, tech stack changes, hiring signals -- that no structured provider covers.
Native CRM integrations push enriched data to Salesforce, HubSpot, and other CRMs automatically. The workflow builder lets you trigger enrichment on record creation, schedule batch re-enrichment, and route enriched leads based on data quality scores.
Pros
- +Waterfall enrichment across 50+ providers
- +AI research agents for custom data
- +Automated CRM enrichment triggers
- +Workflow builder for enrichment pipelines
- +Free tier available
Cons
- −Newer platform -- smaller community
- −AI enrichment slower than direct API calls
Best for: Waterfall data enrichment with the highest coverage across 50+ providers
Pricing: Free tier available. Starter $99/mo. Pro $249/mo. Business $649/mo.
2. Clay — Custom enrichment workflows with 100+ provider integrations
Clay — Custom enrichment workflows with 100+ provider integrations
Clay connects to 100+ enrichment providers through its spreadsheet interface, giving you the most integration options for data enrichment. AI formulas let you build custom scoring, normalization, and routing logic on top of enriched data.
The platform shines at complex multi-source enrichment where you need different providers for different data types or segments. However, credit-based pricing makes high-volume enrichment expensive.
Pros
- +100+ enrichment integrations
- +AI formula builder
- +Custom waterfall logic
- +Strong community
Cons
- −$167/mo minimum
- −Credit-based pricing
- −No outreach features
- −Steep learning curve
Best for: Custom enrichment workflows with 100+ provider integrations
Pricing: Free trial. Launch $167/mo. Growth $446/mo. Enterprise custom.
3. ZoomInfo — Enterprise single-source enrichment with intent data
ZoomInfo — Enterprise single-source enrichment with intent data
ZoomInfo provides the largest single-source B2B database with contact, company, technographic, and intent data. For enterprise teams, it is often the first provider in a waterfall sequence due to its breadth of coverage.
Intent data from Bombora and org chart enrichment add context that most enrichment tools lack. However, the $15k+/yr minimum and declining mid-market accuracy push smaller teams toward alternatives.
Pros
- +Largest B2B database
- +Intent data and technographics
- +Org charts
- +Strong CRM integrations
Cons
- −$15k+/yr minimum
- −Declining mid-market accuracy
- −Long-term contracts
- −Seat-based pricing
Best for: Enterprise single-source enrichment with intent data
Pricing: Custom pricing. Typically $15,000+/yr.
4. Clearbit — Company-level enrichment within HubSpot
Clearbit — Company-level enrichment within HubSpot
Clearbit (HubSpot Breeze Intelligence) excels at company-level enrichment -- firmographics, employee count, revenue range, industry, and technology stack. Its real-time enrichment API is fast and well-documented.
Since the HubSpot acquisition, Clearbit is best for teams in the HubSpot ecosystem. Contact-level enrichment is weaker than competitors, and standalone access is limited.
Pros
- +Strong company and firmographic data
- +Real-time enrichment API
- +Native HubSpot integration
- +IP-to-company reveal
Cons
- −Requires HubSpot
- −Weaker contact enrichment
- −Limited phone data
- −HubSpot tier pricing
Best for: Company-level enrichment within HubSpot
Pricing: Included with HubSpot Marketing Hub Professional+.
5. People Data Labs — API-first enrichment for developer teams and waterfall sequences
People Data Labs — API-first enrichment for developer teams and waterfall sequences
People Data Labs offers API-first enrichment at $0.01/record with 1.5B+ person records. It is one of the most cost-effective enrichment providers for teams building custom data pipelines or feeding into waterfall workflows.
The API is clean, fast, and well-documented. PDL is commonly used as a provider within SyncGTM or Clay waterfall sequences rather than as a standalone enrichment tool.
Pros
- +$0.01/record pricing
- +1.5B+ person records
- +Clean, fast API
- +Volume discounts
Cons
- −API only -- no UI
- −No CRM integrations
- −Requires engineering resources
- −Quality varies by region
Best for: API-first enrichment for developer teams and waterfall sequences
Pricing: Pay-per-record starting at $0.01. Volume discounts available.
6. Cognism — GDPR-compliant European data enrichment with verified mobiles
Cognism — GDPR-compliant European data enrichment with verified mobiles
Cognism is the leading enrichment provider for European B2B data with full GDPR compliance. Its Diamond Data offering provides phone-verified mobile numbers with industry-leading connect rates.
For teams selling into European markets, Cognism data quality exceeds US-focused competitors. The platform includes intent data from Bombora and integrates with major CRMs and outreach tools.
Pros
- +GDPR-compliant European data
- +Diamond Data phone-verified mobiles
- +Intent data from Bombora
- +Strong European coverage
Cons
- −Custom pricing -- typically expensive

7. FullContact — Identity resolution and data unification across systems
FullContact — Identity resolution and data unification across systems
FullContact specializes in identity resolution -- matching fragmented data points (email, phone, social profiles, device IDs) to build unified person and company records. This is different from traditional enrichment; it focuses on connecting the dots across data silos.
For B2B teams with data spread across multiple systems, FullContact identity graph helps deduplicate and unify records. It integrates via API and is commonly paired with other enrichment providers.
Pros
- +Identity resolution and data unification
- +Multi-identifier matching
- +Real-time API
- +Privacy-focused architecture
Cons
- −Not traditional enrichment -- focused on identity
- −Custom pricing
- −Requires technical integration
- −Limited standalone value
Best for: Identity resolution and data unification across systems
Pricing: Custom pricing based on volume and use case.
8. Apollo.io — Budget enrichment with prospecting and outreach included
Apollo.io — Budget enrichment with prospecting and outreach included
Apollo provides B2B data enrichment from its 275M+ contact database alongside prospecting and outreach. Its CRM enrichment feature automatically fills in missing fields on Salesforce and HubSpot records.
For teams that want enrichment plus outreach in one platform, Apollo delivers the best value at $49/mo. However, single-source enrichment means coverage gaps compared to waterfall approaches.
Pros
- +275M+ contacts
- +CRM auto-enrichment
- +Built-in outreach
- +Free tier
Cons
- −Single source
- −Email accuracy issues
- −Credit limits
- −No waterfall
